Building African bioinformatics skills and expertise locally

Posted on October 26, 2006 by ILRIComms

Specialists at a new-age computing facility are seeking partnerships with international universities to develop world-class bioinformatics capacity in Africa – and Africa's first generation of bioinformaticians.

One of the great recent successes of African biosciences was mapping the genetic code of a parasite known as Theileria parva. This single-celled parasite is transmitted to cattle by biting ticks and causes East Coast fever, which kills a million cattle a year in 11 countries of Africa and is responsible for up to half of all deaths of calves kept by pastoralists there. Much of the work that contributed to this world-class scientific breakthrough, published in the prestigious journal Science, was undertaken in Africa by scientists at the International Livestock Research Institute (ILRI), in Nairobi, Kenya, in partnership with scientists at The Institute for Genomic Research (TIGR), based in the Maryland, USA.

Working with ILRI, scientists at TIGR first sequenced the genome of the T. parva parasite. Most of the subsequent work in annotating the sequence by identifying genes and assigning gene functions was performed by two bioinformatics specialists at ILRI— South African Etienne de Villiers and Kenyan Trushar Shah—using ILRI’s new high-performance computing facility at its Nairobi laboratories.

de Villiers, Shah and colleagues are hoping to build on this breakthrough to strengthen bioinformatics capacity in Africa. They are forming partnerships with leading universities worldwide with the aim of offering post- and under-graduate training in bioinformatics in and for Africa until African universities begin offering masters and doctoral degrees in this new discipline.

Genomics is the molecular characterization of all the genes in a species. It is concerned with sequencing and mapping all of the genes—together known as the genome—that make up a given species, and from this information, establishing what makes the species and the individuals within the species unique. Those working in genomics are interested to discover, for example, how genetic make up is responsible for making some species and individuals susceptible to disease while otheres tolerate or resist the same disease. The prospect of discovering such important biological factors makes genomics one of the most exciting fields in science today. Developments are rapid and new insights are being gained daily.

Bioinformatics is a combination of computer, information and biological sciences. Bioinformatics takes advantage of new computing and information technologies and exploits these to help scientists answer complex biological questions. Specialist databases and tools are used to manage the huge amounts of complex biological data being generated by genomics.

High-performance computing in and for Africa
The high-performance computing facility on ILRI’s campus in Nairobi provides local scientists with access to state-of-the-art technologies to enable them to conduct extensive and large-scale genomics research fast and cost-effectively for the first time. The facility has been established in Nairobi to serve the bioinformatics needs of ILRI and the eastern and central African scientific community. It is being managed as a shared facility by a new regional science platform called ‘Biosciences eastern and central Africa’ (BecA), whose hub is at ILRI’s Nairobi laboratories.

Etienne de Villiers explains that, ‘Exploitation of the latest genome technologies requires scientists skilled in bioinformatics and with access to high-performance computing infrastructure. The strategy behind high-performance computing is “divide and conquer”. Dividing a complex problem into smaller component tasks, that can be worked on simultaneously by computer, saves time, physical and human resources and money.

‘Bioinformatics is a relatively new specialist area. We need to raise awareness of the field here in Africa and expose people to its potential. The West has spent millions of dollars sequencing the genomes of humans, animals, plants and parasites and the resulting data are freely available on the internet. This is a vast body of knowledge that local scientists can use to solve their specific problems or to answer research questions. All scientists in Africa need to make use of these data are a computer, good internet access and bioinformatics skills.’

Raising awareness and building capacity in Africa
ILRI/BecA training courses and research projects are already taking advantage of the high-performance computing facility, which was commissioned in January 2005. In association with the Swedish University of Agricultural Sciences and the Linnaeus Centre for Bioinformatics, in Uppsala, Sweden, ILRI and BecA recently ran a three-day training workshop that introduced 30 scientists and students from eastern and central Africa to the field of bioinformatics.

BecA scientist Trushar Shah says that ‘bioinformatics is a new and dynamic field that young African scientists should be getting involved in, whether as a specialist or a user exploiting the technology to help answer a complex research question. Our recent short training course was very successful and we are organizing a further course in April 2007.’

