Case report: Chlamydia pneumoniae pneumonia in an HIV-infected man.

We report a case of an HIV-infected adult with Chlamydia pneumoniae. Our patient presented with a clinical picture suggestive of Pneumocystis carinii pneumonia (PCP), but did not respond to empiric anti-PCP therapy. The diagnosis was eventually confirmed by bronchoscopy and serology. C. pneumoniae pneumonia should be considered in the differential of pathogens that cause interstitial infiltrates in HIV-infected persons.
