Immunoperoxidase localization of chlamydial antigens in acute salpingitis.

Seventy surgically excised fallopian tubes in which there was originally a diagnosis of acute salpingitis were reviewed histologically and screened for chlamydial antigens by the immunoperoxidase technique. Chlamydial antigens were localized within tubal epithelial cells in two of the 70 cases (3%). Endometrial specimens from these two patients were also positive for chlamydial antigens. There was no definite correlation between the histologic features of the salpingitis and chlamydial immunoperoxidase positivity.