Home grown strategies and interim partnerships
de Villiers is an advocate of home-grown strategies that take into consideration local needs to build capacity in Africa. ‘One of our primary goals is to grow the number and competence of bioinformatics developers and users in the east and central Africa region. To do that, we have to be responsive to local needs. We are raising awareness of the importance and utility of bioinformatics, providing introductory training for early-career scientists, and giving skilled bioinformaticians in the region ready access to advanced tools, support and expertise. We are also considering the longer term and how best we can contribute to building bioinformatics skills and expertise throughout Africa.

‘Local universities are working hard to build capacity but at the moment are unable to award degrees in bioinformatics. Our thrust now is to explore partnerships with leading bioinformatics institutes to enable us to make undergraduate and postgraduate training possible. We are working to link up with universities with well-established training programs in bioinformatics to offer East and Central African students masters and doctoral degree training in bioinformatics, possibly through distance learning.

‘We are also planning to link up with universities and institutes that can host these students for a few months so they can gain practical experience in the applications of bioinformatics. This way we are also training future local trainers.’

de Villiers was recently made Extraordinary Lecturer at the Bioinformatics and Computational Biology Unit of Pretoria University, in South Africa. This appointment enables him to supervise students from eastern and central Africa who are affiliated with the high-performance computing facility and wish to pursue higher degrees in bioinformatics through Pretoria University.

Innovative and collaborative veterinary organizations make vaccine available to Kenyan livestock keepers

Posted on October 16, 2006 by ILRIComms

A group of determined Kenyan livestock keepers set in motion an innovative collaboration that has benefited cattle-keeping communities throughout Kenya

Starting in 2000, word started getting out among Kenyan pastoralists that a vaccine being administered in Tanzania was succeeding in protecting cattle against East Coast fever. Kenya at that time did not condone use of this vaccine due to perceived safety and other issues, and so Kenya ’s livestock keepers could not get hold of it. In response, they began to walk their calves across the Kenya border into Tanzania to get them vaccinated.

‘East Coast fever is responsible on average for half of the calf mortality in pastoral production systems in eastern Africa . This vaccine represented a much needed lifeline for many pastoralists, and livestock keepers in Kenya wanted access to it,’ Evans Taracha, head of animal health at at ILRI explained.

‘ILRI faced a dilemma. We had produced a vaccine right here in Nairobi, at the International Livestock Research Institute (ILRI), that could protect pastoral and other cattle against East Coast fever, but, due to government regulations, our beneficiaries could not get access to it in Kenya.’

Kenya’s livestock keepers then started lobbying national authorities and called upon Vétérinaires sans Frontières (VSF)-Germany, an international veterinary NGO based in East Africa , to help them. Thus began a highly successful multi-partner collaboration.

Besides VSF-Germany, the collaboration includes ILRI, the Kenyan Agricultural Research Institute (KARI), the African Union-InterAfrican Bureau for Animal Resources (AU/IBAR), the Director of Veterinary Services (DVS), the NGO VetAgro, and the community-based Loita Development Foundation.

Gabriel Turasha, field veterinary coordinator for VSF-G said, ‘The demand for this vaccine was evident from the farmers’ actions. What we needed to prove – to the authorities restricting its use – was that the vaccine was safe, effective and a superior alternative to the East Coast fever control strategy already being used in Kenya .’

Armed with scientific evidence, the collaboration successfully lobbied the Kenyan government and then facilitated local production and local access to the vaccine. Three vaccine distribution centres have been established in Kenya and more than 10,000 calves vaccinated.

John McDermott, ILRI’s deputy director general of research, said, ‘This collaboration illustrates how the research from “discovery to delivery” can be facilitated by collaboration between research institutes, which are in the business of doing science, and development partners, which are in the business of on-the-ground delivery. This has been a great success story—and a great win for Kenya ’s pastoralists.’

This innovative collaboration has been selected as a finalist in the Consultative Group on International Agricultural Research (CGIAR) ‘Innovation Marketplace Awards’. These awards recognize outstanding collaborative efforts among CGIAR-supported centres and civil society organizations. Four winners will be announced at the CGIAR’s Annual General Meeting, to be held in Washington, DC , in December 2006.

Carlos Seré, director general of ILRI, said, ‘We are delighted to learn that this partnership has received recognition. ILRI is involved in a host of innovative collaborations and continues to seek new partners—from civil society organizations to the private sector to local research institutions—to help us deliver on our promises to poor livestock keepers in developing countries.’

Resource guide now available for research on agriculture-health linkages

Posted on July 18, 2006 by ILRIComms

A new initiative aims to improve health, reduce malnutrition and food insecurity and promote pro-poor agricultural development through closer collaboration between the agriculture and health sectors.

