An investigation of outbreak of Mycoplasma gallisepticum in desi chicken was made during winter season. Flock strength of the farm was 245 desi chickens, 10 turkey, 50 quails and 50 pigeons. Among these birds, 15 chickens and 5 pigeons showed clinical signs of gasping, rales and conjunctivitis. Post-mortem examination, revealed congestion of conjunctiva and unilateral and bilateral swelling of infra-orbital sinuses with caseous material. Mycoplasma gallisepticum was confirmed from trachea and choanal swabs by polymerase chain reaction for group specific gene which detected 185 bp and 715 bp amplicon size and outbreak was effectively controlled by treating with Tylosin and strict bio-security measures.
