Intra-abdominal Eubacterium abscess

An intra-abdominal *Eubacterium* abscess is a localized, walled-off collection of purulent exudate within the peritoneal cavity, retroperitoneum, or visceral abdominal organs caused by or involving anaerobic, non-spore-forming Gram-positive bacilli of the genus *Eubacterium* Typically occurring as part of a complicated, polymicrobial intra-abdominal infection, it develops when endogenous gastrointestinal flora breach the mucosal barrier following bowel perforation, abdominal trauma, inflammatory...

Typically occurring as part of a complicated, polymicrobial intra-abdominal infection, it develops when endogenous gastrointestinal flora breach the mucosal barrier following bowel perforation, abdominal trauma, inflammatory diseases such as diverticulitis or appendicitis, or surgical contamination

Typically occurring as part of a complicated, polymicrobial intra-abdominal infection, it develops when endogenous gastrointestinal flora breach the mucosal barrier following bowel perforation, abdominal trauma, inflammatory diseases such as diverticulitis or appendicitis, or surgical contamination

Affected patients generally present with systemic signs of infection, such as fever and leukocytosis, alongside focal abdominal pain, localized tenderness, and occasionally a palpable abdominal mass

Pathophysiologically, the encapsulated cavity forms a hypoxic and acidic microenvironment that supports anaerobic bacterial persistence and cellular necrosis while impeding host immune clearance and systemic antimicrobial penetration
