Bacteroides peritonitis

Bacteroides peritonitis is an acute intra-abdominal infection characterized by inflammation of the peritoneum caused by anaerobic, gram-negative bacilli of the genus *Bacteroides*, most prominently *Bacteroides fragilis* Pathophysiologically, the condition often occurs as part of a synergistic polymicrobial infection where the organism's capsular polysaccharides promote intense local inflammation, leukocyte influx, and intra-abdominal abscess formation

Typically presenting as secondary peritonitis, it develops following a disruption of gastrointestinal mucosal integrity—such as from bowel perforation, appendicitis, diverticular disease, trauma, or surgical contamination—which allows enteric flora to spill into the sterile peritoneal cavity Affected individuals commonly manifest localized or diffuse severe abdominal pain, rebound tenderness, muscular guarding, fever, and a risk of progressing to systemic sepsis
