| 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. ... | 1987 | 3331134 |
| preliminary survey of ticks (acari: ixodidae) on cattle in northern sudan. | in a cross sectional survey conducted during the period june 2001 to july 2002, the geographical distribution of ticks on cattle in the sudan was determined. seventeen locations were surveyed from northern, central, eastern, western, blue nile and white nile provinces. total body collections of ticks were made from 20 cattle at each location. four tick genera and 11 species were identified. the tick species collected included amblyomma lepidum, amblyomma variegatum, boophilus decoloratus, hyalom ... | 2004 | 15732459 |
| onchocerca armillata railliet and henry, 1909 and onchocerca gutturosa (neumann, 1910) in camels (camelus dromedarius l.) in the sudan. | a study undertaken to determine the onchocerca species infecting camels that live in the same localities as cattle in the dinder region, blue nile province, sudan revealed concurrent infections with the bovine parasites onchocerca armillata in the thoracic aorta, brachiocephalic trunks and brachial arteries and onchocerca gutturosa in the ventral side of the lamellar parts of the ligamentum nuchae. the microfilariae of both species had the same predilection sites in the skin of the ears, head an ... | 1988 | 3222922 |
| 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 ... | 2011 | 22040487 |
| natural exposure of dromedary camels in sudan to infectious bovine rhinotracheitis virus (bovine herpes virus-1). | the occurrence of bovine herpes virus-1 (bhv-1) in camels was studied. a total of 186 pneumonic camel lungs were collected from slaughter houses at four different areas in sudan during 2000-2006. using sandwich elisa 1.6% of 186 tested lungs were found positive for bhv-1 antigen, all were from tambool at central sudan. direct fluorescent antibody test (fat) was used to confirm the bhv-1 elisa positives, all elisa positives were also positive. pcr was used to detect bhv-1 genome with three positi ... | 2009 | 19433051 |
| observations on the trypanosomosis problem outside the tsetse belts of sudan. | entomological and trypanosomosis surveys were conducted in the blue nile area between admazien and khartoum. the surveys showed the area to be tsetse free. the only species of trypanosome found to infect cattle in this study was trypanosoma vivax, which infected some of the local cattle that had no history of entering tsetse belts. the prevalence of disease varied with the season. high disease prevalence coincided with the periods when tabanid and stomoxy flies were abundant. the study showed th ... | 2005 | 16642767 |
| 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 ... | 1984 | 6740919 |
| an outbreak of bovine trypanosomiasis in the blue nile state, sudan. | abstract: background: in this paper, we report an outbreak of bovine trypanosomiasis in kurmuk district, blue nile state, sudan that involved an infection with four trypanosoma species in cattle. the outbreak occurred in june 2010 when indigenous cattle, mainly kenana and fulani breed types, crossed the national sudanese border to ethiopia and returned. a veterinarian was notified of massive deaths in the cattle populations that recently came from ethiopia. all animals involved in the outbreak w ... | 2011 | 21569459 |
