The anaerobic spirochete causes intestinal spirochetosis, characterized by the intimate attachment of bacterial cells to the colonic mucosa, potentially leading to symptoms such as diarrhea, abdominal pain, and weight loss. Despite the clinical significance of infections, the mechanism of the interaction between and the colon epithelium is not known. We characterized the molecular mechanism of the -epithelium interaction and its impact on the epithelial barrier during infection.

Human intestinal spirochetosis (HIS) is a rare occurrence. We present an interesting case study on an asymptomatic over-60-year-old male who was incidentally discovered to have HIS following a colonoscopy that was conducted for his positive fecal occult blood test (FOBT). Histopathology of the colonic biopsy proved the presence of human intestinal spirochetosis; however, as he was asymptomatic, treatment was not initiated in his case.

Objectives: This study aims to determine what pathologic and clinical factors differentiate Brachyspira species that may be useful to clinicians and pathologists.
Methods: We identified 21 studies of Brachyspira infection with individual patient information (n = 113) and conducted a pooled analysis comparing each species.
Results: There were differences in the pathologic and clinical profiles of each Brachyspira species.

Human intestinal spirochetosis (HIS) is an uncommon disease characterized by the colonization of spirochetes in the colorectal mucosa and is most often found in individuals who are positive for human immunodeficiency virus (HIV) and in homosexual men. Although HIV is known to cause a variety of infectious colitis, the prevalence has significantly declined with antiretroviral therapy. Intestinal spirochetosis, however, remains meaningful as it can be an infectious cause of colonic ulcerations even with well-controlled HIV.
