Meta-analysis on the prevalence of Mycoplasmosis in poultry of India and the World

Mycoplasmosis, is one of the important disease of poultry industry causing huge economic loss. In the present study, the prevalence of Mycoplasma gallisepticum (MG) and Mycoplasma Synoviae (MS) in poultry from India and the World was estimated using meta-analysis from the studies during 2010–2020. The meta-analysis of studies from the world showed that overall pooled prevalence estimates for MS (42.52% CI: 33.16–52.16) is more than MG (39.31% CI: 25.76–53.74). In India also, the pooled estimate for prevalence of MS (29.34% CI: 14.40-46.93) is more than MG (25.97% CI: 19.41–33.11). However, the prevalence of both MG & MS is comparatively less in India than other parts of world. Pooled estimate through serological techniques was more for both MG & MS than other diagnostic methods and ELISA was the most reported diagnostic method followed by other methods including serum plate agglutination assay (SPA), PCR and isolation etc. Zone wise prevalence estimate showed that south zone has comparatively higher prevalence (37.37%) for both MG & MS than other zones in India. Continent wise analysis revealed that African continent has more prevalence for both MG (50.09 % CI: 31.75–68.42) and MS (44.79 % CI: 23.26–67.37) followed by others. Overall, the current study indicates higher prevalence of Mycoplasmosis worldwide including India and other countries emphasizing the importance of strict implementation of biosecurity measures and vaccinations.
