abstract

respiratory disorders are major concern for dairy cattle industry. viruses and bacteria in combinationwith stress play a key role in triggering acute respiratory infections. the most important viral agents arebovine viral diarrhoea virus (bvdv), bovine herpes virus type 1 (bhv-1), bovine respiratory syncytial virus(brsv), parainfluenza virus type 3 (piv-3) and bovine adenovirus (bav). this cross-sectional study wasconducted to evaluate the serological status of bvdv, bhv-1, brsv, piv-3 and bav in dairy herds inkerman province, iran. from june to november 2007, 181 serum samples were collected from 1–3-year-oldcattle from 15 industrial dairy farms in kerman province using cluster sampling. the samples were tested bycommercial indirect elisa kits. antibodies were detected against bvdv, bhv-1, brsv, piv-3 and bavin 77.90, 30.39, 100, 100 and 100% of serum samples, respectively. all farms were positive at least for oneof these viruses and antibodies against all the 5 viruses were detected in 4 (26.66%) herds among 15 dairyfarms. according to the present study, bvdv, brsv, piv-3 and bav are common viruses in dairy herds inkerman province.

Molecular characterization and phylogenetic analysis of bovine viral diarrhea virus in dairy herds of Fars province, Iran

Bovine viral diarrhea virus (BVDV) is one of the most important viral pathogens of cattle worldwide. The aim of present study was to determine the molecular characterization and phylogenetic analysis of BVDV infection in dairy herds of Fars province, Iran. For initial screening, a total of 400 blood samples were collected from 12 industrial dairy herds with previous history of diarrhea, abortio...
