Intestinal spirochaetosis mimicking acute appendicitis with review of the literature.

Human intestinal spirochaetosis is a well-established micro-organism existing in the colon. It is less commonly seen in the appendix, and rarely presents as acute appendicitis. We present a case of a man presenting with symptoms consistent with acute appendicitis. The literature on spirochaetosis presenting as acute appendicitis is also reviewed. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.
