In this study, the sera collected from a variety of mammalian species (ass-mules, cat, cattle, dog, horse, human and sheep) in 10 representative provinces Turkey, were surveyed for presence neutralizing antibodies to West Nile virus (WNV). Overall, 1 40 (2.5%) ass-mules, 4 100 (4%) 43 114 (37.7%) dogs, 35 259 (13.5%) horses, 18 88 (20.4%) humans (1%) sheep, tested positive WNV-neutralizing antibodies. The results indicate that wide range mammals are exposed Nile-related could contribute...

Forty pestivirus isolates sampled from cattle in Turkey between 2002 and 2007 were characterized according to 5′ untranslated region (5′UTR) sequences autoprotease (Npro) gene sequences. The sampling of Bovine virus diarrhoea viruses (BVDVs) 15 farms five different regions indicated that BVDV 1-l (18/40, 45%) was the predominant genotype Turkey; samples also contained genotypes 1-f (10/40, 25%), 1-b (7/40, 17.5%), 1-d (3/40, 7.5%), 1-a (2/40, 5%), respectively.

The purpose of this study was to detect antibodies against Bovine Viral Diarrhea Virus (BVDV) in blood and milk serum samples. With aim, a total 192 samples were collected from unvaccinated Holstein cows Kars district Turkey. Blood tested determine the presence BVDV by commercial indirect enzyme-linked immunosorbent assay (ELISA). In study, while 172 (89.58%) found be positive for antibodies, 161 (83.85%) positive. addition, 150 (78.12%) both same cattle antibodies. Only 22 (11.45%) detected...

In this study, the physical examination of 22 cattle revealed clinical signs malignant catarrhal fever (MCF). Peripheral blood leukocyte (PBL) samples cattle, and nasal (n = 7) conjunctival 9) swab from 16 sheep two different farms, were taken for laboratory examination. The diagnosis MCF in cows was confirmed by detection ovine herpesvirus type 2 (OvHV-2) DNA polymerase chain reaction (PCR). OvHV-2 detected nested-PCR PBL one cow with (1/7)-conjunctival(1/9) housed same barn. According to...
