Research at BecA-ILRI Hub supports vaccine development policy in Kenya

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.

Supporting African-led agricultural research to drive economic growth – Part 1

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.

Exploring biological control of crop disease through plant-pest interactions

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.

Cassava, flies and viruses: studying the role of whiteflies in cassava disease at the BecA-ILRI Hub

By William Sharpee, postdoctoral fellow, North Carolina State University

Gabriela Chavez and William Sharpee

Cassava is an important food crop for millions of people in sub-Saharan Africa, but unfortunately this crop is facing a decline in production across the continent due to Cassava Mosaic Disease (CMD). I came to the BecA-ILRI Hub in August to work on a project funded by the National Science Foundation Partnerships for International Research and Education (NSF-PIRE) to analyze the evolution of the viruses that cause this disease.

The purpose of this project is to understand how African cassava mosaic virus (ACMV) and East African cassava mosaic virus (EACMV), the causal agents of CMD, evolve during vegetative propagation of infected cassava plants versus being transmitted via whiteflies. It is our goal to understand how these viruses evolve in order to develop strategies that will hinder the development of more virulent strains and thus prevent future outbreaks of CMD.

When I first arrived in Kenya, I travelled to the shores of Lake Victoria in the western part of Kenya to collect whiteflies for the establishment of a colony at the BecA-ILRI Hub. This was a good opportunity to interact with local farmers and see the devastating effects that this disease has on cassava production in Kenya. Once the individual whiteflies were collected we set up a room dedicated to establishing a colony to be used in future experiments.

Because multiple species of whiteflies exist, my colleagues and I have focused our efforts on understanding the genetic make up of the colony to ensure that we have a single species for our experiments. Additionally, we established procedures for the propagation and growth of cassava in the greenhouse. We continue to lay the groundwork for pilot experiments that will act as the basis for our future work.

I am excited to be a part of this project and the BecA-ILRI Hub community. I am grateful for everyone’s support and input and look forward to great discoveries in the future.

Kenyan farmers reap rewards of the amazing Brachiaria grasses

K24 Journalist Violet Otindo highlights the changing fortunes of dairy farmers using Brachiaria grasses to feed their animals in Kenya.

YouTube Preview Image

Preliminary data from dairy farmers participating in on-farm evaluations of Brachiaria grasses in Kenya shows that the nutritious grasses contribute to increased milk production.

The on-going research program on Climate-smart Brachiaria Grasses to Increase  Livestock Production in East Africa conducted by the BecA-ILRI Hub in collaboration with the Kenya Agricultural and Livestock Research Institute (KALRO); Rwanda Agriculture Board (RAB) ; International Center for Tropical Agriculture (CIAT), Colombia; and Grasslanz Technology Limited, New Zealand has engaged smallholder farmers in cultivating the grasses as major livestock feed sources and as a source of household cash income through the seed production.

The Swedish funded program has been successful in, together with farmers, identifying best bet varieties for different agro-ecological regions and creating awareness among the farmers, researchers, extension agents, policy makers and politicians on the significance of Brachiaria grasses to support a growing dairy industry. Through the project, farmers have discovered that the Brachiaria grasses not only preferred by animals but  also grow better than most forage in marginal soils of semi-arid and sub-humid environments that are common in most of Sub-Saharan Africa.

In this four minute video, K24 journalist Violet Otindo talks to Albanus Nduva from Kanzalu village of Machakos County in eastern Kenya, one of the 1200 farmers in Kenya who have been involved in participatory on-farm evaluations of Brachiaria grasses as pasture and recording the milk production data Otindo also gets insights from BecA-ILRI Hub scientist Sita Ghimire who leads the program and Donald Njarui from KALRO, Kenya as to why Brachiaria grasses are good for the environment.

Welcome home Brachiaria! Home coming of Africa’s “super” grass

“The hitherto overlooked Brachiaria grasses have returned home to Africa and have been warmly embraced by smallholder dairy farmers in eastern Africa.”

Presenting a paper co-authored by nine scientists from seven institutions including the BecA-ILRI Hub, Dr Brigitte Maas from International Center for Tropical Agriculture (CIAT) gave an overview of the research, successes and challenges of adopting improved Brachiaria hybrids Mulato and Mulato II in the African context during the 6th All Africa Conference of Animal Agriculture in Nairobi on 27 October 2014.

