Peptostreptococcus peritonitis

*Peptostreptococcus* peritonitis is an intra-abdominal infection characterized by inflammation of the peritoneum caused by anaerobic, Gram-positive cocci of the genus *Peptostreptococcus* (or closely related reclassified Gram-positive anaerobic cocci) This condition primarily affects the abdominal cavity following a breach of mucosal barriers—such as from hollow viscus perforation, bowel ischemia, surgical intervention, or peritoneal dialysis catheter contamination—allowing commensal organisms f...

This condition primarily affects the abdominal cavity following a breach of mucosal barriers—such as from hollow viscus perforation, bowel ischemia, surgical intervention, or peritoneal dialysis catheter contamination—allowing commensal organisms from the gastrointestinal or genitourinary tracts to enter the peritoneal space

It typically presents as a polymicrobial infection, frequently alongside facultative anaerobes and enteric Gram-negative bacilli Defining clinical and pathophysiologic features include severe abdominal pain, rebound tenderness, fever, leukocytosis, and the accumulation of purulent peritoneal fluid with a propensity toward intra-abdominal abscess formation
