“…In the Middle East, B. melitensis has been isolated from an Arabian oryx (Oryx leucoryx) in Saudi Arabia (69). However, most B. melitensis infection cases occur in nomadic onehumped camels (Camelus dromedarius) that have been in contact with sheep and goats (1).…”

The epidemiological link between brucellosis in wildlife and brucellosis in livestock and people is widely recognised. When studying brucellosis in wildlife, three questions arise: (i) Is this the result of a spillover from livestock or a sustainable infection in one or more host species of wildlife? (ii) Does wildlife brucellosis represent a reservoir of Brucella strains for livestock? (iii) Is it of zoonotic concern? Despite their different host preferences, B. abortus and B. suis have been isolated from a variety of wildlife species, whereas B. melitensis is rarely reported in wildlife. The pathogenesis of Brucella spp. in wildlife reservoirs is not yet fully defi ned. The prevalence of brucellosis in some wildlife species is very low and thus the behaviour of individual animals, and interactions between wildlife and livestock, may be the most important drivers for transmission. Since signs of the disease are non-pathognomonic, defi nitive diagnosis depends on laboratory testing, including indirect tests that can be applied to blood or milk, as well as direct tests (classical bacteriology and methods based on the polymerase chain reaction [PCR]). However, serological tests cannot determine which Brucella species has induced anti-Brucella antibodies in the host. Only the isolation of Brucella spp. (or specifi c DNA detection by PCR) allows a defi nitive diagnosis, using classical or molecular techniques to identify and type specifi c strains. There is as yet no brucellosis vaccine that demonstrates satisfactory safety and effi cacy in wildlife. Therefore, controlling brucellosis in wildlife should be based on good management practices. At present, transmission of Brucella spp. from wildlife to humans seems to be linked to the butchering of meat and dressing of infected wild or feral pig carcasses in the developed world, and infected African buffalo in the developing world. In the Arctic, the traditional consumption of raw bone marrow and the internal organs of freshly killed caribou or reindeer is an important risk factor.

“…Health monitoring is consequently crucial to secure the species’ conservation, especially when there is evidence of the Arabian oryx’s susceptibility to specific etiological agents known to affect livestock [ 6 ], presenting a risk of infection to the relocated animals either with previously present agents or by introducing novel pathogens into naïve regions [ 7 ]. Previous epidemiological studies that targeted the causes of different diseases by screening the oryx were limited to bacteria [ 8 , 9 ], including Mycobacterium [ 10 , 11 ] and Mycoplasma [ 12 ]; mites [ 5 , 13 ]; parasites (both helminths [ 14 ] and protozoa [ 15 , 16 , 17 ]); prions [ 18 , 19 ]; and viruses [ 2 , 20 , 21 , 22 ] as the causative agents investigated. No data are available on other zoonotic or tick-borne pathogens that may affect the Arabian oryx’s health.…”

The Arabian Peninsula’s endemic ungulate, Oryx leucoryx, was on the verge of extinction at the end of the 1970s. Despite the different reintroduction programs, the International Union for Conservation of Nature is still classifying it as Vulnerable. Among other factors, their vulnerability lies in their susceptibility to specific etiological agents that affect livestock, necessitating health monitoring and strict preventive/biosecurity measures. Within this frame, the current work investigated the determination of the etiological agent potentially involved with cutaneous lesions observed in eight males of Arabian oryx within one of the several national governance conservation programs. Microscopic examination from one animal specimen suggested theileriosis association, which was confirmed by molecular tools using 18S gene sequencing and the report of a novel Theileria sp. not clustering with previously reported antelope sequences. This finding prompts further explorations into the disease dynamics within the Arabian oryx population, especially with the scarcity of data in Qatar about tick-borne pathogens and their transmission.
