Serious poultry infections including Mycoplasma synoviae (MS) & Mycoplasma gallisepticum (MG) can cause significant financial losses worldwide. Poultry production and health are negatively impacted by MG and MS infections. This study used Indirect ELISA to find out how common MG & MS infections were in layer hens. Between April 2025 and July 2025, 100 samples were taken from layer hens that had salpengitis. Of them, 60 salpengitis samples were positive by ELISA. MG antibodies were found in 47% and MS antibodies in 29% of the hens, and MG seroprevalence was considerably greater than MS .Additionally, Mycoplasma gallisepticum was detected alone in 31% of the hens, which was substantially higher than the MS infection rate of 13% and 16% of the chicks that had both MG & MS infections simultaneously. Commercial layers aged 40 weeks had the lowest infection rate (45.7%), while those aged 57 weeks had the highest infection rate. The age group of 55 weeks old had the highest percentage of MG infection (53.3%), whereas commercial layers aged 60 weeks had the highest prevalence of MS infection. These findings indicate that Mycoplasma gallisepticum MG antibodies are more common than MS, that MG is more common as a single infection than MS, and that the risk of infection rises with hen age.
