Abstract

A woman in the first trimester of pregnancy presented with pneumonia and hilar lymphadenopathy after exposure to lambing ewes. She subsequently aborted. Infection with Chlamydia psittaci of ovine origin was confirmed. Pregnant women are susceptible to this infection, which may cause life threatening disease. The patient also had features of sarcoidosis, and the two conditions ran a similar time course. There is a possibility that ovine psittacosis caused an illness indistinguishable from sarcoidosis.
