[rift valley fever, a veterinary and medical problem (author's transl)].rift valley fever probably occurred in east and south africa for many years, where it occasionally caused sever epizootics among sheep and to a less extent in cattle and goats. particularly newborn animals fall victims to the disease, whereas the majority of pregnant ewes and cows abort. in recent years, the disease spread to the sudan and reached the nile delta in 1977, where it not only caused an epizootic but also an epidemic among the population, resulting in approximately 18,000 cases and n ...1979494210
results of serological examination for leptospirosis of domestic and wild animals in the upper nile province (sudan).195 domestic and 766 wild animals were serologically examined for leptospirosis. cattle was found to be positive at titres 1 greater than or equal to 400 in 63.5%, namely 50.6% for tarassovi, 17.1% for sejroe-hebdomadis, 9.4% for bataviae, 1.2-3.5% for icterohaemorrhagiae, cynopteri, autumnalis, australis, pomona and grippotyphosa. sera from 35 animals reacted with the serovars from two or more serogroups. of 7 sheep 1 was positive for pomona and 18 goats proved to be negative. 10.2% of wild mam ...19892809189

ticks (acari:ixodidae) of the blue and white nile ecosystems in the sudan with particular reference to the rhipicephalus sanguineus group.twenty-four adult ixodid tick species, infesting livestock and some wildlife hosts along the blue and white nile in the sudan, were identified. three species, boophilus geigyi, rhipicephalus camicasi and r. bergeoni, were recorded for the first time from the sudan. tick numbers on indigenous breeds of cattle (bos indicus) were relatively low, ranging between 17.1 and 40.5 per animal. young cattle grazing with the herd carried significantly fewer ticks than older animals. with the exception of b. ...19873331134

preliminary survey of domestic animals of the sudan for precipitating antibodies to rift valley fever a preliminary seroepidemiological survey a total of 780 serum samples derived from various domestic animals of the sudan were examined for rift valley fever (rvf) virus precipitating antibodies. the incidence was approximately 34.3% in sheep, 33.2% in cattle, 22% in goats, 7.9% in camels and 4% in donkeys. the findings indicated that rvf is mainly prevalent in the rich savanna areas of the south as well as the irrigated areas close to the nile in the north. circumstantial evidence suggests th ...19846512261
age specific prevalence and intensity of schistosoma bovis infection in sudanese desert sheep in the white nile province.a survey of ovine schistosomiasis was carried out in a schistosoma bovis enzootic area in the central sudan. three hundred desert sheep, representing different age groups, were screened for infection, using pitchford's faecal egg counting technique. no infection was detected in animals under one year old, but from the age of 18 months onward, the prevalence increased progressively from around 20 per cent to 60 per cent in six-year-old sheep, and this was accompanied by an increase in infection i ...19836622838
detection of antibodies to leishmania donovani in animals in a kala-azar endemic region in eastern sudan: a preliminary report.the prevalence of antibodies against leishmania donovani in selected domestic and wild animal species in 2 villages in sudan with active l. donovani transmission in humans was investigated. screening of domestic animals (donkeys, cows, sheep, goats, camels and dogs) with the direct agglutination test (dat) detected reaction rates above the cut-off titres in donkeys (68.7%), cows (21.4%) and goats (8.5%), and which were also found in wild rats (5.5%). sera of sheep, camels and dogs had a weak agg ...200010748894
managing the wetlands. people and rivers: the current population growth rate in africa, the population will reach 1 billion by 2010. water is needed to sustain these people, yet rainfall in africa is erratic. africans are already confronting a shortage of freshwater. agriculture supports 66% of the population of sub-saharan africa. sound agricultural development is needed to curb rural-urban migration, but a constant supply of freshwater is essential. major rivers (the limpopo in southern africa and the save/sabi in zimbabwe and ...199312287015
some observations on ticks (acari: ixodidae) infesting sheep in river nile province of northern sudan.five species of ixodid ticks were found in a cross-sectional survey in which 200 sheep were examined for ticks in river nile province, sudan. hyalomma anatolicum anatolicum was the predominant species (73.6%), whereas ticks belonging to the rhipicephalus sanguineus group (14.7%), rhipicephalus evertsi evertsi (9.1%), rhipicephalus simus (2%) and hyalomma dromedarii (0.5%) were also found. the mean tick load was 11.2 per animal. in a subsequent longitudinal survey ticks were collected on a monthl ...200516300192
current situation of peste des petits ruminants (ppr) in the sudan.the current situation of ppr in sudan was investigated. a total of 61 tissue samples were collected from various ppr suspected outbreaks in sheep in sudan during 2008. collected tissue samples were tested for ppr antigen using icelisa, ppr antigen was detected in 26 out of 61 samples (42.6%). highest antigen detection rate was in specimens collected from western sudan. a total of 1198 serum samples were collected from sheep (n = 500), camels (n = 392), and goats (n = 306) from different areas in ...201019548103

A molecular survey on cystic echinococcosis in Sinnar area, Blue Nile state (Sudan).Cystic echinococcosis (CE) is a zoonosis caused by the cestodes of the Echinococcus species. Its life cycle involves dogs and other canids as definitive hosts for the intestinal tapeworm, as well as domestic and wild ungulates as intermediate hosts for the tissue-invading metacestode (larval) stage. The disease has a special impact on disadvantaged pastoralist communities and is listed now among the three top priority neglected tropical disease (NTD). Therefore, CE is a neglected disease even in ...201122040487
isolation and transmission of cowdria ruminantium (causal agent of heartwater disease) in blue nile province, sudan.heartwater was diagnosed in sheep at the umm banein livestock research station, blue nile province, sudan. cowdria ruminantium was isolated from sheep by subinoculation of blood into a goat. adult amblyomma lepidum ticks fed as nymphs on this goat transmitted heartwater to a friesian (bos taurus) calf. brain stabilates from this calf, either snap-frozen into liquid nitrogen or frozen slowly in a deepfreezer at -70 degrees c, with dmso as cryoprotectant, were infective to cattle when inoculated s ...19846740919
