Peripheral blood leukocyte subpopulation dynamics during Trypanosoma congolense infection in Boran and N'Dama cattle. An analysis using monoclonal antibodies and flow cytometry por Ellis, J.A., Scott, J.R., MacHugh, Niall D., Gettinby, George, Davis, W.C.

“…Summary A panel of monoclonal antibodies (MoAb) with specificities for bovine leucocyte subsets were used in conjunction with routine haematological procedures to analyse sequential changes in peripheral blood leucocyte populations during the course of tsetse fly‐transmitted Trypanosoma congolense infection in trypanotolerant N'Dama and trypanosusceptible Boran cattle. Subsequent to the first parasitaemic wave, the N'Dama cattle maintained packed cell volumes (PCV) above 22 and lower levels of parasitaemia than Boran throughout the 160 days of the experiment. …”
