prevalence of eimeria in faeces of cattle in saudi arabia.the faeces of 205 domestic cattle (bos taurus) from 5 regions of saudi arabia were examined for the presence of coccidian parasites. the following species of eimeria were recovered: eimeria auburnensis, e. bovis, e. cylindrica, e. ellipsoidalis, e. subspherica, e. wyomingensis and e. zuerni. a total of 34.1% of the individual faecal samples were positive for the presence of coccidial oocysts. mixed infections of 2-4 species were found in 15.7% of the specimens. e. zuerni and e. bovis occurred mo ...19853992872
abortions, stillbirths and deformities in sheep at the al-ahsa oasis in eastern saudi arabia: isolation of a bluetongue serogroup virus from the affected lambs.a wave of abortions, stillbirths and deformities in sheep occurred at the al-ahsa oasis in the eastern region of saudi arabia in the second half of 1999. the abortions were recorded in august and september and stillbirths and deformities in neonates were observed in october. adult sheep were clinically normal. a virus was isolated in chicken embryos, adapted to vero cell culture and further identified as bluetongue (bt) virus. the virus isolated was not neutralised by the akabane virus. referenc ...200415861886
effect of complementation of cattle cooling systems with feedline soakers on lactating dairy cows in a desert environment.two experiments were conducted on a commercial dairy farm in eastern saudi arabia to investigate the effects of korral kool (kk; korral kool inc., mesa, az) cattle cooling systems complemented with feedline soakers on core body temperature (cbt) of dairy cows. in both experiments, cows had access to kk 24h/d. in the first experiment, 7 primiparous and 6 multiparous lactating holstein dairy cows were assigned to 1 of 2 pens, which were assigned randomly to treatment sequence over 4 d in a switchb ...201121257072
observations on the recent epizootic of bovine ephemeral fever in saudi arabia.observations of the epizootic of bovine ephemeral fever which occurred in saudi arabia during 1996 are presented. the investigations included the collection of epidemiological data from affected farms and the testing of sera for antibodies to the virus. the authors report a mean morbidity rate of 50% and a mean case fatality rate of 0.3%. of the infected cattle, 4% were affected by recumbency, the majority of these recovered (89%). the clinical signs observed in affected cattle were uniform thro ...199910588011
sheep-associated malignant catarrhal fever involving 3-5-week-old calves in saudi arabia.between late december 1999 and late april 2000, three locally bred friesian calves (ageing 25, 28 and 35 days) in a dairy farm, at al-ahsa locality of the eastern region of saudi arabia showed dullness and inappetence. their rectal temperatures ranged between 41 and 41.5 degrees c. one to 2 days later and onwards, the calves showed lacrimation, nasal discharge, salivation, oedema of the head, conjunctivitis, exo-ophthalmia and corneal opacity. one calf showed diarrhoea. the superficial lymph nod ...200312675894
study of akabane infection in saudi arabia by the use of sentinel ruminants.two sentinel herds of calves (eastern and central regions of saudi arabia) and one of sheep and goats (south western region) were established to study akabane virus infection. the herd at the al-ahsa oasis (eastern region) showed evidence of akabane viral activity, as reflected by the presence of maternal (colostral) antibody, which had waned to insignificant concentrations by the time the calves had reached the age of 5 months. there was no evidence of subsequent seroconversion. the other two s ...19989839208
genital bovine papillomavirus infection in saudi arabia.genital bovine papillomavirus infection was observed for the first time in the al-ahsa region of saudi arabia. the disease involved 1 female and 2 male 2-4-year-old crossbred cattle. fibropapillomas (warts) were limited to the prepuce and vulva. electron micrographs of thin sections of the lesions revealed the presence of intranuclear viruslike particles. using a broadly cross-reactive rabbit polyclonal antiserum directed against papillomavirus group-specific antigens, the infection was confirme ...19911645597
