characterization of trypanosoma congolense serodemes in stocks isolated from cattle introduced onto a ranch in kilifi, kenya.a herd of 20 cattle was introduced on a ranch in kilifi, coast province of kenya, where they were in contact with glossina austeni for 6 months. in total, 65 trypanosome isolates were made from these animals. examination of the isolates revealed that 61 were trypanosoma congolense and 4 were t. theileri. out of the 61 t. congolense isolates, 55 were successfully passaged and cloned in mice to provide trypanosome populations for further analyses. the stocks and their clones were inoculated into g ...19873295687
bloodfeeding behavior of anopheles gambiae s.l. and anopheles funestus in kilifi district, kenya.blood meal samples were tested by elisa for 534 anopheles gambiae s.l. and 76 anopheles funestus collected from 25 sites in kilifi district, kenya. human igg was detected in 94.4% of the an. gambiae s.l. and in 90.8% of the an. funestus. no samples were positive for cow and only a few were positive for goat. both species fed predominantly on humans irrespective of host availability. at these sites on the kenyan coast, the high degree of human-feeding by malaria vectors contributes to the efficie ...19938350080
rift valley fever outbreak in livestock in kenya, 2006-2007.we analyzed the extent of livestock involvement in the latest rift valley fever (rvf) outbreak in kenya that started in december 2006 and continued until june 2007. when compared with previous rvf outbreaks in the country, the 2006-07 outbreak was the most extensive in cattle, sheep, goats, and camels affecting thousands of animals in 29 of 69 administrative districts across six of the eight provinces. this contrasted with the distribution of approximately 700 human rvf cases in the country, whe ...201020682907
trypanosoma congolense: host responses following tsetse transmitted infection of kilifi isolates in goats.east african x galla goats, when infected with trypanosoma congolense isolates from the kilifi area of kenya by glossina morsitans centralis, did not develop the characteristic chancre reaction at the bite sites, whereas bites of tsetse infected with the cloned t. congolense il.1180 from serengeti, tanzania, resulted in chancres in the same goats. histological changes could not be observed in skin biopsies collected 8 or 9 days after infection with kilifi isolates. however, all goats became para ...19873582569
the chromosome profiles of trypanosoma congolense isolates from kilifi, kenya and their relationship to serodeme identity.chromosomal dna from 117 trypanosoma congolense clones from 54 stocks, isolated from cattle introduced onto a ranch in kilifi in the coastal area of kenya, was fractionated by the orthogonal field alternation gel electrophoresis technique. the technique resolved chromosomes in the size range of 100 kb-1 mb. the chromosome profile for cloned trypanosome populations was relatively stable with regard to number and size of the chromosome bands following transmission in mice, cattle, goats or tsetse ...19883173429
prevalence of besnoitiosis in domestic ruminants in kenya: a preliminary survey.a preliminary survey on the prevalence of besnoitiosis in domestic ruminants in kenya based on field and farm visits, clinical and post mortem examinations and histopathological examination of tissues and biopsies, showed that goats are the most affected, followed by cattle, while sheep were unaffected. caprine besnoitiosis occurred in a continuous belt in 5 of the 8 provinces in kenya stretching from the coast, eastern, north eastern, nairobi and the rift valley provinces. mandera, in the north ...199910855837
