Chla·myd·o·phil·a psit·ta·ci

(klă-midō-filă si-tasī)
Organisms that resemble C. trachomatis but do not produce glycogen. Various strains of this species cause psittacosis in humans and ornithosis in birds. Also called Chlamydia psittaci (q.v.).

Chlamydophila psittaci

A species of Chlamydophila common in birds and animals. Pet owners, pet shop employees, poultry workers, and workers in meat-processing plants are frequently exposed to C. psittaci.

Symptoms

After an incubation period of 5 to 15 days, nonspecific symptoms (e.g., malaise, headache, fever) develop; progression to pneumonia is serious and may be fatal. Alternatively, the disease may resemble infectious mononucleosis with fever, pharyngitis, hepatosplenomegaly, and adenopathy. Severity may vary from inapparent to mild to fatal systemic disease.

Prognosis

The fatality rate is approx. 20% in untreated patients.

Treatment

Treatment consists of tetracycline or doxycycline for 10 to 21 days.

Chlamydophila

a genus of obligately intracellular bacteria in the family Chlamydiaceae. Members were previously in the genus Chlamydia.

Chlamydophila abortus
causes enzootic abortion of ewes. Previously called Chlamydia psittaci.
Chlamydophila caviae
causes conjunctivitis in guinea pigs. Previously called Chlamydia psittaci.
Chlamydophila felis
cause of upper respiratory tract disease, principally involving conjunctivitis, in cats. Also recovered from the reproductive tract, where its pathogenic significance is uncertain. Previously called Chlamydia psittaci.
Chlamydophila pecorum
causes sporadic bovine encephalomyelitis, but also associated with enteritis, polyarthritis, pneumonia and conjunctivitis in ruminants, and reproductive tract disease in koalas. Previously classified as Chlamydia psittaci and C. pecorum. Conjunctivitis in sheep previously attributed to Colesiota conjunctivae.
Chlamydophila pneumoniae
different biovars infect horses, koalas and humans. Pathogenic significance in koalas and horses is uncertain, but in humans it is a significant cause of pneumonia. Previously classified as Chlamydia psittaci and C. pneumoniae.
Chlamydophila psittaci
cause of psittacosis and ornithosis, systemic disease of psittacine and other avian species, including domestic poultry. Zoonotic. Previously called Chlamydia psittaci.
