[Keratoconjunctivitis caused by Chlamydia psittaci].

A 25-year-old female patient suffering from acute follicular keratoconjunctivitis with epithelial and subepithelial corneal infiltrates was examined. Antibodies of the IgM class directed against C. psittaci were found. Infection due to C. trachomatis was ruled out by serology (ELISA) and negative isolation attempts. The patient's cat had rhinitis and conjunctivitis and a positive C. psittaci specific IgM antibody titer. Systemic application of tetracycline resulted in fast resolution of symptoms in both the patient and her cat.
