| dermatophilosis in camels (camelus dromedarius linnaeus, 1758) in kenya. | natural dermatophilosis (caused by dermatophilus congolensis van saceghem, 1915) has only recently been described in camels (camelus dromedarius). further work has shown that the disease is actually widespread. at the ol maisor farm where it was first diagnosed (in the laikipia district of northern kenya), detailed investigations have revealed that thirty camels (ten calves and twenty adult animals) were infected. the signs varied from mild to more than 50% skin involvement. patches of wool on t ... | 1992 | 1305855 |
| molecular evidence of the camel strain (g6 genotype) of echinococcus granulosus in humans from turkana, kenya. | cystic echinococcosis (ce) is a zoonotic helminthic disease, which is widely distributed throughout the world. although g1 is the echinococcus granulosus genotype most commonly involved in ce in humans, the prevalence of infection with other genotypes, such as g6, may be higher than previously thought. we performed molecular analysis to identify which e. granulosus genotypes are the causative agents of ce in humans in kenya's turkana district. during a hydatid control programme in 1993-1994, 71 ... | 2010 | 19786289 |
| the socio-economic impact of important camel diseases as perceived by a pastoralist community in kenya. | this paper presents the results of a study conducted in a pastoral community in kenya using participatory appraisal approaches. the objective of the study was to assess the socio-economic impact of camel trypanosomosis (surra) according to the perceptions of the pastoralists. four livestock grazing units were conveniently selected and in each of them, three groups of key informants comprising five to eight persons were selected for the participatory exercises. five camel diseases were listed in ... | 2006 | 17283727 |
| community perceptions of important camel diseases in lapur division of turkana district, kenya. | this paper presents the results of a study conducted in lapur division of turkana district, kenya, to estimate the incidence and mortality of camel trypanosomosis using participatory methods. four livestock camps ('adakars') were conveniently selected for the study. four informant groups comprising 6 8 key persons were used for the participatory exercises. the camel diseases identified by the pastoralists in their order of importance according to annual incidence were: trypanosomosis (11.4%); ma ... | 2005 | 15747856 |
| detection of trypanosoma evansi in camels using pcr and catt/t. evansi tests in kenya. | camel trypanosomosis (surra) causes high morbidity and is an impediment to the camel husbandry in kenya. the lack of a sensitive diagnostic test has hindered the collection of accurate epidemiological data and institution of control programmes. a cross-sectional study was conducted in three districts of kenya to estimate the prevalence of trypanosoma evansi (t. evansi) and to compare four diagnostic tests: polymerase chain reaction (pcr), card agglutination test (catt/t. evansi), microhaematocri ... | 2004 | 15381299 |
| genetic diversity and relationships of indigenous kenyan camel (camelus dromedarius) populations: implications for their classification. | the genetic diversity and relationships amongst the dromedary (camelus dromedarius) populations are poorly documented. four recognized kenyan dromedary breeds (somali, turkana, rendille, gabbra) and dromedary from pakistan and the arabian peninsula (saudi arabia, united arab emirates) were studied using 14 microsatellite loci. phylogenetic analysis showed that kenyan dromedaries are distinct from arabian and pakistani populations. expected heterozygosity and allelic diversity values indicate tha ... | 2003 | 12580783 |
| an investigation of camelpox outbreaks in two principal camel (camelus dromedarius) rearing areas of kenya. | in 1992, during an investigation into camelpox in two principal camel-rearing areas of kenya, the disease was found in 1,100 camels at a prevalence of 6% in turkana and 27% in samburu. in turkana, outbreaks were detected in two herds of young animals, while in samburu, outbreaks were found in two herds of adult animals, as well as in two herds of young camels. in all cases, there was 100% morbidity in the affected herds. when young camels were involved, the main lesions were confined to the mout ... | 1997 | 9567310 |
| the epidemiology and control of camel dermatophilosis. | camel dermatophilosis was only recently described. it appears however that it is more widespread than originally thought. in kenya it has generally been found in the main semi-arid camel rearing areas of samburu and laikipia districts although it has not yet been found in the arid areas of turkana district. in an investigation of ticks on 200 camels, no amblyomma variegatum ticks were found although many other ticks were present. a. variegatum is suspected to transmit dermatophilosis in many dom ... | 1993 | 8134647 |
| molecular examination of the sympatry and distribution of sheep and camel strains of echinococcus granulosus in kenya. | previous studies have shown that camel and sheep strains of the cystic hydatid parasite echinococcus granulosus occur in kenya. we examined 208 larval isolates and 40 worm samples of e. granulosus from various hosts in kenya using restriction fragment length polymorphism analysis of a segment of ribosomal dna amplified by the polymerase chain reaction. this was in an effort to determine whether additional strains of e. granulosus occur in kenya, to examine the level of genetic heterogeneity with ... | 1993 | 8097619 |
| outbreaks of contagious ecthyma in camels (camelus dromedarius) in the turkana district of kenya. | mortality among camel calves (camelus dromedarius) is one of the most serious problems faced by camel herdsmen and, although there are several reasons for this mortality, diseases play a major role. in an investigation of outbreaks of contagious ecthyma in camels in the turkana district of kenya, four outbreaks were detected involving only camel calves. the principal lesions were distinct or largely coalesced pustules on the mouth, nose and muzzle. direct electron microscopy of infected scabs wa ... | 1994 | 7949365 |
| rift valley fever in kenya: the presence of antibody to the virus in camels (camelus dromedarius). | five hundred and seventy-one camel sera collected after an epizootic of rift valley fever were examined for antibody to the virus. clinical disease had not been observed in cattle and sheep in the ecosystems shared with the camels. positive sera with high titres of serum neutralizing antibody were found in 22% of camels at one of the seven sampling sites. | 1985 | 3989285 |
