is a zoonotic disease caused by Chlamydophila psittaci.
This compendium provides information about psittacosis and avian chlamydiosis
to public health officials, physicians, veterinarians, the pet bird industry, and others concerned with controlling these diseases and protecting public health.
Infection with Chlamydia psittaci, often referred to as avian chlamydiosis
(AC), is an important cause of systemic illness in companion birds (i.
Results of avian chlamydiosis
testing via PCR were negative.
Performance characteristics of diagnostic tests for avian chlamydiosis
The bacterium also causes avian chlamydiosis
, a disease reported in psittacine birds such as parrots, cockatiels, and parakeets (1-3).
The bird returned for re-examination 3 months after discontinuation of doxycycline and 6 months after the initial diagnosis with no external clinical signs of avian chlamydiosis
or liver disease.
In this study, specific molecular identification of avian chlamydiosis
was performed using a nested PCR on liver tissues, as well as choanal and cloacal swab samples, confirming the presence of Chlamydia psittaci in all of them.
Cockatiels (Nymphicus hollandicus) are popular companion birds and have been implicated in avian chlamydiosis
outbreaks, which affect both birds and people.
In 1999, the US Geological Survey National Wildlife Health Center, Madison, Wisconsin, conducted a diagnostic investigation into a water bird mortality event involving intoxication with avian botulism type C and infection with avian chlamydiosis
at the Benton Lake National Wildlife Refuge in Montana, USA.

The strong association between the start of the treatment for avian chlamydiosis
and the stop of the mortality suggests that other pathogens (in this case, Chlarnydophila) need to be present for this reovirus to cause mortality in budgerigars.
