Cholangitis
PATHOGENS
- Frequently polymicrobial, usually gastrointestinal flora.
- E. coli (22-50%), Klebsiella species (15-20%), Enterobacter species (5-10%)
- Enterococcus (10-20%) and anaerobes (often of unclear relevance)
- The pathogenic role of enterococci and anaerobes is not well defined, and empirical coverage for these organisms is not usually required.
- Resistant pathogens may be encountered in patients with healthcare-associated infections or recent antibiotic use; empirical coverage should be adjusted accordingly.
