The present study investigated serological and molecular prevalence of Mycoplasma gallisepticum (MG) and Mycoplasma synoviae (MS) infection in unvaccinated broiler breeder farms in Jeonbuk providence. An enzyme-linked immunosorbent assay (ELISA) and polymerase chain reaction (PCR) had been used to determine antibody titers against MG and MS, and genome of these pathogens, respectively. Seventy five percent of farms were seropositive for MG and 94% of farms were seropositive for MS. In addition, the rate of antibody positive flocks against MG were 65.3% (32/49), while the rate of positive flocks against MS were 84.2% (80/95). The geometric mean antibody titers were and against MG and MS, respectively. Interestingly, none of samples was positive for MG genome by PCR, while 94% (farms), 82% (flocks) and 62.6% (broiler breeder) were positive for MS genome by PCR. These findings suggest that the prevalence of MG or MS infection could be higher than expected. Thus, strict prevention program including vaccination and environmental sanitation should be implemented to avoid disease transmission from breeder to broilers as well as transmission among broilers.