Research at the crossroads of agriculture and health conducted by the 15 centers of the Consultative Group on International Research (CGIAR) has been building and increasing in recent years. The CGIAR centers have a long tradition of working on nutrition, and now conduct a wide range of health-related work in the context of agriculture, such as malaria, HIV/AIDS, food safety and the health effects of pesticide use.

Since 2004, steps have been taken to co-ordinate the health-related work conducted by the 15 centers. This included the founding of a committee of the directors general of the centers, a stock-take of the centers existing health-related work, a workshop on agriculture-health research in the CGIAR and the publication of a series of briefs on ‘Understanding the Linkages between Agriculture and Health’.

In 2006, the Alliance Executive of the CGIAR endorsed the concept of a research platform on Agriculture and Health as a way to move forward.

The ‘Resource Guide on CGIAR Research on Agriculture-Health Linkages’, hosted on the website of the International Food and Policy Research Institute, is a portal to the work conducted in this area by different CGIAR centers, showing who is doing what on health.

The International Livestock Research Institute (ILRI) now has a webpage on IFPRI's website highlighting the following areas of ILRI's research in relation to human health:

Livestock keeping and human health
As part of its People, Livestock and the Environment Theme, ILRI conducts research to protect and enhance the physical human capital of the poor by developing strategies to reduce health risks and improve nutritional benefits associated with livestock keeping. Other projects focused on the use of water and feed for livestock also consider human health impacts.

Impact of livestock production on human health and nutrition
ILRI is working to improve understanding of the links between livestock keeping and the health and nutrition of poor people, particularly those engaging in smallholder livestock production and marketing. Activities under way include field studies, literature reviews and explorations of the ways in which livestock keeping might benefit the care of people with HIV/AIDS.

Zoonotic diseases
Poor people in developing countries have a high risk of exposure to zoonoses—diseases transmitted from animals to people. ILRI is helping to bridge the artificial divide between animal and human health. With over 75% of human infections having a zoonotic origin, the need to examine the epidemiological relationships between pathogens and their animal and human hosts is paramount. ILRI is putting specifically focusing on a major neglected zoonoses, Cysticercosis, a highly complex disease affecting both people and pigs. ILRI is participating in a Cysticercosis Working Group of Eastern and Southern Africa (CWGESA), which promotes effective communication, collaboration and coordination of integrated research and control activities aimed at combating cysticercosis. CWGESA and ILRI have recently developed a Cysticercosis Prevention Poster which is currently available in English, Xhosa and Afrikaans. This poster is being used for a rapid information campaign in Eastern Cape Province, South Africa where a neurocysticercosis outbreak among children has been reported.

Livestock, water quality, and human health
ILRI has recently initiated limited research on water-mediated impacts on human health and on INRM approaches to reducing health risks. Most of this research falls within ILRI’s collaboration with the CGIAR Challenge Program on Water and Food and the CGIAR Comprehensive Assessment of Water Management and Agriculture. Key issues include the transmission of water-borne pathogens such as coliform bacteria, cryptosporidium, and Fasciola that result from animal manure contaminating domestic water supplies and where simple remedial interventions are feasible

Wastewater is increasingly used for irrigation of fodder crops that fuel the growing urban and peri-urban dairy production in mega cities such as Hyderabad (India) and Faisalabad (Pakistan). ILRI in collaboration with IWMI and Indian and Pakistani public health institutions and municipal water authorities is investigating the relationship between water – soil – produce quality (fodder and milk) to assess the chain of possible contaminations (heavy metals, nitrate, parasites) and ultimately the hazards to producers (farmers, dairy producers) and consumers of livestock products in these urban areas.

Livestock feed quality and human health
Aflatoxin in milk – a possible hazard to human health: ILRI in collaboration with ICRISAT is investigating aflatoxin contamination of fodder (mainly crop residues) as a source of aflatoxin content in milk. In selected sites in Andhra Pradesh, India, close to 50% of the milk samples contained non-permissible levels of aflatoxin. At the same time, only one of the collected fodder samples (groundnut cake) contained non-permissible levels of alflatoxin. Aflatoxin in milk can clearly present a health hazard to the consumer.

