Ticari broiler ve yumurtacı tavuklarda ELISA ile Mycoplasma synoviae seropozitifliği.

Objective: Mycoplasma synoviae (M. synoviae) is the second most clinically important mycoplasma species, causing significant economic losses to the poultry industry worldwide. The aim of this study is to investigate the presence of antibodies against M. synoviae by indirect ELISA in commercial broiler and commercial layer flocks. Methods: A total of 957 blood samples were collected from vena subcutanae ulnaris under aseptic conditions by random sampling from unvaccinated commercial broiler (n=380) and commercial layer (n=577) flocks in the Central Anatolia Region and their serums were extracted. Anti-M.synoviae antibodies were detected by using commercial indirect ELISA kit. Results: The seropositivity rates were determined 40.76% (n=155) and 54.59% (n=315) in 380 sera from 21 commercial broiler flocks and 577 sera from 33 commercial layer flocks, respectively. Conclusion: In comparison to broilers, M. synoviae infection was shown to be more widespread in poultry breeding, particularly in commercial layer flocks, in the Central Anatolia Region. To avoid economic loss due to M. synoviae in both breeding types, we conclude that it is critical to improve the biosecurity of poultry breeder flocks, conduct regular follow-ups with monitoring studies, especially in breeder flocks, and treat infected herds as soon as possible.
