Intra-abdominal Bacteroides abscess

An intra-abdominal *Bacteroides* abscess is a localized, walled-off collection of purulent exudate, necrotic debris, and microorganisms within the peritoneal cavity, retroperitoneum, or visceral abdominal organs, caused primarily or synergistically by anaerobic gram-negative bacilli of the genus *Bacteroides* This clinical state typically arises in adult and pediatric surgical or hospitalized populations secondary to disruption of the gastrointestinal mucosal barrier following viscus perforation...

Pathophysiologically, capsular polysaccharides of *Bacteroides* species, particularly *Bacteroides fragilis*, directly promote mesothelial adhesion, elicit host peritoneal inflammation, and drive fibrous pseudo-capsule formation

Patients typically present with localized or diffuse abdominal pain, leukocytosis, and persistent fever, often in the setting of polymicrobial anaerobic-aerobic peritonitis
