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
hydatid disease in the turkana district of kenya, iv. the prevalence of echinococcus granulosus infections in dogs, and observations on the role of the dog in the lifestyle of the turkana.the prevalence of echinococcus granulosus in dogs in the turkana district of kenya was 39.4% of 695 examined. of these, 98 (35.8%) had heavy echinococcus worm burdens (10(3)-5 x 10(4) ), while 54 (19.7%) and 122 (44.5%) had medium (201-1000) and light (1-200) burdens. the possible sources of these infections are discussed. the prevalence rate differed in various parts of the district, ranging from 63.5% in the northwest, where the highest incidence of human hydatidosis also occurs, to nil along ...19853985706
observations on rinderpest in kenya, 1986-1989.rinderpest was confirmed in kenya in 1986, 1987, 1988 and 1989. three epidemiologically distinct events appear to have occurred: repeated outbreaks in west pokot district related to cross-border movement of stock, an outbreak in marsabit district in 1987 (thought to have been caused by illegal movement of cattle, possibly in vehicles, from countries further north) and a series of related outbreaks in and near nairobi between 1988 and 1989 due to the unauthorized movement from abattoirs and holdi ...19921472724
isolation of campylobacter spp. and yersinia enterocolitica from domestic animals and human patients in kenya.rectal swabs or faecal samples from 992 domestic animals and 97 human patients in the nairobi region were cultured for thermophilic campylobacter species and yersinia enterocolitica. the highest isolation rate of campylobacters was obtained from diarrhoeic pigs (55.1%), followed by healthy chicken (51.5%), diarrhoeic dogs (47.2%), healthy pigs (44.0%), healthy ducks (29.4%), healthy goats (6.3%), healthy cattle (5.8%), diarrhoeic humans (3.1%), and healthy sheep (2.0%). only one strain of y. ent ...19883345259
a survey of nairobi sheep disease antibody in sheep and goats, wild ruminants and rodents within kenya.the distribution of antibody to nairobi sheep disease in sheep and goats in kenya was found to coincide closely with that of the tick, rhipicephalus appendiculatus. the proportions of a population in an enzootic area with antibody was similar in the different age groups. no antibody to the virus was found in rodent sera and while some low titres were found in some wild ruminant sera, these were considered to be most likely cross reactions with antibody to related viruses.1978701789
nairobi sheep disease in kenya. the isolation of virus from sheep and goats, ticks and possible maintenance hosts.nairobi sheep disease was seen principally upon movement of susceptible animals into the enzootic areas. this occurred most frequently for marketing purposes near the main centres of population. other outbreaks followed local breakdowns in tick control measures. the disease did not occur in epizootic form during the period under consideration. nairobi sheep disease was isolated from pools of rhipicephalus appendiculatus but not from many pools of other tick species. no virus was isolated from th ...1978701790
arbovirus isolations from ixodid ticks infesting livestock, kano plain, kenya.in a study conducted on the kano plain, kenya, virus isolation attempts were made on ixodid ticks collected, over a 14-month period, from livestock held in family enclosures (bomas) before releasing the animals for daily foraging. 8735 amblyomma variegatum (fabricius) were tested, 98.6% of which were taken from cattle, yielding 36 strains of dugbe (dug), four strains of nairobi sheep disease (nsd), three strains of bhanja (bha), one strain of thogoto (tho) and five strains of virus which could n ...19807210125
