The purpose of this study is to clarify clinicopathologic features of IS in Japan with special reference to HIV infection status and species types. We retrospectively reviewed 5,265 consecutive colorectal biopsies from 4,254 patients examined from January 2008 to October 2011. The patients comprised 55 HIV-positive (1.3%) and 4,199 HIV-negative (98.7%) persons. The diagnosis of IS was based on the histologic features of IS. The length of the spirochetes was measured by digital microscopy because causative spirochetes have been reported to be Brachyspira aalborgi, measuring 2 to 6 µm, or Brachyspira pilosicoli, measuring 4 to 20 µm. Among 55 HIV-positive patients, 53 (96%) are men and 2 (4%) are women with a mean age of 48 years (range, 26-73 years). Among 4,199 HIV-negative patients, 2,505
