Mycoplasma species are well-known pathogens of domestic poultry, causing significant economic losses. Mycoplasma synoviae (M. synoviae) can cause respiratory disease, synovitis, or result in a silent infection in chickens and turkeys. A total of 1543 serum samples from non-vaccinated against M. synoviae 65 chicken flocks of different ages from 1 to 70 weeks old were collected. Results show that the seroprevalence of M. synoviae was 56.1% in 2012 and 51.4% in 2013. Mycoplasma seropositivity in laying hens was the highest in summer (79.1%) and lowest in winter (36.0%).
