title: The composition of the Trypanosoma brucei subgroup in nonhuman reservoirs in the Lambwe Valley, Kenya, with particular reference to the distribution of T. rhodesiense.
abstract: Identification by means of the blood incubation infectivity test (BIIT) of 159 Trypanosoma brucei subgroup strains recently isolated from non-human hosts in the Lambwe Valley, Kenya, has defined the distribution in these hosts of both T. brucei and T. rhodesiense in an endemic sleeping sickness area. The presence of a small third group strongly suggestive of a population intermediate between these two species has also been revealed for the first time.Repeated testing of a number of these strains has shown marked consistency in the results. Strains identified by the BIIT as T. rhodesiense have been isolated for the first time from a reedbuck and a sheep. There appears to be direct relationship between the local prevalence rates of T. rhodesiense in non-human reservoirs and the incidence of sleeping sickness in man.
