Chlamydia pneumoniae and chronic pharyngitis.

Chlamydia pneumoniae has been implicated as an etiological agent for both upper and lower respiratory tract infections. We describe 4 cases of chronic pharyngitis where Chlamydia pneumoniae appears to be the etiological agent. All the patients were non-smokers, and had symptoms of more than 6 months' duration. Disease symptoms seemed to resolve following appropriate antibiotic treatment.