Food safety associated with livestock and livestock products
This research program has focused on identifying the public health risks associated with the marketing of unpasteurized milk, with an emphasis on developing policies and technologies for improved quality and safety without jeopardizing market access for the poor. An outcome of this work has been changes in government policies towards more acceptance of raw milk marketing in several East African countries, based on the identified low risks and high dependence of resource poor people on these markets. This work is being expanded, in cooperation with IFPRI, to examine the marketing of other livestock and livestock products, particularly in South Asia. Studies provide policy-relevant analyses of the risks and economic benefits to poor farmers, market agents, and resource-poor consumers.

Demand for better quality and safe food is increasing among urban consumers, especially among affluent ones. This poses threats to the market opportunities of smallholder producers who often are unable to access technology, inputs and services to produce high quality products demanded by the market chains serving high-end consumers. ILRI research is trying to understand the nature of quality and safety attributes demanded by consumers, their willingness to pay for such attributes and how smallholders may respond to these through participation in market chains.

Vaccines, diagnostics and disease resistance
ILRI research on livestock vaccines has direct and indirect links to medical vaccine and diagnostic research. One aspect of this work involves host functional genomics as it relates to livestock diseases that can be transmitted to humans.

A project investigating resistance to trypanosomosis in cattle is shedding light on some of the basic questions of disease resistance, which may have implications for human medical treatment. ILRI researchers first identified several regions of the cattle genome in which genes contributing to resistance or susceptibility must lie. They then identified genes within a part of the bovine genome that affects anemia, a characteristic of the disease. Remarkably, significant differences between cattle breeds that are susceptible and resistant to the disease were found in one of the candidate genes. Such a result makes it possible that the gene in question is responsible for the difference in susceptibility to anemia in the two breeds. This is now being further investigated. More recent results of this trypanosomosis genomics research appear to have implications for medical research on cholesterol. For more information, contact ILRI’s Steve Kemp at s.kemp@cgiar.org

Initiatives and Networks
Urban Harvest Programme
ILRI is a member of Urban Harvest, a CGIAR initiative to use the collective knowledge and technologies of the CGIAR Centers to strengthen urban and peri-urban agriculture (UPA) practiced by the poor.

System-wide Initiative on Malaria in Agriculture (SIMA)
ILRI backstops a CGIAR-wide initiative addressing malaria in agricultural communities. The System-wide Initiative on Malaria in Agriculture (SIMA) focuses the combined skills and abilities of the agricultural and health research communities, government agencies and community-based organizations. Water- and land-use and crop- and livestock-production practices are studied across a range of agro-ecosystems in Africa to identify farming activities that encourage and discourage the breeding of the mosquito vector or alter the transmission of the disease. Research-based guidelines and tools are developed and tested for use by poor communities and the non-governmental organizations and governments that serve them.

Outreach and Events
CGIAR Challenge Program on Water and Food
ILRI, IWMI and the CGIAR Challenge Program on Water and Food is inviting individuals and organizations located in any of the ten riparian countries of the Nile River Basin to submit short well-written case studies describing traditional or contemporary innovations in technologies, in community and household practices, and in policies that result in better management of water and livestock resources. Relevant topics include the prevention of transmission of waterborne and water related zoonotic and animal diseases such as Cryptosporidiosis and Fasciolosis. This contest is offering USD 1000 for first prize, USD 500 for second prize and USD 250 for third prize. For more information, contact ILRI’s Don Peden at d.peden@cgiar.org

CGIAR Science Award for Promising Young Scientist
In 2005, ILRI scientist Simon Graham won the CGIAR Science Award for Promising Young Scientist for research leading to the development of a sensitive and robust system for identifying vaccine candidate molecules from Theileria parva that causes East Coast fever, a fatal disease of cattle in sub-Saharan Africa. Graham’s research may also contribute to ongoing efforts to control tropical theileriosis, a cattle disease which puts 250 million cattle around the world at risk. Furthermore, by using genomics to understand and fight T. parva, scientists may make advances against related parasites that cause malaria, tuberculosis, and other diseases in which killer T cells also play a role in immunity. And because T. parva launches a cancer-like illness inside the white blood cells of cattle, it may provide a model system for understanding the mechanics of cancer biology.

ILRI vaccine advances published in February 2006 PNAS journal

Posted on February 23, 2006 by ILRIComms

Public-private partnership makes major step towards improving livestock health and reducing poverty.

The devastating effects of East Coast fever on the livelihoods of small-scale farmers may one day be a thing of the past as a team of international scientists moves closer towards the development of a vaccine.

