Prevalence of T. b. rhodesiense in tsetse through incorporation of dissection/microscopy and PCR data.

All fly midguts where trypanosomes were observed by microscopy were analysed by PCR., Dispos is the proportion of flies examined that were positive by dissection/microscopy, PCRpos is the proportion of dissection/microscopy positive flies that were also positive by PCR for T. brucei s.l., PTbr/Tbb is the ratio of T. b. rhodesiense to T. b. brucei and Pmat is the proportion assumed to mature to the salivary glands. CI are 95% confidence intervals.
