Mycoplasma gallisepticum

Mycoplasma are a genus of tiny bacteria known for causing immunosuppression and respiratory disease in their affected host. The Mycoplasma genus is unique to other bacteria in that they lack a cell wall around their cell membrane. This provides them the ability to resist many common antibiotics that work by targeting cell wall synthesis. Over 100 species of Mycoplasma have been reported, each infecting a specific group of animal species that serve as a host. Mycoplasma gallisepticum (MG) is one of the most significant pathogens that affects poultry.

Survival in the environment
Mycoplasma is inactivated by exposure to UV.

Susceptibility to disinfectants: Phenolic disinfectants, 1% sodium hypochlorite, 70% ethanol, formaldehyde, glutaraldehyde, iodophore, and peracedic acid are effective against Mycoplasma spp.