“East Coast fever is an intractable problem that ravages cattle of the poor in Africa. The good news is that this can be solved by high-tech science and technological innovations, achievable through strategic partnerships’’. Evans Taracha – ILRI East Coast Fever Vaccine Project Leader

Every year, East Coast fever destroys the small farmer’s dream of escaping poverty in Africa. Killing more than a million cattle and costing some $200 million annually, this tick-borne disease rages across a dozen countries in eastern and central Africa. Now, an international team of scientists has taken the first major step toward a vaccine to prevent East Coast fever. Their work, published in the February 13-17 early online edition of the Proceedings of the National Academy of Sciences (PNAS), shows how genomics can generate pivotal new vaccines.

In the study, scientists from five institutions, including the International Livestock Research Institute (ILRI) and The Institute for Genomic Research (TIGR), identify five vaccine targets, or candidate proteins that could form the basis for an East Coast fever subunit vaccine. Based on combined bioinformatics analyses and lab tests, these proteins appear to provide a protective immune response to the disease. “This initiative took just three years, after many years of scientists trying other methods,” remarks Vishvanath Nene, former ILRI staff member, a study author and molecular biologist at TIGR. “It’s a huge jump forward.”

To make the jump, researchers used the genome sequence of the parasite responsible for East Coast fever. A tick-borne parasite, Theileria parva, causes the disease. When ticks infected with T. parva bite cattle, they transmit the parasite, launching the disease that typically kills cattle within a month. In July, 2005, TIGR led a research team that published T. parva’s genome sequence, representing roughly 4,000 genes, in Science.

In the current study, Nene, along with Malcolm Gardner and Claire Fraser-Liggett, also of TIGR, relied on known biology to search T. parva’s genome for potential vaccine proteins. First, scientists know that immunity to the parasite, and thus East Coast fever, emerges from immune system cells known as killer T cells. Second, they know that T. parva is an intracellular pathogen–it infects and secretes proteins inside cattle white blood cells, which become malignant. The white blood cell then unwittingly passes small fragments of the secreted parasitic proteins associated with a certain type if its own proteins along to its cell surface. And this is where a vaccine could come in: A vaccine made of the T. parva proteins found on the surface of host cells should trigger an immune response in cattle. Vaccinated cattle would then be protected from the parasite.

To find potential vaccine antigens, the TIGR researchers scanned T. parva’s entire genome for genes that make secreted proteins. In particular, they searched for genes that make a “secretion signal,” a telltale peptide sequence found at the start of secreted proteins. Sure enough, the scientists found some 400 T. parva genes containing the secretion signal. This set of genes provided a starting pool of candidate proteins. Based on further tests, the study’s research team, led by ILRI of Nairobi, Kenya, cloned 55 candidate antigen genes and screened those genes for response by killer T cells taken from cattle immune to East Coast fever. To complement TIGR’s gene selection strategy, ILRI also incorporated a random screen of T. parva DNA for vaccine candidates.

In total, the team found five candidate vaccine antigens. In lab tests, these antigens triggered a response from cattle immune killer T cells. Going a further step further, the scientists inoculated cattle with these antigens and then gave the cattle a potentially lethal dose of T. parva. When compared with control animals, vaccinated cattle showed significantly stronger immune response to the parasite.

“This study is a true milestone,” says Fraser-Liggett, president of TIGR. “It’s one of the first to take advantage of genomic technologies and build a test vaccine using immune killer T cells as a screening reagent.” In addition to TIGR and ILRI, the research team included scientists from: the Ludwig Institute for Cancer Research in Brussels; the Wellcome Trust Center for Human Genetics in Oxford; Sanofi Pasteur in Toronto; the University of Edinburgh; and Merial SAS, an international animal health company. ILRI and Merial have partnered to develop a vaccine against East Coast fever.

By using genomics to understand and fight T. parva, scientists may make advances against related parasites that cause malaria, tuberculosis, and other diseases in which killer T cells also play a role in immunity. What’s more, because T. parva launches a cancer-like illness inside the white blood cells of cattle, it may provide a model system for understanding the mechanics of cancer biology.

