Interpretive Summary:

Technical Abstract: Avian chlamydiosis is a disease caused by the bacterium Chlamydophila psittaci. There are six known serotypes infecting both wild birds and domestic poultry. Wild birds are thought to be the natural reservoir for most of the serotypes and serve as a source of infection for domestic poultry and humans. Chlamydiosis is widespread in wild birds with diagnosis having been made in over 400 species. The disease in birds varies greatly from asymptomatic to death. Death losses are unusually not noted; however, die-offs of gulls, doves, and waterbirds have drawn attention. Differential diagnosis is becoming more important as a number of birds tested for West Nile virus have been found infected with Chlamydiae. This chapter covers the classification, host range, and transmission of the organism. It also covers the clinical and pathological signs, diagnosis, and control in birds.
