ABSTRACT
Azabo R, Abila P, Odhiambo
L, Waiswa C, Ejobi F, Okedi L., Trypanosome Infection rates in tsetse (Glossina fuscipes fuscipes) in
communal grazing lands in
Mid-northern Uganda, Onl J Vet Res., 20(4):225-236, 2016. Glossina fuscipes fuscipes is the main tsetse species of economic importance in
Uganda as it plays a major role in transmission of trypanosomosis.
Epidemiology in livestock is determined by prevalence and distribution of
arthropod vectors in affected areas and proportion of infected tsetse flies. We
found tsetse apparent densities varied between 0.21-2.13 flies/trap/day across
3 study areas with Glossina fuscipes fuscipes being the only species. 376 non teneral flies were trapped, dissected with proboscis,
salivary gland and mid-gut for microscopical
determination of trypanosome infection. 21 (5.6%) flies were infected with
trypanosomes, significantly (x2 , 8.05, d.f.= 1,P=0.002), higher in females (81%) than males (19%).
Higher infection rates occurred during wet (3.7%), than dry season (1.9%). Infections
were due to T. vivax (3.2%), T. congolense
(1.3%), and 1.1% for
immature (gut only). T. brucei was not isolated. Blood meal analysis by PCR
implicated cattle and human hosts.
