Mycoplasma Meleagridis Infection

Mycoplasma meleagridis (MM) is a pathogen found predominately in turkeys. It is an egg-transmitted disease that primarily causes airsacculitis in young birds that were breed from infected breeders.

MM is transmitted from hen to offspring, which increased incidents as the flock ages. MM can also be introduced from contaminated clothing or equipment from flock owners or visitors.
