dc.description.abstract | Background: Studies on the epidemiology of African Animal Trypanosomiasis (AAT) rarely consider the spatial
dimension of disease prevalence. This problem is confounded by use of parasitological diagnostic methods of low
sensitivity in field surveys. Here we report a study combining highly sensitive and species specific molecular
diagnostic methods, and Geographical information system (GIS) for spatial analysis of trypanosome infection
patterns, to better understand its epidemiology. Blood samples from 44 and 59 animals randomly selected from
Teso and Suba districts respectively were screened for trypanosomes using PCR diagnostic assays. Spatial
distribution of the positive cases was mapped and average nearest neighbour analysis used to determine the
spatial pattern of trypanosome cases detected.
Findings: Trypanosome prevalence of 41% and 29% in Suba and Teso districts respectively was observed. T. vivax
infections were most prevalent in both areas. Higher proportions of T. brucei infections (12%) were observed in
Suba, a known sleeping sickness foci compared with 2% in Teso. Average nearest neighbour analysis showed the
pattern of trypanosome infections as random. An overlay with tsetse maps showed cases lying outside the tsetse
infested areas, mostly being cases of T. vivax which is known to be transmitted both biologically by tsetse and
mechanically by biting flies.
Conclusion: These findings suggest a need to design control strategies that target not just the biological vector
tsetse, but also the parasite in cattle in order to clear the possibly m | en |
