[Psittacosis: report of 7 cases]

The development and systematic use of microserological techniques have allowed to identify the etiology of a higher number of respiratory diseases, that could hardly have been considered some years ago and that now are known to play a more common role in clinical practice than usually thought. In the present study, the clinical, radiological and epidemiological features of seven patients are reported; they were seen in our health center during a 16 month period and the diagnosis of Chlamydia psittaci pneumonia was made by serological studies. All patients were treated with erithromycin, with favorable clinical and radiological outcome. Psittacosis is a condition that should be considered as a cause of community acquired pneumonia even in the absence of suggestive epidemiological background.
