dynamics of host blood effects in glossina morsitans sspp. infected with trypanosoma congolense and t. brucei.the pattern of infection in glossina morsitans morsitans and g. m. centralis membrane-fed on eland, buffalo or goat blood mixed with trypanosoma congolense or t. brucei was studied from day 1 to day 10. tsetse were initially permissive vectors, with most flies harbouring infections of 10(4)-10(5) parasites on day 3. however, after a second blood meal on day 3, flies cleared many infections, with g. m. morsitans clearing more infections than g.m. centralis. infective feeds of goat blood consisten ...19948036228
relationships between protease activity, host blood and infection rates in glossina morsitans sspp. infected with trypanosoma congolense, t. brucei and t. simiae.midgut protease activity in glossina morsitans centralis and g.m. morsitans, at 48 h post bloodmeal averaged 1.8iu of trypsin-like activity. these two tsetse subspecies differ in their susceptibility to trypanosome infection. except for low levels in flies fed on waterbuck blood (0.7 iu), activity did not differ in flies fed a variety of host bloods (goat, pig, cow, buffalo, eland) and trypanosome species (trypanosoma congolense, t. brucei, t. simiae). protease activity was also not correlated w ...19948161844
the influence of host blood on infection rates in glossina morsitans sspp. infected with trypanosoma congolense, t. brucei and t. simiae.trypanosoma congolense, t. brucei and t. simiae isolated from wild-caught glossina pallidipes were fed to laboratory-reared g. morsitans centralis and g.m. morsitans to determine the effect of host blood at the time of the infective feed on infection rates. bloodstream forms of trypanosomes were membrane-fed to flies either neat, or mixed with blood from cows, goats, pigs, buffalo, eland, waterbuck and oryx. the use of different bloods for the infective feed resulted in differences in infection ...19938355996
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
