A total of 860 serum samples collected at 86 cattle farms in different parts of Hungary were screened for the presence of antibodies to Mycoplasma bovis using an ELISA test with a recombinant M. bovis membrane protein as antigen. Antibodies to M. bovis were detected in sera collected on all farms, and no farms negative for M. bovis were found. In 88.38% of the herds more than 50% of the sampled animals were infected by M. bovis. A total of 82.91% of the animals had antibodies to M. bovis. The proportion of seropositive animals was higher in the older age groups, and a significant difference was seen in the level of seropositivity between young and older age groups. The results show that M. bovis infection is widespread on Hungarian dairy farms, and its prevalence has increased in the recent decade. The high infection rate of Hungarian cattle herds with M. bovis shows that special attention should be paid to evaluating the aetiological role of M. bovis in bovine respiratory disease complex (BRDC) cases because M. bovis has an immunosuppressive effect and can predispose cattle to other respiratory infections, too.
