  • Usually inflammatory and noninfectious.
  • If infectious, frequently polymicrobial. Leading pathogens:
  • Pathogenicity is unclear for organisms cultured in bile/gall bladder unless also recovered in blood.
  • Anaerobes are less significant unless bile duct to bowel anastomosis or fistula present; if so, the most common organisms include Clostridium and Bacteroides species.
  • Pathogenic role of enterococci and anaerobes are otherwise not well defined and empirical coverage not usually required.
