ResumoA serological investigation of Mycoplasma gallisepticum (MG) infection in chicken was conducted in the greater Rajshahi district of Bangladesh on 115 flocks during the period from July 2006 to June 2007. A total of 575 sera samples were collected and tested by serum plate agglutination (SPA) test using Mycoplasma gallisepticum antigen (Nobilis MG, Intervet International B.V. Boxmeer-Holland) to determine specific antibodies in different flocks. The overall seroprevalence of MG infection in different flocks was recorded as 55.13%. Seroprevalence of MG infection was found significantly (p < 0.05) higher during winter season (61.48%) than in summer (47.74%). Again this was recorded in different age groups, with significantly (p < 0.01) higher occurrence in young (72.72%) compared to adult (44.00%). On the other hand, the seroprevalence of MG infection was found little (p>0.05) higher in large flocks (62.86%) in comparison to small flocks (52.00%). It has been found that MG infection is still an important disease problem in chickens in Bangladesh.
