Infection with feline Chlamydia psittaci.

Abstract

A 48 year old man presented with malaise, fever, and progressive mental impairment. Chest radiography showed left lower lobe consolidation. A diagnosis of atypical pneumonia was made and, following treatment with erythromycin and acyclovir, his symptoms rapidly resolved. Asymptomatic biochemical hepatitis persisted for many weeks. Serological examination subsequently showed infection with feline Chlamydia psittaci.
