Abstract

Two subspecies of Trypanosoma brucei s.l. co-exist within the animal populations of Eastern Africa; T. b. brucei a parasite which only infects livestock and wildlife and T. b. rhodesiense a zoonotic parasite which infects domestic livestock, wildlife, and which in humans, results in the disease known as Human African Trypanosomiasis (HAT) or sleeping sickness. In order to assess the risk posed to humans from HAT it is necessary to identify animals harbouring potentially human infective parasites. The multiplex PCR method described here permits differentiation of human and non-human infective parasites T. b. rhodesiense and T. b. brucei based on the presence or absence of the SRA gene (specific for East African T. b. rhodesiense), inclusion of GPI-PLC as an internal control indicates whether sufficient genomic material is present for detection of a single copy T. brucei gene in the PCR reaction.
