“…Similarly, consistent with our findings, the prevalence of orf in other parts of the world is high [22]. Orf infection reported was 19.51% among lamb in England [24], 34.89% in China [11], staggering 98% Nilgiri Hills in Tamil Nadu, India [33] and 54% in Saudi Arabia [34]. Gökce et al [28] had also reported a high sero-conversion rate of 52.8% among lambs within some selected districts in Turkey.…”

An association of Orf virus infection among sheep and goats with herd health programme in Terengganu state, eastern region of the peninsular Malaysia

Background Orf virus causes a scabby skin lesions which decreases productivity in small ruminants. The unknown status of this disease in the eastern region of Peninsular Malaysia warrants a study to determine sero-prevalence of orf with regards to farmers’ compliance level towards the Herd Health Program (HHP) programme. Results Out of 504 animals, 115 were positive for Orf-virus antibodies. An overall prevalence rate of 22.8% indicated a high prevalence of orf disease in this region. It was observed that 25.1% (92/367) of goats were positive and 16.8% (23/137) of sheep sero-converted for Orf virus antibody. Several factors were measured for their possible association with prevalence of Orf virus infection. The prevalence was higher in LY farm, JC breed, kid and female animals, and in the presence of disease lesion. Chi-square analysis showed a significant association of three risk factors which are species, age and sex of the animals ( P < 0.05). Notwithstanding, all other variables showed no significant difference ( P > 0.05). Farms surveyed usually practised intensive management system, keeping animals in the shade at all time, due to limited availability of suitable land as a free-range grazing area. An interview with small holder farmers revealed a lack of awareness of the main goals of herd health programme. An overall compliance level of 42.7% was observed for all HHP parameters. Among the 14 main components of HHP modules, animal identification had recorded highest compliance level (84.62%) while milking management recorded the least compliance (− 82.69%). That explained why there was a high sporadic prevalence of Orf infection in this region. Conclusion Good herd health supervision is a rehearsal target to prevent an outbreak and the spread of diseases thus reduces economic losses among farmers. Therefore, a good herd health programme should be in place, in order to prevent and control disease transmission as well as to improve herd immunity.

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 infect susceptible goats. These newly infected animals suffered only mild disease but the orf virus was re-isolated and the goats seroconverted. To the best knowledge of the authors, these were the most drastic orf lesions seen during the last 17 years in goats in Saudi Arabia.

“…Although, PPR has previously been reported from the Kingdom (Abu Elzein et al, 1990) but none of the samples screened during the present study show evidence of this disease, which means that the disease is absent from the two protected areas investigated. Likewise the infectious pustular dermatitis (orf) has been reported to be widely distributed in the Kingdom (Housawi et al 1992;Gameel et al 1995;Abu Elzein and Housawi, 1997), during the present investigation, however, none of the samples screened from UBM protected areas showed any evidence for this disease. Animals screened from the Ibex Reserve, however showed antibodies against orf and infected domestic animals are certainly a potential source of infection to wildlife and humans in the area.…”

“…Diseases of domestic livestock in Saudi Arabia which can potentially be transmitted to wildlife as a result of coming in contact have been reported in the Kingdom (Abu Elzein et al, 1990;2004;Housawi et al, 1992;Hussein et al, 1988;Mohammed and Hussein, 1994). In the present investigation a serological disease survey for some common prevalent diseases in the Kingdom has been carried out to assess how prevalent these diseases in domestic livestock raised in some protected areas where some susceptible wildlife were reintroduced.…”

The aim of this study is to investigate the prevalence of some diseases in domestic livestock in two protected areas in Saudi Arabia where gazelles have been reintroduced. King Khalid Wildlife Research Centre (KKWRC) was established in 1986 to breed and undertake scientific research on Saudi wildlife for reintroduction purposes. Mountain gazelles (Gazella gazella) were reintroduced to the Ibex Reserve 150 km south of Riyadh in central Saudi Arabia, which supports viable population of wild ibex. Sand gazelles (Gazella marica), Mountain gazelles and Arabian oryx (Oryx leucoryx) were reintroduced to Uruq Bani Ma'arid (UBM) Reserve in the Al Rub al Khali desert. Domestic livestock (camels, sheep and goats) owned by local people use the Reserves and the area surrounding for grazing and there is contact between these animals and reintroduced wildlife. Two surveys have been carried out at each Reserve. Serum samples collected from 1012 camel, sheep and goats were screened for some viral, bacterial and parasitic diseases that are of particular concern in Saudi Arabia. The results show the presence of antibodies against tuberculosis, brucellosis, bluetongue virus, akabane virus, contagious pustular dermatitis and toxoplasmosis. The Suadi Wildlife Authority (SWA) coordinated with the Ministry of Agriculture and established monitoring and remedial programmes to control diseases reported in the present study. The epidemiological significance, of the study, to wildlife was discussed.
