Medical Definition of CRE
: any bacterium of the family Enterobacteriaceae that is resistant to most antibiotics including carbapenems and may cause severe infections (as of the blood or urinary tract) especially in hospitalized patients ◆Bacteria that may become CRE include E.coli and species of the genus Klebsiella (such as K. pneumoniae) … all antibiotic-resistant bacteria arise as bacteria adapt to antibiotics, but the increase in CRE in recent years likely stems at least in part from increased person-to-person transmission.—Tracy Hampton, The Journal of the American Medical Association, 8 Oct. 2014 … the two people who died are among seven patients that UCLA found were infected by the drug-resistant superbug known as CRE—a number that may grow as more patients get tested.—Chad Terhune, The Los Angeles Times, 18 Feb. 2015