Brachiaria grasses have higher nutrient content than most commonly used forages. They are adapted to drought and low fertility acidic soils. These grasses are good for the environment as they enhance nitrogen use efficiency, sequester carbon, and reduce greenhouse gas emission and ground water pollutions. These attributes make Brachiaria one of the most widely cultivated forages in South and Central America, and Australia where they have been shown to increase milk and meat yields in cattle.

Re-introducing Brachiaria grasses to their native home
Despite the fact that they are native to Africa and that they occur plentifully across many regions of sub Saharan Africa, these grasses are yet to be explored and fully utilized as forage on the continent. However, thanks to the implementation of a Swedish funded research program “Climate-smart Brachiaria grasses for improved livestock production in East Africa” which is led by BecA-ILRI Hub in partnership with CIAT; Kenya Agricultural and Livestock Research Organization (KALRO); Rwanda Agriculture Board (RAB); and Glasslanz, the anonymity of these “wonder grasses” is coming to an end. The heightened publicity of the importance of Brachiaria grasses and as a strategy to mitigate the effects of climate change has resulted in substantial interest in these grasses among farmers, researchers and policy makers across the continent.

While improved varieties developed in Latin America are being tested in Africa, challenges from pests and diseases have been observed on these imported varieties. The grassed developed in South American conditions have already been observed to be vulnerable to spider mites; sorghum shoot fly, and a number of fungal diseases that are currently in the process of identification. This has necessitated a deeper investigation into locally available diverse genetic resource in Africa to identify the pest and disease resistant varieties.

Finding the best local varieties for the African context

Since Africa hosts a high genetic diversity of Brachiaria, the way forward would be the utilization of this untapped genetic resource to breed varieties that are suitable to the African context. The BecA-ILRI Hub-led project is exploring local ecotypes and gene bank accessions of African origin for drought tolerance, pests and disease resistance and biomass yields. This program consists of four main components – evaluating Brachiaria genotypes for drought tolerance and adaptation to marginal soils; evaluating varieties for biomass production, animal nutrition (including feeding experiments) and seed production; identification and use of phytobiomes for potential agricultural applications as bio-fertilizers, bio-pesticides and bio-yield enhancement agents; and the building the capacity of African scientists to conduct research on Brachiaria grasses.

This collaborative research effort is giving renewed hope to millions of smallholder livestock farmers across eastern Africa who operate smallholder crop-livestock mixed farms on less than 10 ha and are at pains to increase their production in a set up where natural grazing is limited or no longer available

Growing healthier sweetpotato – research to combat sweetpotato weevil

YouTube Preview Image

Lydia Wamalwa is a molecular plant scientist with the International Potato Center (CIP) whose research in Kenya is hosted at the BecA-ILRI Hub in Nairobi. Lydia and her colleagues at CIP are working to develop sweetpotatoes that will fight off the sweetpotato weevil without using pesticides.

The sweetpotato is an important food crop in developing countries which account for 95% of the over 105 million metric tons produced each year globally. Its ability to grow in marginal conditions and with little labor and inputs, makes the sweetpotato a source of resilience in food and nutritional security to smallholder farmers. Not only is sweetpotato nutritious to humans (contains vitamin A, B, C and E) but it also provides inexpensive, high-protein fodder for animals.

Unfortunately production of this highly adaptable food crop faces a major threat from the sweetpotato weevil, which often causes losses of 60% – 100% during periods of drought. In this two and a half minute video, Lydia Wamalwa talks about the ongoing research to develop sweet potato resistance to sweetpotato weevil which is supported by the World Bank.

The International Potato Center is among the hosted members of the CGIAR consortium which contribute valued crop biosciences capacity to the BecA-ILRI Hub. Other members of the CGIAR consortium whose research is hosted at the BecA-ILRI Hub include International Institute of Tropical Agriculture (IITA) and the International Rice Research Institute (IRRI).

Celebrating International Women’s Day at the BecA-ILRI Hub

While the International Women’s Day is a time to celebrate the enormous contribution made by women to the economic, political and social development of their country and communities, it is also important to reflect on the hurdles that prevent them from achieving their full potential.

The emphasis of this year’s theme, “Equality for women is progress for all” is that the capability of women to participate fully in society without discrimination and with the necessary support is essential to economic and social progress. Sadly, across the globe, much talent remains unexploited as girls turn away from science and technology (S&T) careers and as women in S&T become discouraged by discriminatory treatment. (UNESCO, 2007).

