Intra-abdominal Peptostreptococcus abscess

An intra-abdominal *Peptostreptococcus* abscess is a localized collection of purulent exudate within the peritoneal cavity, retroperitoneum, or visceral abdominal organs, caused in whole or in part by anaerobic gram-positive cocci of the genus *Peptostreptococcus* Defining clinical features include persistent fever, localized or diffuse abdominal pain, leukocytosis, and encapsulated fluid collections detectable on abdominal imaging

This clinical state typically arises in pediatric or adult patients following a breach in gastrointestinal or female genitourinary mucosal barriers—such as from visceral perforation, diverticulitis, appendicitis, abdominal trauma, or surgical interventions—allowing endogenous commensal flora to invade normally sterile peritoneal spaces Pathophysiologically, these infections are predominantly polymicrobial, where *Peptostreptococcus* species act synergistically with other anaerobic and facultativ...

This clinical state typically arises in pediatric or adult patients following a breach in gastrointestinal or female genitourinary mucosal barriers—such as from visceral perforation, diverticulitis, appendicitis, abdominal trauma, or surgical interventions—allowing endogenous commensal flora to invade normally sterile peritoneal spaces

Pathophysiologically, these infections are predominantly polymicrobial, where *Peptostreptococcus* species act synergistically with other anaerobic and facultative enteric organisms to trigger intense localized inflammation, tissue necrosis, and encapsulated pus formation

Defining clinical features include persistent fever, localized or diffuse abdominal pain, leukocytosis, and encapsulated fluid collections detectable on abdominal imaging
