Abstract
Blood was collected into heparin (10 units/ml) from each of four H. brucei hindei and three P. habessinica jacksoni, shot in the field. One ml of this heparinized blood was inoculated into individual splenectomized SA mice. Blood smears from these mice were examined for 30 days, but no evidence of transmitted infections was detected. Small numbers of Rhipicephalus distinctus ticks were collected from three H. brucei hindei and three P. habessinica jacksoni. Engorged nymphal ticks were molted to adults and these ticks, together with those collected as adults, were fed for 4 days on the ears of a rabbit prior to dissection of their salivary glands (Martin, Barnett, and Vidler, 1964, Exp. Parasit. 15: 527). Two out of eight ticks dissected showed evidence of salivary gland infection: no parasites could be identified but in each case a small number of acini showed markedly hyperplastic nuclei. R. distinctus, which is a host-specific tick, can probably therefore be considered as the vector of B.thomasi in H. brucei hindei and P. habessinica jacksolli in Kenya. This paper represents the first record of B.tho11lasi from Kenya and from P. habessinica
