General Information

Fermenting gram negative rod, of the Enterobacteriaceae family

  • Normal GI flora
  • Most predominant gram negative bacillus

Most common cause of urinary tract infections.

Also common:

  • Intra-abdominal infection/abscess
  • Bacteremia
  • Central line-associated bloodstream infection
  • Prosthetic device infection
  • Gastroenteritis, ranging from travelers diarrhea to invasive infection with hemolytic-uremic syndrome

May require contact precautions if highly resistant i.e. ESBL, carbapenem resistant.

In cases of infections due to ESBL producing organisms, carbapenems may be preferred.

Suspected/confirmed verotoxigenic infection (i.e. 0157-H7) requires notification of Public Health immediately. Antibiotics should be avoided.
