Chronic Endometritis in Subfertile Mares With Presence of Chlamydial DNA

When endometritis becomes chronic in mares, infertility can follow. Among various causative agents, many bacteria are involved, and mono- or mixed-infections are common. In our study, 50 mares with a previous history of subfertility were subjected to clinical and ultrasonographic examination of the reproductive tract, and samples were collected for cytology, histology, bacteriology, and polymerase chain reaction for Chlamydia spp detection. The aim of this work was to highlight the presence of Chlamydia abortus in chronic endometritis of subfertile mares. Endometrial chronic lesions were detected in five of six Chlamydia-positive animals.
