Une équipe internationale de chercheurs a identifié deux gènes qui ont un rapport avec les résistances contre la trypanosomiase. La maladie est provoquée par des parasites unicellulaires du groupe des trypanosomes, qui sont transmis par la mouche tsé-tsé, et elle occasionne des dommages estimés à 4–5 milliards de dollars US par an. Ce sont particulièrement les éleveurs de bovins vivant dans ce qui est appelé la «ceinture tsé-tsé» de l’Afrique, qui va du Sénégal à la Tanzanie et du Tchad au Zimbabwe, qui sont particulièrement touchés.
