A cross-sectional study was carried out to investigate the seroprevalence of M. bovis. A total of 606 serum samples were randomly collected from dairy cows in Ho Chi Minh City, Vietnam. Commercial ELISA kit was used for detection of antibody to M. bovis. The results indicated that overall seroprevalence was 80.2% (486/606). There were no significant differences between regions or age categories (P > 0.05). Degree of infection to M. bovis commonly distributed at positive degree 1 (68.5%) and 2 (24.1%). Seroprevalence at highest positive degree 4 were found in District 9, District 12 and Thu Duc (6.7%, 6.3% and 1.6%, respectively). This study is the first report of seroprevalence of M. bovis in Vietnam. The results suggested that M. bovis was spreading among dairy cow populations although degree of positivity was low. It should be considered as a high risk pathogen to dairy cows in Vietnam.
