Molecular epidemiological survey and genetic characterization of ovinegammaherpesvirus-2 in Mongolian livestock

چکیده
Sheep-associated malignant catarrhal fever (SA-MCF), caused by ovine gammaherpesvirus-2 (OvHV-2), is a fatal disease in all ruminants. The epidemiological survey and molecular characterization of OvHV-2 in Mongolian livestock were performed. Of 928 blood samples, 14 were positive for OvHV-2 in sheep and native cattle from Tsenkher County and in sheep from Lun County. Phylogenetic analyses revealed that the tegument gene of OvHV-2 sequences from Mongolian animals is identical to that in animals from Egypt, India, and Turkey, and is 98.0% similar to that in animals from Germany and Brazil. To our knowledge, this is the first confirmed report of OvHV-2 in Mongolian livestock, and could provide useful information for controlling SA-MCF.

The first genetic identification of Theileria ovis subtype KP019206 in sheep in Iran
Ticks and tick-borne diseases, including theileriosis, constitute a major constraint to livestock production. Two species, known as Theileria lestoquardi and Theileria ovis, are suspected to contribute to ovine theileriosis in Iran. However, the epidemiological aspects of ovine theileriosis are poorly understood in this country. In a survey, designed to identify Theileria species in sheep, 52 (...
