| 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 |
| abortion rate and mortality among exotic pregnant heifers imported to the gezira in the central region of the sudan. | despite the intensive management and husbandry precautions, exotic pregnant heifers imported to the gezira, sudan, suffered excessive stress. four of five heifers aborted due to stress. death was due to pasteurellosis, babesiosis and heart water. | 1987 | 3617420 |
| domestic and wild animals naturally infected with schistosoma mansoni in the gezira irrigated scheme, sudan. | domestic and wild animals were examined for natural infection with human schistosomiasis in northern gezira, sudan. postmortem examination of animals in a number of slaughterhouses revealed no infections in either sheep or goats but schistosoma mansoni worms were found in two of the 98 cattle examined. nile rats (arvicanthus niloticus) were trapped and stray dogs were shot and examined for evidence of schistosome infection. the infection rate in nile rats was 4.9% (8/164) and in dogs 27.3% (15/5 ... | 1985 | 4032533 |
| a possible association between dietary intake of copper, zinc and phosphate and delayed puberty in heifers in sudan. | zinc and copper deficiencies have been reported in heifers of various breeds at four different locations in sudan. these were kuku (5 km north of khartoum), seleit (20 km northwest of khartoum), medani (180 km south of khartoum) and el obeid (600 km west of khartoum). phosphorus deficiency was only observed in the serum of heifers at el obeid. the heifers at all locations showed delayed puberty, stunted growth and infertility. the heifers of the local breeds at el obeid only attained puberty by ... | 2002 | 11887424 |
| cystic echinococcosis of livestock and humans in central sudan. | new information was collected on cystic echinococcosis in livestock (camels, cattle and sheep) and humans in the central region of sudan. the livestock data were collected in abattoir-based surveys in the towns of omdurman, tamboul and wad madani, between 1998 and 2001, and covered a total of 8205 animals. the highest prevalence of infection was found in the camels (44.6% of 242 infected), followed by the sheep (6.9% of 5595) and cattle (3.0% of 2368). records were made of the sizes of the 1320 ... | 2004 | 15257797 |
| natural infection rates and transmission of theileria annulata by hyalomma anatolicum anatolicum ticks in the sudan. | hyalomma anatolicum anatolicum nymphs were collected from two localities in the sudan: eddamer in northern sudan and wad-medani in central sudan. they were allowed to moult to adult ticks, which were assessed for theileria infection in their salivary glands using feulgen stain. at eddamer, 49.6% of 123 ticks examined were infected with theileria and the mean intensity of infection was 1.3 (i.e. the number of infected acini/number of infected ticks). at wad-medani, 8.6% of 162 ticks were infected ... | 2005 | 16562733 |
| insecticide susceptibility and vector status of natural populations of anopheles arabiensis from sudan. | species composition, blood meal source, sporozoite infection rate, insecticide resistance and the kdr mutations were investigated in the anopheles gambiae complex from 13 sentinel sites in central sudan. species identification revealed that 89.5% of 960 specimens were a. arabiensis. of 310 indoor resting females, 88.1% were found to have fed on humans, while 10.6% had fed on bovines. the overall sporozoite infection rate from the five localities tested was 2.3%, ranging from 0 to 5.5%. insectici ... | 2008 | 18054056 |
