Trypanosoma musculi infection in the CBA/N mouse.

The infection of B-cell deficient CBA/N mice by Trypanosoma musculi resulted in a higher parasitaemia, delayed recovery, and a defective antibody response (IgM and IgG1). CBA/N mice were thus less efficient than CBA/J in controlling the infection. These results indicate that B-cells are involved in the immunological control of this parasite.
