a comparison of african buffalo, n'dama and boran cattle as reservoirs of trypanosoma congolense for different glossina species.teneral glossina morsitans centralis machado were fed on the flanks of the african buffalo (syncerus caffer sparrman), n'dama (bos taurus l.) or boran (bos indicus l.) cattle infected with trypanosoma congolense broden. the infected tsetse were maintained on rabbits and on day 30 after the infected feed, the surviving tsetse were dissected to determine the infection rates. the mean infection rates (% +/- se) in the midgut of tsetse fed on buffalo, n'damas and borans were 23.5 +/- 3.3, 31.6 +/- 2 ...19921421502
susceptibility of african buffalo and boran cattle to trypanosoma congolense transmitted by glossina morsitans centralis.four african buffalo (syncerus caffer) and four boran cattle (bos indicus) were each exposed to the bites of 10 tsetse flies infected with trypanosoma congolense. although both groups of animals became infected, the buffalo showed no clinical signs of trypanosomiasis while the cattle suffered from the disease characterized by pronounced skin reactions, high parasitaemia and severe anaemia. the prepatent periods in the buffalo varied from 18 to 27 days in comparison with 11 to 14 days in the catt ...19902343539
susceptibility of african buffalo and boran cattle to intravenous inoculation with trypanosoma congolense bloodstream forms.this study compares the susceptibility of african buffalo (syncerus caffer) and boran cattle (bos indicus) to intravenous infection with t. congolense blood stream forms. the trypanosomes multiplied in the buffaloes and the boran and reached levels of detectable parasitaemia 4 days after infection in the boran and 10 days after infection in the buffalo. the cattle developed severe anaemia and had to be treated 60 days after infection to save them from dying whereas the buffaloes did not develop ...19902382098
study on the sequential tsetse-transmitted trypanosoma congolense, t. brucei brucei and t. vivax infections to african buffalo, eland, waterbuck, n'dama and boran cattle.susceptibility of african buffalo, eland, waterbuck, n'dama and boran cattle to sequential glossina morsitans centralis-transmitted infections of trypanosoma congolense, t. brucei brucei and t. vivax was compared, and their possible role as reservoirs of these parasites for g. moristans centralis, g. pallidipes, g. austeni, g. brevipalpis and g. longipennis determined. the buffalo, eland, waterbuck and n'dama controlled t. congolense parasitaemias and were able to prevent anaemia. by contrast, o ...19999950344
characterisation of the wildlife reservoir community for human and animal trypanosomiasis in the luangwa valley, zambia.animal and human trypanosomiasis are constraints to both animal and human health in sub-saharan africa, but there is little recent evidence as to how these parasites circulate in wild hosts in natural ecosystems. the luangwa valley in zambia supports high densities of tsetse flies (glossina species) and is recognised as an historical sleeping sickness focus. the objective of this study was to characterise the nature of the reservoir community for trypanosomiasis in the absence of influence from ...201121713019
virulence of trypanosoma congolense strains isolated from cattle and african buffaloes (syncerus caffer) in kwazulu-natal, south africa.trypanosoma congolense and trypanosoma vivax are major species that infect cattle in north-eastern kwazulu-natal (kzn), south africa. of the two genetically distinct types of t. congolense, savannah and kilifi sub-groups, isolated from cattle and tsetse flies in kzn, the former is more prevalent and thought to be responsible for african animal trypanosomosis outbreaks in cattle. furthermore, variation in pathogenicity within the savannah sub-group is ascribed to strain differences and seems to b ...201425685920

[serological evidence of the existence of a wild reservoir of trypanosoma brucei gambiense in the pendjari biosphere reservation in the republic of benin].in the national park of pendjari, situated in the north-west of benin, 91 wild animals, belonging to seven species, were darted. thick and thin blood smears were examined for trypanosomes and plasma for trypanolytic antibodies against 6 antigenic variants of trypanosoma brucei gambiense. parasites were found in 13.92% and trypanolytic antibodies in 20.88% of the samples. a total of 28.57% of animals were positive by at least one of the two test systems used. morphologically trypanosoma congolens ...19921417158
