Compendium of psittacosis (chlamydiosis) control, 1997. Centers for Disease Control and Prevention

Infection with Chlamydia psittaci, often referred to as avian chlamydiosis (AC), is an important cause of systemic illness in companion birds (i.e., birds kept by humans as pets) and poultry. Infection can be transmitted from infected birds to humans. In humans, infection caused by C. psittaci is referred to as psittacosis, which can result in fatal pneumonia. This compendium provides information on AC (also known as psittacosis, ornithosis, and parrot fever) and psittacosis (also known as parrot disease, parrot fever, and chlamydiosis) to public health officials, veterinarians, physicians, the companion-bird industry, and others concerned with control of the disease and protection of public health. These recommendations provide effective, standardized disease control procedures for AC in companion birds and will be reviewed and revised as necessary.
