High mortality rate of shipping fever cases in cattle caused by bovine herpesvirus type 1 (BoHV-1)

This study reports the high prevalence and molecular characterization of BoHV-1 infection in imported cattle with respiratory system disease after international transport. A mortality rate 14.16% (51/360) was reported a group animals from Hungary to Turkey 2019. total 17 samples were evaluated (3 lung tissue 14 nasal swab samples) 15 aged 6 9 months not vaccinated against BoHV-1. Virus isolation, polymerase chain reaction (PCR) restriction endonuclease analysis (REA) procedures performed within scope this study. By virus isolation MDBK cells, cytopathologic effects detected 8 5 swabs samples). The same eight also found positive by PCR targeting gC (UL44) gene region. According sequencing result, sample (ID: 10054) dropped into cluster BoHV-1.1. REA applied confirm results phylogenetic analysis. All isolates identified subgroup BoHV-1.1 REA. These showed risk for possibility entering receiving country via event is serious problem both control as well animal health welfare.
