[Animal reservoir hosts of Trypanosoma brucei gambiense in Zaire: trypanosome infections in two foci in Bas-Zaire].
The prevalence of Trypanosoma spp. infections in domestic animals was estimated in a forest (Boma) and a savanna (Kimpese) sleeping focus in Bas-Zaire. The miniature anion-exchange centrifugation technique was used to determine the infection rates with T. congolense, T. vivax and T. brucei spp. in 505 animals. T. congolense predominated in both foci with the highest prevalence in pigs (76.2%), followed by sheep (31.3%), dogs (30.6%) and goats (7.4%). T. vivax was seen only on two occasions. In the forest zone, T. brucei spp. infections were frequent (pigs 16.5%, sheep 6.2%, dogs 3.4%, goats 1.1%) in contrast to the savanna area where only one T. brucei spp. infection was diagnosed. Twenty five primary isolations of T. brucei were done using different isolation and stabilization approaches. Isolates and stocks await behavioural, biochemical and molecular biological identification to discriminate T. b. brucei and T. b. gambiense of domestic animal origin.
