Pathogenicity studies in poultry with an undefined serotype of Mycoplasma. 1976

D R Wise, and M K Fuller

Pathogenicity trials in poultry are reported with an isolate of mycoplasma, designated 'W8', which is serologically unrelated to Mycoplasma gallisepticum, M synoviae or M meleagridis. W8 killed fowl and turkey embryos when injected into the yold sacs of embryonating eggs. Infection of one-day-old fowls, turkeys and pheasants by the air sac route caused marked growth depression and a high incidence of osteomyelitis of the vertebral column in all species. A large proportion of infected turkeys and a smaller proportion of infected pheasants also developed chondrodystrophic changes of the long bones similar to those of turkey syndrome '65. Infection did not cause mortality or macroscopic air sacculitis. No obvious pathological changes occurred in fowls following W8 infection by the air sac route at two weeks of age and only minimal changes when infection was given at one week. Infection did not appear to spread to in-contact controls. W8 was recovered most frequently and in greatest profusion from the air sacs, tracheas, kidneys and vertebral columns of fowls and turkeys following air sac infection at one day of age.

D009174	Mycoplasma	A genus of gram-negative, mostly facultatively anaerobic bacteria in the family MYCOPLASMATACEAE. The cells are bounded by a PLASMA MEMBRANE and lack a true CELL WALL. Its organisms are pathogens found on the MUCOUS MEMBRANES of humans, ANIMALS, and BIRDS.

D011201	Poultry Diseases	Diseases of birds which are raised as a source of meat or eggs for human consumption and are usually found in barnyards, hatcheries, etc. The concept is differentiated from BIRD DISEASES which is for diseases of birds not considered poultry and usually found in zoos, parks, and the wild.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
