Table 5. Prevalence of T. b. rhodesiense by dissection/microscopy, PCR and model inference.

	Prevalence of T. b. rhodesiense (%)
	Dissection/microscopy	PCR	Model
G. swynnertoni	0 (0–0.085)	0.010 (0–0.054)	0.0064
G. pallidipes	0 (0–0.18)	0.0089 (0–0.059)	0.00085

Prevalence of T.b.rhodesiense in the two main tsetse species in Serengeti National Park was analysed by dissection/microscopy and model inference. Dissection/microscopy cannot differentiate T. brucei brucei and T. b. rhodesiense so is a measure of T. brucei s.l. prevalence. Ninety-five percent confidence limits are shown in parentheses.
