By Jane Githinji, assistant director of veterinary services, Kenya and ABCF alumnus

Jane githinjiAs head of the virology laboratory at the Central Veterinary Laboratories in the Directorate of Veterinary Services (DVS) in Kenya, my responsibilities include laboratory surveillance, and confi rmation and reporting of animal viral diseases. My reports form the basis upon which disease control strategies are developed. It is, therefore, of the utmost importance that these reports refl ect the true picture of the disease situation in the country, from which appropriate disease control policies and strategies can be derived.

Like in most developing countries, poultry farming in Kenya is mainly in the hands of the smallholder rural poor, mostly women and young people, and is usually the only livelihood source for smallholder farmers. Outbreaks of infectious viral diseases that cannot be treated pose a major constraint on poultry production. Vaccination is the recommended method of control for these diseases. But vaccines do not always prevent occurrence of a disease.

The apparent failure of vaccines to protect chicken from infectious bursal disease (IBD) got me interested in understanding the cause of the disease despite prompt vaccinations by farmers (IBD causes immune suppression, making chicken more prone to other infectious diseases). I wanted to improve my understanding of the epidemiology of IBD in Kenya, starting with the comparative molecular characterization of the circulating viruses with the currently used vaccine virus strains.

The facilities available at the central veterinary laboratory are suitable for carrying out basic molecular analysis. However, to undertake more advanced molecular research required to gain a better understanding of IBD viruses circulating in Kenya, I needed access to the facilities at the BecAILR Hub. Under the mentorship of the BecA-ILRI Hub scientists, in a very conducive research environment as an ABCF fellow, I learned many skills, including sequence editing and analysis, primer design, scientific paper writing and communicating science to non-scientists. These crosscutting skills will be very useful in improving my diagnostic capacity, and ultimately, scientific data collection for policy development at the DVS.

Based on the feedback and recommendations I gave to the DVS director, I am confident my research findings will form the basis for developing effective IBD control strategies, including diagnosis, vaccination, hatchery surveillance and certification, IBD vaccines registration and vaccine production. Implementation of such strategies will have far reaching impacts on poultry production, poverty alleviation, nutritional security, economic empowerment for women and young people, and self-employment. Reducing antimicrobial residues in poultry products will also contribute to a reduction in antimicrobial drug resistance in humans.

With my newly acquired skills, I will be able to contribute more to livestock research: science, technology and innovation. I am a better mentor to young people, a better leader and manager, a more fulfilled person, and, above all, an asset to my country. My time as an ABCF fellow marked the beginning of what I believe will be a journey full of discoveries, networking, research development and fulfilment.

Investigating the role of bushmeat in the transmission of zoonotic diseases in Tanzania

Research conducted by the Biosciences eastern and central Africa-International Livestock Research Institute (BecA-ILRI) Hub in collaboration with National Health Laboratory of the Tanzania Ministry of Health and Social Welfare; Nelson Mandela African Institution of Science and Technology (NM-AIST); Sokoine University of Agriculture; Tanzania National Parks; Tanzania Wildlife Research Institute; Frankfurt Zoological Society; and Pennsylvania State University.

An outcome of the BecA-ILRI Hub’s Swedish funded initiative to strengthen infrastructural and human capability at NM-AIST, was the awarding of a grant to the institution by the US Defense Threat Reduction Agency.

The NM-AIST School of Life Sciences and Bioengineering and a consortium of partners including the BecA-ILRI Hub received a grant to investigate the role of bushmeat in the transmission of six pathogens between animals and humans in Tanzania.

An interdisciplinary and multi-institutional team of scientists from Tanzania, Kenya and the US are using state-of-the-art techniques to map the distribution of anthrax, ebola, marburg and monkeypox viruses as well as Brucella and Coxiella in bushmeat in Tanzania. The team assesses the biological risk and potential for impact on human health from these diseases.

The BecA-ILRI Hub provides capacity building, expertise and technology for the microbiome component of the project using the genomics platform. During a week-long workshop facilitated by the BecA-ILRI Hub at NM-AIST, Francesca Stomeo provided training on the theory and practice of the genomics pipeline to be used in the project.

