bacterial organisms that resemble Chlamydia trachomatis, but that form loosely bound intracytoplasmic microcolonies up to 12 mcm in diameter, do not produce glycogen in sufficient quantity to be detected by iodine stains, and are not susceptible to sulfadiazine. Various strains of this species cause psittacosis in humans and ornithosis in nonpsittacine birds; pneumonitis in cattle, sheep, swine, cats, goats, and horses; enzootic abortion of ewes; bovine sporadic encephalomyelitis; enteritis of calves; epizootic chlamydiosis of muskrats and hares; encephalitis of opossum; and conjunctivitis of cattle, sheep, and guinea pigs.
Chlamydia psittaciThe agent that causes psittacosis, see there.
An organism related to bacteria that infects some types of birds and can be transmitted to humans to cause parrot fever.
Mentioned in: Parrot Fever
a genus of bacteria in the family Chlamydiaceae previously comprising three species: C. trachomatis, C. pneumoniae and C. psittaci. Following reclassification in 1999, C. psittaci, C. pecorum and C. pneumoniae are now in the genus Chlamydophylia. C. trachomatis remains in the genus Chlamydia, but the mouse and swine strains previously included are now classified in two new species.
associated with respiratory tract infections in mice and hamsters. Previously classified as C. psittaci.

associated with enteritis, pneumonia and conjunctivitis in pigs. Previously classified as C. psittaci.