But for Nene, who was born in Kenya and worked at ILRI for 15 years before coming to TIGR in 2001, the march against East Coast fever is significant reward, itself. “This disease takes an enormous toll on the local society and economy of rural areas across eastern and central Africa, including Maasai and other pastoral communities,” he says. In particular, East Coast fever kills cattle kept by families trying to rise out of poverty. If researchers are successful, Nene notes, the entire region will have new reason to hope for a better life. Evans Taracha, ILRI project leader, also highlights the importance of strategic research partnerships to overcome this and similar diseases.

TIGR’s portion of the PNAS study was funded independently by TIGR and by sub-contract from the Animal Health Program of the United Kingdom Department for International Development, with previous contributions from J. Craig Venter and the ILRI for the T. parva genome project.

ILRI wins two top awards

Posted on February 16, 2006 by ILRIComms

ILRI vaccine developers won an award for Outstanding Scientific Article. Another ILRI team conducting research on savannah ecosystems shared an award for their innovative collaboration with Maasai landowners in Kenya.

Scientific Recognition

Each year, the Consultative Group on International Agricultural Research (CGIAR) recognizes the scientific contributions of the 15 agricultural research centres it supports through its Science Awards, presented at its Annual General Meeting (AGM), held each year in December.

At the CGIAR’s AGM held in Washington DC at the end of last year, scientists from ILRI and The Institute for Genomic Research (TIGR) picked up the award for ‘Outstanding Scientific Article’ for their paper, published in the top scientific journal Science, ‘Genome Sequence of Theileria parva: a Bovine Pathogen that Transforms Lymphocytes’. The team, led by Malcolm Gardner of TIGR, received a cash prize of US$10,000, which is being donated to fund travel for staff and students to attend conferences in this area.

The paper’s second author, ILRI scientist Richard Bishop, said: “We are delighted to receive this award. Our multi-partner collaboration and recent discoveries illustrate that African science is forging ahead – we are collaborating with world-class players and producing world-class science right here in Africa, for Africa.”

Innovative Collaboration with Civil Society

The CGIAR also recognizes the contributions of innovative collaborations between CGIAR-supported centres and Civil Society Organizations (CSOs) through its ‘Innovation Marketplace Awards’. This year, 46 CSOs were invited to participate at the CGIAR Innovation Marketplace to showcase their collaborative work and share experiences.

ILRI’s collaboration with the Kitengela Ilparakuo Landowners Association (KILA) was one of four collaborations to win a Judges’ Award with a cash prize of US$30,000, to use for further collaborative work. ILRI has been collaborating with the Maasai of Kitengela Plains, located next to Nairobi National Park, in Kenya, since 2002. They have devised means to ensure that people, livestock and wildlife can live in harmony and have lobbied government to reduce fencing to allow the annual migration of wildlife though the Kitengela Plains, thus helping to prevent conflicts between wildlife and people and their livestock. Other collaborators of the program are Kenya Wildlife Service, Friends of Nairobi National Park, The Wildlife Foundation and Kajiado County Council.

The prize award was collected by ILRI’s CSO representative Ogeli Ole Makui and ILRI’s Mohammed Said. Makui said: “This award means so much to us. Our major challenge is to move forward and continue with the collaboration to help the community move forward. The Landowners Association will be using the prize money to fund further collaborative work.

ILRI scientist Simon Graham wins international ‘Promising Young Scientist’ award

Posted on February 6, 2006 by ILRIComms

Young scientist receives prestigious award at the Consultative Group on International Agricultural Research (CGIAR)'s annual general meeting.

Simon receives his awardSimon Graham, a veterinary immunologist at the Nairobi-based International Livestock Research Institute (ILRI), was bestowed the ‘Promising Young Scientist Award’ by the Consultative Group on International Agricultural Research (CGIAR) on 7 December 2005 by Ian Johnson, CGIAR Chairman and World Bank Vice President for Sustainable Development. This prestigious award was presented at the annual general meeting of the CGIAR, held in Marrakech, Morocco.

The award went to 33-year-old Graham for his research leading to the development of a sensitive and robust system for screening molecules that cause East Coast fever (ECF), a fatal disease of cattle in sub-Saharan Africa. Graham’s research, based at ILRI’s Nairobi laboratories, may also contribute to ongoing efforts to control tropical theileriosis, a cattle disease which puts 250 million cattle around the world at risk.

During his first post-doctoral position at the Centre for Tropical Veterinary Medicine, Edinburgh, UK, in 1998, he developed an improved rapid screening and production of vaccines against the protozoan parasite Theileria annulata, which is responsible for tropical theileriosis.