Scaling up the use of Brachiaria grass as a key forage in Africa

Research implemented in Kenya and Rwanda by the Biosciences eastern and central Africa-International Livestock Research Institute (BecA-ILRI) Hub and national partners — the Kenya Agricultural and Livestock Research Organization (KALRO) and  Rwanda Agriculture Board (RAB)

On-farm evaluations in Kenya and Rwanda have confirmed that the use of Brachiaria grass extends forage availability for livestock by up to three dry months. These evaluations also confirmed previous observations of increases in milk production and weight when cattle are fed on Brachiaria grass. Over 6,000 farmers in both countries are growing the four best-bet Brachiaria varieties (Basilisk, MG4, Piatã and Xaraés), which were identified through the use of a participatory approach with key stakeholders. These varieties are being concurrently scaled out in Kenya and Mali by the Accelerated Value Chain Development (AVDD) dairy project, funded by the United States Agency for International Development (USAID) Feed the Future Initiative. There is growing interest and a push to adopt Brachiaria grasses in other countries including Botswana, Cameroon, Mozambique, Namibia and Somalia.

This research has identified potentially beneficial bacteria that occur naturally within the grass (bacterial endophytes). The endophytes could be useful: increasing production of hormones that regulate: plant growth and boost biomass production in Brachiaria; improving soil nutrient solubility and soil fertility; enhancing drought tolerance; and improving the overall health of the grass. These endophytes are currently being evaluated under greenhouse conditions for their ability to confer drought tolerance to Brachiaria.

To ensure the transfer of technologies to national programs, seven researchers from five East African countries were trained on forages biotechnology through the Brachiaria program. After periods of between six and nine months at the BecA-ILRI Hub the NARS researchers returned to their home institutions with transferable skills acquired through the training. An in-depth external review of the program concluded that it has made significant contributions to the improvement of forage availability and livestock productivity in the aforementioned program countries.

AR 2016 reportIn 2016, the Biosciences eastern and central Africa–International Livestock Research Institute (BecA-ILRI) Hub celebrated 15 years as a centre for excellence for agricultural research. Against a backdrop of renewed impetus for innovation in agricultural research for development (AR4D) in Africa, BecA-ILRI Hub and its partners showcased their joint achievements in responding to the Science Agenda for Agriculture in Africa (S3A)— leveraging science in an agriculture-led social and economic transformation. The event also offered us an opportunity to acknowledge our donors, whose support has made these accomplishments possible.

Research facilitated by the BecA-ILRI Hub drives the bioscience innovations that underpin development outcomes. The success of the climate-smart Brachiaria program in developing technologies that are readily adapted by farmers has generated a demand for their scaling-up. Strategic partnerships, for instance with the North Carolina State University (NCSU)—leveraging the human resource of advanced research institutions—have enabled groundbreaking work in tackling the devastating cassava mosaic disease, potentially increasing yields in what is a staple crop for over 250 million people in Africa.

Through the Africa Biosciences Challenge Fund (ABCF) fellowship program, up and coming research fellows from national agricultural research systems (NARS) have contributed to the formulation of evidence-based agricultural policies. For instance, seminal work on maize and food safety has provided a clearer picture of the interventions required throughout the value chain in Rwanda and research into chicken vaccines has supported the elaboration of policies guiding the production of vaccines for infectious bursal disease in Kenya. Moreover, the establishment and support of communities of practice (CoPs) for ABCF alumni has enabled the development of a comprehensive regional approach to the tackling of key livestock and crop research challenges.

In step with technology advances, the BecA-ILRI Hub launched the Integrated Genotyping Service and Support (IGSS) platform to enhance efficiency and precision in plant and livestock breeding, as well as quality seeds assessment. In research led by the International Maize and Wheat Improvement Center (CIMMYT), application of this new technology has improved understanding of the genetic basis for resistance to maize lethal necrosis (MLN). The ongoing upgrading of the BecA-ILRI Hub’s technology platforms is fast-tracking research within the regional NARS and reducing the need for scientists to leave Africa to do their work.

Working to shape to continent-wide processes, BecA-ILRI Hub staff joined CGIAR research scientists, policymakers, and representatives of higher education networks and the private sector at a workshop to develop the concept of the the African Agricultural Research Programme (AARP). AARP is an initiative led by the Forum for Agricultural Research in Africa (FARA) to strengthen the continent’s agricultural research systems for increased productivity, profitability and sustainability. As part of our 2018–2023 strategy, the BecA-ILRI Hub will seek to play a leading role in the application of and support for biosciences in the region. A landscape survey confirmed the comparative advantage of the BecA-ILRI Hub as an important regionally-valued bioscience facility. It identified opportunities to enhance our role in helping set the bioscience agricultural research agenda, as well as an advocate for the government funding of NARS work in bioscience technologies and services.

