Abstract
A case of acute conjunctivitis in man caused by Chlamydia IOL 207 is described. Chlamydiae were isolated from the eye, and rising titers of type-specific antibodies to Chlamydia IOL 207 in serum and tears demonstrated an etiological role for this agent. Chlamydiae IOL 207 is an atypical chlamydia strain which serological studies suggest is widespread in some communities.
