Conteúdo: | The antibody response to louping-ill virus vaccine was examined in mice infected with Try- panosoma brucei and T congolense, and in Ethiopian cattle experimentally infected with T. brucei, T congolense and T vivax. In mice the antibody response was completely supp- ressed, while in cattle infected with T congolense and T vivax the antibody response to the vaccine was only 10 per cent that of uninfected animals. In contrast, the response of cattle infected with T brucei was not significantly reduced, and this was attributed to their relatively light and transient parasitaemias. Trypanocidal chemotherapy (diminazine acetu- rate) administered on the same day as vaccination largely restored  the competence of the immune response of both mice and cattle infected with T congolense. The us eof such drugs should be considered when cattle are vaccinated in trypanosome endemic areas.