The UNESCO Institute for Statistics places the percentage of female researchers in Africa at only 34.5%. Patriarchy, stereotyping of female roles and reproductive roles are some of the barriers preventing women from fully participating in S&T. Still, many women continue to rise above the odds and make their mark in the science world and at the BecA-ILRI Hub, we recognize four such women whose pursuit of their dreams is backed by their passion to make food and nutritional security in Africa a reality.

Gerardine Mukeshimana from Rwanda is a post-doctoral scientist in plant molecular biology currently working on a project to develop tools that will be used to control the spread of aphid-transmitted virus diseases in the common bean.

I never felt discriminated against or pigeon-holed by my family. I was fortunate to go to a science based high school in Rwanda. The government in Rwanda generally supports the study of science and technology, and there are programs to encourage high school girls to be leaders in whatever sphere they choose. I must admit that in college, there were very few girls in my class but I never felt discouraged or out of place.

The support I get from my husband has ensured that family responsibilities never come in the way of my career advancement and as a result I have had many achievements. I have worked in various capacities in the Ministry of Agriculture in Rwanda; I was recognized by the United States Agency for International Development’s Board for International Food & Agriculture Development (BIFAD) for my significant contributions to the breeding of the common bean for drought tolerance and disease resistance; and I received a Norman Borlaug Leadership Enhancement in Agriculture Program (Borlaug LEAP) fellowship for my contributions to breeding of the common bean.

I would say in pursuing my career, I have always had the full support of my family and country.

Martina Kyalo from Kenya is a research Assistant at the BecA-ILRI Hub responsible for capacity building including training and technical support to visiting scientists and students. Martina is also pursuing her PhD in Molecular Virology.

I used to think science was a hard field but that I was up to the challenge. In my Masters’ class, I was the only female student to complete her degree course, which made me very proud of myself. Currently, I am in an environment where opportunities are open to both men and women on an equal basis which makes things very competitive and rewarding.

Being a mother has meant that l have had to lose out on many opportunities to better my career. These were mostly opportunities that would require me to be away from home for long periods of time and I wanted to raise my daughter first. However, my family is very supportive, my daughter is older and now understands the commitment involved in a science career, so I can go after some of those openings.

So far, I would say I am doing very well. I have been invited to regional science meetings and have been able to contribute to the progress of scientists from different institutions. I also received a four year PhD scholarship which is allowing me to make up for the lost opportunities!

Helen Nigussie is a PhD Student (Animal Breeding and Genetics), Haramaya University, Ethiopia. She was also the recipient of an Africa Biosciences Challenge Fund Fellowship at the BecA-ILRI Hub.

Both men and women discouraged me at the beginning of my career since they considered science at the tertiary level to be a preserve for men. However, I was very determined and did not let anyone put me down. For me it has taken hard work and determination to pursue the career of my dreams.

My family commitments have never really stood in the way of my career, but it is not easy to be successful in science especially for women. We are responsible for both productive and reproductive activities. Family support and understanding is very important. I have enjoyed very strong support from my family and especially from my husband.

Being female has never hindered me from going after what I want. I believe I can achieve my dream for both education and personal life. I have a lovely family who are the backbone of my successes, and I will soon get my PhD in Animal breeding and genetics!

Cécile Annie Ewané is a senior lecturer at the University of Yaoundé I and an associate researcher at the African Research Centre on Bananas and Plantains (CARBAP) in Douala, Cameroon. She was also the recipient of an African Biosciences Challenge Fund Fellowship at the BecA-ILRI Hub.

Although science is considered ‘a male domain’ by many societies, I have never experienced any discouragement from pursuing a career in scientific research. My specialization is agricultural research and I feel strongly that as woman, I must do something about food security. In Sub-Saharan African countries and in Cameroon in particular, women are very important players in agriculture.

Many years ago at an international seminar, I was the only woman delegate and no foreign delegates came to discuss and exchange ideas with me during the coffee break as they were doing with my male colleagues. I felt so alone and that day, I asked myself if I was really in the right place. I now know what to do in such cases – take the initiative and start the conversation! I have no problems at work even though most of colleagues are men. I think that with time, they got used to having a lady among them.

My family commitments have not reduced my capacity to meet my potential. Although it is sometimes difficult to balance career and family life, I have done my best, and received the full support of my family. Through my hard work, family support and the Grace of God, I would say that I am a fulfilled, family woman and an accomplished scientist.

I attained a PhD and have just been promoted to senior lecturer at the University of Yaoundé. I am the Associate Chief of the Laboratory of Phytoprotection and Valorization of Plant Resources of the Biotechnology Center (Nkolbisson) of Yaoundé, where I try every day to advance the quality and the level of research.
