molecular characterization of a novel bovine viral diarrhea virus isolate one of the major pathogens, bovine viral diarrhea virus caused a significant economic loss to the livestock industry worldwide. although bvdv infections have increasingly been reported in china in recent years, the molecular aspects of those bvdv strains were barely characterized. in this study, we reported the identification and characterization of a novel bvdv isolate designated as sd-15 from cattle, which is associated with an outbreak characterized by severe hemorrhagic and mucous diarrhe ...201627764206
herd-level prevalence and associated risk factors for toxoplasma gondii, neospora caninum, chlamydia abortus and bovine viral diarrhoea virus in commercial dairy and beef cattle in eastern, northern and northeastern china.although the seroprevalence of toxoplasma gondii, neospora caninum, chlamydia abortus and bovine viral diarrhea virus infection in cattle have been reported in some areas in china, most of them were conducted with small number of cattle samples and very limited districts and neglected the assessment of herd management factors associated with herd-level prevalence of these pathogen infections. thus, from september 2013 to december 2014, a large-scale seroprevalence study was conducted to determin ...201526231838
