ornithosis

Psittacosis is caused by infection with the bacterium, Chlamydia psittaci, and may also be known as ornithosis.

I'll have to brush up on pullorum, ornithosis, coccidosis, leukosis, perosis, and Ochsner knows how many other -osises and -itises.

The term 'chlamydia' (a cloak) appeared in the literature in 1945, although other names continued to be used, including Bedsonia, Miyagawanella, ornithosis-, TRIC-, and PLT-agents.

In certain contexts, the word "psittacosis" is used when the disease is carried by any species of bird belonging to the Psittacidae family, whereas "ornithosis" is used when other birds carry the disease.

Colonies have been affected by avian cholera and ornithosis, and it is possible that the Common Tern may be threatened in the future by outbreaks of avian influenza to which it is susceptible.
