Herd-level prevalence of Mycoplasma bovis in Swedish dairy herds determined by antibody ELISA and PCR on bulk tank milk and herd characteristics associated with seropositivity

In this cross-sectional study, we investigated the prevalence of Mycoplasma bovis in bulk tank milk (BTM) and herd characteristics associated with a positive antibody test result in Swedish dairy herds. BTM samples from all Swedish dairy herds (n=3,144) were collected and analyzed with ID Screen antibody ELISA and PCR. Information on herd characteristics was collected from the national Dairy Herd Improvement (DHI) database. To identify herd characteristics associated with the presence of antibodies in BTM, logistic regression was used in four different models.
