Re: Evidence for an association between Chlamydia psittaci and ocular adnexal lymphomas.

Abstract
Ferreri et al. ( 1 ) recently reported that patients with ocular adnexal lymphoma had a high prevalence of Chlamydia psittaci infection in both tumor tissues and peripheral blood mononuclear cells. More recently, one study reported a similar prevalence of the infection in a Korean patient series ( 2 ) , whereas three other studies did not observe such an association ( 3 – 5 ) .
