drastic cutaneous multi-focal orf infection in goats, causing severe dysfunctioning.a flock of 76 goats was struck by orf infection at the al-ahsa oasis in eastern saudi arabia. the morbidity rate was 89%, while the case fatality rate was 3%. the clinical signs were most severe in three adult goats, which survived, and in two kids, which died of the infection. the lesions were multi-focal and so serious that they prevented the infected goats from seeing, eating, lactating or walking. the virus was isolated in vero cell culture and a scab suspension was used to experimentally in ...200920462159
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
hyalomma (hyalommina) arabica: nymphal and larval identity and spiny mouse hosts in saudi arabia (acarina: ixodoidea: ixodidae).nymphal and larval hyalomma (hyalommina) arabica pegram, hoogstraal, and wassef, 1982, described herein, closely resemble those of hyalomma (hyalommina) rhipicephaloides neumann, differing chiefly in body size (both stages), nymphal basis capituli and scutal proportional dimensions, and distinctness of larval coxal spurs. females of these species are also structurally similar but males differ in major critical characters. nymphs and larvae of both species parasitize the spiny mouse (acomys spp.) ...19854057007
isolation of a virus serologically related to the bluetongue group from an outbreak of haemorrhagic disease among exotic deer in saudi february 1991 a severe haemorrhagic disease affected exotic deer aged over six months in the al-hofuf area of the eastern region of saudi arabia. the morbidity rate was 40 per cent and the case fatality rate was 60 per cent. the clinical signs were high temperature (up to 41.5 degrees c), nasal discharge, slight salivation and lacrimation, congestion of the conjunctivae, torticollis, tremors when trying to stand, recumbency and coma leading to death. post mortem examination revealed a severe ...19921333668
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
