30.1 Epidemiologic Review

30.1.1 Disease Information

Overview: Carbapenem resistant Klebsiella is a bacterium found in the gastrointestinal tract that is resistant to one or more carbapenem antibiotics. Carbapenemase-producing bacteria make enzymes called carbapenemases that inactivate carbapenems and other β-lactam antibiotics, including penicillins and cephalosporins. The five most common carbapenemases are KPC, NDM, VIM, OXA, and IMP.

Symptoms: Symptoms vary depending on the type of disease and some people may be asymptomatic.

Transmission: Person-to-person contact by infected healthcare personnel or by contaminated medical equipment.

Treatment: Treatment varies with each isolate. Some cases may be susceptible to a small number of antibiotics while others are pan-resistant, meaning no treatment is available.

Prevention Proper hand hygiene, use of personal protective equipment and environmental cleaning practices help reduce the spread of disease. Practicing antibiotic stewardship could help in reducing antibiotic resistance.
