Avian Chlamydia (Chlamydia psittaci), also known as psittacosis, is a bacterial infection that can affect many bird species, particularly parrots.

What are signs of Avian Chlamydia?

Chlamydia psittaci can affect birds in varying ways, from subtle signs to serious illness. Common symptoms may include lethargy, nasal or eye discharge, sneezing, changes in droppings, weight loss, breathing difficulties, or a general decline in activity.

Why testing suspected cases is important for the health of your aviaries

Some birds may show no visible symptoms of Avian Chlamydia. Early detection helps protect not only the infected bird but also the entire flock, as the disease can spread easily. Regular testing supports early intervention, reduces transmission risk, and helps maintain a healthy, thriving aviary.

Sample Collection

For best results, label paper envelopes with the sample number, species and bird ID printed on our order form. Place 2-3 freshly plucked feathers greater than 3cm in length, from each bird into each envelope. Alternatively, blood spotted on card can be provided. Allow any blood at the tip of the feather’s calamus, or on card, to dry before placing in the envelope.