In 2000, Graham joined a large multidisciplinary research team at ILRI whose goal is to develop a ‘subunit’ Simon At Workvaccine against the related protozoan parasite Theileria parva. (Subunit vaccines are based on molecular bits of parasites rather than whole parasites.) T. parva causes East Coast fever (ECF), which costs 11 countries of eastern, central and southern Africa US$300 million a year. ECF puts 28 million cattle at risk and annually kills 1 million animals, 90 percent of which are kept by poor dairy farmers and herders. There is a high demand from poor livestock owners for a cheap, effective, safe and easy-to-deliver subunit vaccine against this devastating disease of cattle.

Simon Graham and his ILRI team are working in collaboration with several centres of excellence, including the veterinary pharmaceutical giant Merial and a leading human vaccine research group at the University of Oxford, UK, to evaluate the ability of these molecules to protect cattle against ECF. Initial results are encouraging—there appears to be a significant association between an animal’s induction of killer T-cell responses and its levels of protection against development of disease. Graham’s results have within a short space of time had a major impact in moving the research close to its ultimate goal of producing a vaccine that will sustainably control not only ECF but also tropical theileriosis. The vaccine candidates identified by Graham have been filed with the US Patent & Trademark Office and the research is now being prepared for publication in the prestigious journal Proceedings of the National Academy of Sciences (PNAS).

Research breakthrough against cattle killer

Posted on July 25, 2005 by ILRIComms

Innovation, capacity building and partnerships to combat a deadly African cattle disease are in the news. This month, ILRI's East Coast fever research is featured in two top journals – Science and the Journal of International Development. On 1 July 2005, America's leading scientific journal Science reported on the genome sequencing of a deadly parasite, Theileria parva, which causes East Coast fever (ECF), an infectious tick-borne disease that kills two cows every minute in Africa. This ground-breaking research was led by scientists at the International Livestock Research Institute (ILRI) in Nairobi Kenya, and The Institute for Genomic Research (TIGR), based in the USA. In addition to advancing research into parasitic livestock diseases, this research will also be valuable to scientists studying human malaria and cancers. The ECF project is also of great interest to international development practitioners and policymakers. An article published in the July edition of the Journal of International Development by James Smith of Edinburgh University uses the ECF project as a case study example of how institutional research and development is changing. The old model 'technology-led' projects, often criticised for failing to deliver effective and affordable products downstream, is being replaced with new model partnerships that have innovation and capacity building built in and that aim to deliver demand-led products of benefit to the poor in developing countries. Smith describes the ECF project as 'a potentially new model of… research and development partnership' which is an example of “a more ‘complete’ approach to innovation”. The ECF project has many partners and a very clear product focus. The project builds capacity in new ways, as those involved are forced to break out of their traditional boundaries. Scientists who were interviewed felt the project was encouraging them to think in new ways – like farmers and like businesspeople. There are many examples of 'good' technologies still sitting on shelves because scientists failed to consider the needs and circumstances of the end users of the technologies, such as whether the product would be accessible and affordable to farmers. International development professionals and donors are becoming increasingly focused on capacity building, partnerships, innovation systems and, ultimately, the delivery of tangible results, including products, as integral parts of R&D activity. There is a shift away from projects that could be described as 'research for the sake of research' to demand-led research, operated by many partners as a collaborating network that accomplishes a specific goal. John McDermott, ILRI’s Deputy Director General – Research said: 'The ECF Project illustrates ILRI’s new modus operandi, which generates innovation through strategic partnerships. Each partner is doing what they are best at – with the shared goal of delivering an effective and affordable vaccine for East Coast fever that will ultimately benefit millions of small-scale farmers in Africa.' There are lessons to be learned and the ECF project experience looks likely to be scrutinised further to gain more insights into new ways of doing R&D for greater benefits to the world's poor. Smith concludes: 'The East Coast fever vaccine project does appear to offer a new approach to prioritizing research and design, building capacity, and eventually producing an efficacious product. It does appear, however, that the positive spin-offs from the approach may not have been pre-planned but that the approach was shaped by a combination of the contingencies of vaccine production and the realities of institutional R&D in Kenya. The trick will be to identify exactly what makes this approach successful…'.