The coming year will, therefore, be characterized by engagement with key stakeholders to guide the development of our new five-year plan. We remain committed to helping Africa use biosciences as a means of transforming agriculture, bridging the gap between population growth and agricultural productivity on the continent. To the readers of this report, we hope you will accompany us on this grand AR4D journey in Africa. To our many partners and donors, thank you for your support.

Aphids, leafhoppers and whiteflies are responsible for the spread of diseases causing significant crop yield losses globally. On 5 July 2017, the Biosciences eastern and central Africa-International Livestock Research Institute (BecA-ILRI) Hub hosted a symposium to explore ways in which the knowledge of plants, disease-causing organisms and their vectors can be used to combat devastating crop diseases in Africa.

In sub Saharan Africa, the aphid-transmitted bean viruses—bean common mosaic virus (BCMV) and bean common mosaic necrosis virus (BCMNV)—cause up to 100 percent losses for smallholder bean farmers. Growers of cassava—a staple food for over 250 million people— experience losses of up to 23 million tonnes annually across Africa due to disease caused by whitefly-transmitted Cassava mosaic viruses.

In the face of increased regulations on the use of pesticides, a better understanding of the plant-microbe-vector interactions could lead to the development of urgently needed bio pest-controls. The July forum brought together researchers from the BecA-ILRI Hub, Kenyatta University, International Institute of Tropical Agriculture (IITA), Auburn University and North Carolina State University based in Africa; and the John Innes Centre (JIC) from UK.

From 19–30 June 2017, the Biosciences eastern and central Africa-International Livestock Research Institute (BecA-ILRI) Hub will host the third edition of the Animal Quantitative Genetics and Genomics annual training workshop. The training is strengthening the capacity of researchers in Africa to apply an in-depth understanding of livestock genetics to the design of livestock breeding programmes.

Early this month (8–12 May 2017) over 250 experts from the public and private sectors in more than 50 countries across the globe gathered in Addis Ababa, Ethiopia to discuss the benefits and potential of livestock during the Global Agenda for Sustainable Livestock (GASL). The increasing demand for animal protein in emerging economies in Africa presents the challenge of sustainably improving livestock productivity while at the same time maintaining genetic diversity.

Since 2012, the BecA-ILRI Hub has been conducting research to improve performance of indigenous goats using their genetic diversity. Working in Cameroon and Ethiopia, the “Harnessing genetic diversity for improved goat productivity” project looked at the genetic adaptation of goat populations in the two countries to environmental challenges including drought and disease.

To Getinet Mekuriaw, an assistant professor at Bahir Dar University in Ethiopia and a visiting scientist at the BecA-ILRI Hub, the key to sustainable development of livestock in Africa is in the optimal exploitation of genetic resources to improve indigenous breeds.

‘We have the evidence of a rich genetic resource in livestock in Africa, and particularly in indigenous goats,’ Mekuriaw said ‘the next step is investing in research that will link this intelligence to the design of trait-focused breeding programs.’

Mekuriaw’s PhD contributed largely to establishing the extent of diversity among indigenous goat breeds in the two countries of interest for the BecA-led research. He also investigated the genetic potential of the goat populations in adaptation, disease resistance, reproduction and hair fibre production.

Strategies to enhance livestock production–including exploiting the natural potential of local breeds–could greatly contribute to the realization of the 2030 Agenda for Sustainable Development through increased agricultural capacity in developing countries.

As part of ongoing research to develop an effective vaccine for East Coast Fever (ECF), I conducted a study on the interactions between the parasites that cause disease and vectors that transmit them. East Coast Fever is a tick-borne disease that kills over 1 million cattle in East, Central and Southern Africa annually, devastating the livelihoods of smallholder livestock farmers. I would like to develop a vaccine that can block transmission of this disease at the vector level.

My quest to apply computational methods to identify potential ECF vaccine candidates however requires a more in-depth understanding of parasite and vector biology, and interaction. A travel scholarship from the BecA-ILRI Hub enabled me attend the 2016, the NIH-Global Infectious Disease Training Program’s Workshop on Biology of Parasites and Disease Vectors. This presented an opportunity to progress my search for a solution to ECF which begun through a fellowship under the Africa Biosciences Challenge Fund (ABCF) program at the BecA-ILRI Hub (October 2014–March 2015).

The workshop took place at Gulu University in Uganda, one of the regional institutions whose capacity has been strengthened by the BecA-ILRI Hub. It was organized by Gulu University in partnership with Yale University and Biotechnology Research Institute-Kenya Agricultural and Livestock Research Organization (BRI-KALRO). It was a good opportunity to share the outcome of my work, build my capacity and network with fellow researchers that share similar interests.

