In order to investigate seroprevalence of turkey's chlamydiosis in Khuzestan province, 270 turkeys, of different sex and ages from different parts of Khuzestan province were bleed and their sera were tested for antibodies to Chlamydophila psittaci using an enzyme-linked immunosorbent assay (Immunocomb-ILS). According to results the seroprevalences of chlamydiosis were 58.9% in tested turkeys. Chi square test showed that the prevalence were significantly lower in young, under 6 months (25%) than adult's turkeys (66%) and in cold (68.9%) than warm (49.3%) months (p<0.005). In Khuzestan, highest (85.7%) and lowest (31.42%) prevalences were in Shoshtar and Haftgel respectively. It is inferred that C. psittaci is widespread in turkey's populations in Khuzestan and further attempts for definitive diagnosis by isolation of its etiologic agents are recommended.
