This short (5-minute) film, ‘Battling a Killer Cattle Disease’, produced by the International Livestock Research Institute (ILRI), provides background and context for a recent research breakthrough made at ILRI’s animal health laboratories in Nairobi, Kenya, and at their partner institutions in the UK and Ireland. The research was funded over 7 years in large part by the Wellcome Trust in addition to the Consultative Group on International Agricultural Research (CGIAR).
Trypanosomosis is a wasting disease of livestock that maims and eventually kills millions of cattle in Africa and costs the continent billions of dollars annually.
In 2011, a group of geneticists at these collaborating institutions identified two genes that enable Africa’s ancient N’Dama cattle breed to resist development of the disease trypanosomosis when infected with the causative, trypanosome, parasite.
The team members were able to make use of the latest gene mapping and genomic technologies because they had the genetic systems and experimental populations of livestock in place to do so as these technologies came on stream.
Eventually, these results should make it easier for livestock breeders in Africa to breed animals that will remain healthy and productive in areas infested by the disease-carrying tsetse fly.
The international team that came together in this project is an example of the disciplinary breadth as well as agility needed to do frontline biology today. In this work, the team developed several new research approaches and technologies that were needed to unravel some fundamental biological issues, with likely benefits for many African farmers and herders.
Those interviewed in the film include Harry Noyes, at the University of Liverpool; Alan Archibald, at the Roslin Institute at the University of Edinburgh; Andy Brass, at the University of Manchester; and Steve Kemp and Morris Agaba, at ILRI.
