Serological and bacteriological study of avian mycoplasmosis in the Cap Bon region of Tunisia

Abstract

A Mycoplasma gallisepticum and M. synoviae seroepidemio-logical and bacteriological survey was performed on hens and turkeys in a region of Tunisia with heavy poultry concentration. During the survey 63 farms were visited and 780 blood samples and tracheal swabs were collected, and antibodies directed against M. gallisepticum, M. synoviae and M. meleagridis were searched. The bacteriological investigation concerned M. gallisepticum and M. synoviae. Serology of the flocks revealed 36.5, 19 and 0% infection rates with M. gallisepticum, M. synoviae and M. meleagridis, respectively. There were 15 flocks bacteriologically positive for M. gallisepticum and 5 for M. synoviae, i.e. 23.8 and 7.9% of the farms surveyed, respectively.