I gained different perspectives to approaching my research. For instance, I learned how  vector physiology, ecology, immunity, evolutionary biology and genetics studies are applied in development of effective disease control strategies. Through group discussions, I got new ideas for future ECF vaccine development studies.

Of course, at the end of the workshop, I gave a brief oral presentation about the BecA-ILRI Hub, and the opportunities available for African scientists to build their research capacity while solving major food insecurity causes such as livestock diseases on the continent.

The Aflatoxin Proficiency Testing and Control in Africa (APTECA) program hosted by the mycotoxin diagnostics platform at the Biosciences eastern and central Africa-International Livestock Research Institute (BecA-ILRI) Hub is contributing to the availability of safe maize on the African market.

The program, managed by the Texas A&M University, USA, was initiated to support the commercial maize milling sector in Kenya through a public-private partnership. Cereal millers which participate in the voluntary program manage aflatoxin risk by improving their quality systems to accurately perform their own tests for aflatoxins in maize flour.

Proficiency testing program

Participation in the APTECA program improves testing accuracy through qualification of the mill’s laboratory analysts; use of working controls with a known level of aflatoxin; routine proficiency testing; and verification of mill results by the ISO accredited Texas A&M AgriLife laboratory housed at the BecA-ILRI Hub.

In 2015, 31 laboratory analysts from commercial mills across Kenya attended training and qualified to analyse maize flour using validated aflatoxin testing platforms. These qualified individuals analyse working control samples twice a week at their respective mills to ensure testing accuracy and results are evaluated using a statistical process control charting technique. Further verification of mills’ aflatoxin test results of finished product occurs at the Texas A&M AgriLife laboratory at the BecA-ILRI Hub and results are sent to the APTECA mills to assist in quality improvement and aflatoxin risk management.

Already, APTECA has hosted five proficiency testing exercises involving 30 industry and public sector laboratories. The companies involved in the project include Osho Grain Millers; Unga Holdings; Alpha Mills; Capwell Industries; Kabansora Millers; Kenblest Group; Maisha Flour Mills; Mombasa Maize Millers; Pembe Flour Mills; Premier Group; and United Millers all from Kenya.

Co-regulation

The APTECA research is part of an effort to explore co-regulation of aflatoxin as a regulatory risk-management policy alternative with the aim of improving food safety and facilitating trade in Africa. Co-regulation involves a government-private sector partnership in regulation that includes statutory or government-backed codes of practice combined with regulatory and industry oversight. A marketing study conducted by the International Food Policy Research Institute (IFPRI) and the Western Michigan University in collaboration with Texas A&M AgriLife explored the impact on sales of marketing products branded with a logo on packages of maize meal stating ‘Aflatoxin Tested Process Verified by APTECA.’ This logo conforms to the East African Community labelling requirements and AgriLife has received trademark approval for it from the Kenya Intellectual Property Institute.

A memorandum of understanding (MoU) with a Kenya regulatory authority, accreditation of the AgriLife laboratory activities by the Kenya Accreditation Service, and training regulatory chemists from six countries and nine agencies has helped lay the groundwork for a regional public-private sector partnership to manage aflatoxin risk and facilitate trade among countries in the Common Market for Eastern and Southern Africa.

A partnership catalyzed by the Biosciences eastern and central Africa-International Livestock Research Institute (BecA-ILRI) Hub to improve testing for aflatoxins in maize flour will feature at a side event during the 7th Africa Agriculture Science Week and the Forum for Agricultural Research in Africa (FARA) general assembly, next week (from 13-14 June 2016).

The partnership brings together the Kenya Cereal Millers Association—which has over ten million customers, including the urban poor—and the Texas A&M AgriLife laboratory which is hosted at the BecA-ILRI Hub. It is enabling millers to accurately perform their own tests for aflatoxins in maize flour, reducing aflatoxin risk and improving food safety for an estimated 16 million Kenyans.

Aflatoxins are a naturally occurring carcinogenic by-product of common fungi that grow on grains and other food crops, particularly maize and groundnuts. Highly carcinogenic, aflatoxins are lethal in high doses, with chronic exposure potentially stunting infant development, blocking nutrient absorption and suppressing the immune system.

Preventing human exposure to aflatoxins involves removing crops with unacceptable aflatoxin contents from both foods and feeds.

Paloma Fernandes, the chief executive of the Kenya Cereal Millers Association, will give a presentation on industry-led approaches to controlling aflatoxin in the country’s food supply chain at the ‘Strengthening systems to optimize agriculture and nutrition outcomes in Africa’ side event.
