Infections of the organism can yield significant losses in performance and associated economics to all sectors of the poultry industry. In this paper, potential and realized effects of MG on the poultry industry are discussed along with currently available and developing control methods. Available m...

Identification of Strain-Specific Sequences That Distinguish a Mycoplasma gallisepticum Vaccine Strain from Field Isolates

Despite attempts to control avian mycoplasmosis through management, vaccination, and surveillance, Mycoplasma gallisepticum continues to cause significant morbidity, mortality, and economic losses in poultry production. Live attenuated vaccines are commonly used in the poultry industry to control avian mycoplasmosis; unfortunately, some vaccines may revert to virulence and vaccine strains are g...

S OF PAPERS 235 larly and intranasally with virulent Ark virus on day 30. Necropsy was performed on day 35 and clinical signs, sera, and virus detection were analyzed. Vaccine replication was not detected in a significant number of broilers until day 24 post vaccination and SPF chickens until day 28 post vaccination. Following challenge, 14 of 20 SPF and 9 of 20 broiler chickens tested positive...
