Abstract

In this study, the physical examination of 22 cattle revealed clinical signs of malignant catarrhal fever (MCF). Peripheral blood leukocyte (PBL) samples of the 22 cattle, and nasal (n = 7) and conjunctival (n = 9) swab samples from 16 sheep from two different farms, were taken for laboratory examination. The clinical diagnosis of MCF in cows was confirmed by the detection of ovine herpesvirus type 2 (OvHV-2) DNA by polymerase chain reaction (PCR). OvHV-2 DNA was detected by nested-PCR in PBL of one cow with clinical signs and nasal (1/7)-conjunctival(1/9) swab samples of two sheep housed in the same barn. According to the sequence analysis, three slightly divergent viruses were detected. The results indicate the need for additional research in different regions of Turkey to gain a better understanding of the incidence of MCF and its implications for the livestock industry.
