A survey of Mycoplasma infections in domestic poultry.
A survey of mycoplasma infections of chickens, turkeys and ducks was made on tissues from a variety of sources and birds of various ages, and from pipped and dead-in-shell turkey embryos. The tissues examined consisted mainly of respiratory tissue and the cloaca and contents and also a small number of joint lesions and other tissues. From chickens, mycoplasmas were isolated from a total of 138 tissues with Mycoplasma gallisepticum in preponderance. This was followed by M gallinarum, untyped organisms, M synoviae and a number of other mycoplasmas and Acholeplasma laidlawii. From turkeys, poults and embryos, mycoplasmas were recovered from 164 tissues with M meleagridis in preponderance. This was followed by M gallisepticum, serovar I, M synoviae and a number of other species including untyped isolates. From ducks, M gallisepticum and M anatis were recovered in equal numbers. Mycoplasma infections with more than one species occurred in the same tissue in all species of stock but especially in turkeys.
