Types CRE can include germs like Escherichia coli (E. coli) and Klebsiella pneumoniae (K. pneumoniae) if they develop resistance to carbapenems. New Delhi metallo-β-lactamase producing carbapenem-resistant Enterobacterales (NDM-CRE) are a type of CRE bacteria that cause infections, which are extremely hard to treat.

Some people use “CRE” to stand for carbapenem-resistant Enterobacterales and some use it to stand for carbapenem-resistant Enterobacteriaceae. Enterobacterales is an order (large group) of many different types of bacteria. It includes three families, or subgroups. One of its subgroups is Enterobacteriaceae, which includes bacteria like:

Patients can become colonized with CRE. Colonization means people carry CRE in or on their bodies but don’t have any illness symptoms. Colonization with CRE can last for many months and even years. People who are colonized can still spread these germs to others. Why are carbapenem-resistant Enterobacterales a problem?

CRE infection (carbapenem-resistant Enterobacteriaceae) is resistant to the antibiotic carbapenem. Symptoms of CRE infections depend upon the organs infected, which may happen if the bacteria escape the intestines. Read about transmission, treatment, and isolation recommendations.

This information explains carbapenem resistant enterobacteriaceae, also called CRE. This resource explains how it spreads and how infections are treated.

Carbapenem-resistant Enterobacteriaceae (CRE) are bacteria that are resistant to carbapenem antibiotics. This may make CRE infections hard to treat. Learn more here.

Carbapenem-resistant Enterobacterales (CRE) are a group of bacteria resistant to a class of antibiotics called carbapenems. CREs are one of the most common causes of bacterial infections in both healthcare and community settings. Enterobacterales are a family of bacteria that include Klebsiella species and Escherichia coli (E. coli). These bacteria normally live in the human intestines (gut ...
