Molecular Prevalence and Seroprevalence of Mycoplasma gallisepticum and M. synoviae in Indian Poultry Flocks

Mycoplasma gallisepticum and M. synoviae are the two important pathogens affecting poultry worldwide and responsible for huge economic losses to the poultry industry. Here, we studied the prevalence of M. gallisepticum and M. synoviae in poultry flocks from different geographical regions in India. Prevalence of M. synoviae and M. gallisepticum as 33.0% and 11.65% was observed in samples from live birds of different states and 25.98% and 9.45% of samples were positive for M. synoviae and M. gallisepticum in post mortem examined birds of a single farm. ELISA results showed seroprevalence of 52.1 and 32.6%, respectively of M. synoviae and M. gallisepticum in a total of 635 samples. The PCR and ELISA results revealed an overall higher prevalence of M. synoviae than M. gallisepticum in live birds from different states and in dead birds with Chronic Respiratory Disease and the results shows the urgent need for adoption of better control measures against M. synoviae including vaccination.
