Turkey airsacculitis: effect of mixed mycoplasmal infections.
Turkeys experimentally infected with both Mycoplasma meleagridis and a member of the IJKNQR group of avian mycoplasmas developed more-severe air-sac lesions than did turkeys infected with either of these organisms alone. In addition, exudative air-sac lesions were more widely distributed anatomically in turkeys with mixed infections than in those with single infections. Similar studies with Mycoplasma synoviae and M. meleagridis did not indicate a significant increase in the severity of air-sac lesions. Both M. synoviae alone and M. synoviae and M. meleagridis combined produced severe lesions. Perhaps the severity of lesions produced by M. synoviae alone masked any exacerbating effect caused by the mixed infections.
