Epidemiological analysis of infection by the bovine viral diarrhea virus on family farms in Brazil
The aim of the present study was to determine the seroprevalence of infection by the bovine viral diarrhea virus (BVDV) on family farms, as well as to study the risk factors associated with the infection. In total, 319 blood serum samples were collected from cattle, of reproductive age (>24 month...