Biosciences for development

Today the spotlight is on European partners in livestock biosciences for development.
European donors and research institutions working in partnership with ILRI and other CGIAR Centres to speed up agricultural development in poor countries will be highlighted at a breakfast meeting at the 2005 World Bank Sustainable Development European Forum entitled ‘Managing Ecosystems and Social Vulnerabilities in the 21st Century: Towards a More Secure World’, to be held in Paris on 14-15 June 2005. The Forum provides an opportunity to update European bilateral donors on the strategy and work program for the World Bank’s Environmentally & Socially Sustainable Vice Presidency. A significant portion of the agenda is reserved for in-depth, issues-based break-out sessions.

Examples of ILRI projects with European partners are summarized below.

Saving Africa’s unique indigenous cattle breeds critical to its poorest people
In 1998, with funding from Ireland Aid and other European donors, the Africa-based International Livestock Research Institute (ILRI) teamed up with Trinity College, Dublin, to analyse the genetic diversity of indigenous African cattle populations. This project completed molecular diversity datasets from the two centres, unravelled the genetic make-up of African cattle and identified priority cattle breeds for conservation or utilization for the benefit of the farmer communities. The project also helped nations develop strategies for conserving these animals and broadening their use. The project supported evidence that the African continent was a likely center of origin of cattle pastoralism. The latter award-winning research, published in the leading research journal Science, raised awareness of the genetic wealth of Africa’s indigenous cattle populations. African countries are now taking steps to conserve, characterize and make better use of them.

A public-private partnership for technological innovation against a lethal African cattle disease
The East Coast fever vaccine project is an initiative funded by the UK’s Department for International Development (DFID) to design and disseminate a bio-engineered vaccine against a parasite that kills cattle across eastern, central, and southern Africa. A complex set of partnerships between public and private sectors across several continents, including the International Livestock Research Institute (ILRI), in Kenya, the Ludwig Institute for Cancer Research, in Belgium, and the University of Oxford, UK, has played an important role in moving the science forward. The multinational veterinary pharmaceutical company Merial, headquartered in France, is helping to produce the vaccine for trial and will be responsible for the delivery of the vaccine among poor countries. A high degree of complementarity exists between the major partners. ILRI has reached an advanced state of research on the protozoan parasite that causes East Coast fever, bovine immunology and the economic impacts of the disease. Merial produces the vaccine candidates and has been working with Oxford on novel delivery system with potential spin-offs for other human and veterinary vaccines. The project is an example of conceiving and funding a ‘system of innovation’ within the CGIAR, one which cuts across research institutions in new ways, building capacity across the widest possible spread of partners, including NARS.

Conserving a unique genetic resource and way of life among Ankole pastoralists in East Africa
In late 2003, with funding from Austria, scientists from the Africa-based International Livestock Research Institute (ILRI) and the BOKU University of Natural Resources and Applied Life Sciences, in Austria, launched a project to identify indigenous selection criteria and genetic diversity in African longhorn Ankole cattle. The results of this project will improve and sustain the livelihoods of poor Ankole cattle keepers in the four East African countries where these unique cattle are found: Uganda, Burundi, Rwanda and Tanzania. Specifically, the project is facilitating community-based delivery of technical interventions that are genetically improving this breed to meet the needs of their pastoral owners. In the process, the project will help the pastoral communities sustain their environment and culture as well as the genetic diversity of their breed. Indigenous knowledge of animal husbandry and breeding are being captured, as well as selection criteria used by the pastoralists to assess intangible values of their unique Ankole genetic resources.

Development of a second-generation anti-tick vaccine
In late 2004, the Swiss Centre for International Agriculture (ZIL) began funding a project conducted jointly by the Swiss Tropical Institute (Basel), Pevion Biotech (Bern), and the International Livestock Research Institute (ILRI, Nairobi), to develop an anti-tick vaccine to control ticks and tick-borne diseases of tropical cattle. Current tick-control methods rely on regular treatments of animals with acaracides, which kill the ticks. Development of an anti-tick vaccine is one of the most promising alternatives to chemical control, being much safer for the environment and human health. The only commercial vaccine against ticks currently on the market, based on a hidden tick-gut antigenic molecule, requires a series of inoculations to boost the vaccine’s effectiveness. This project is developing a novel antigen-delivery system for use in cattle using virosomes. The aim is to improve the efficiency, handling, user friendliness and cost of the existing vaccine for smallholder farmers. The technology platform developed for the new vaccine may be applied in future against a range of livestock diseases.
