Press Enter to show all options, press Tab go to next option


Enterobacteria is a group of bacteria commonly found in human and animal intestines. Common Enterobacteriaceae include E. coli, Klebsiella spp. and Enterobacter spp. Enterobacteriaceae resistant to broad-spectrum antibiotics (carbapenems) are called CRE (carbapenem-resistant Enterobacteriacea).

CRE that produce carbapenemase (CP-CRE) can transmit resistance from one Enterobacteriaceae to another. When a lab identifies a CRE, they forward the specimen to Washington State Public Health Lab to determine if it is a CP-CRE.

Report confirmed cases of CP-CRE within 24 hours.

CP-CRE is a rare disease of public health significance. Call (253) 798-6534 or use the Notifiable Conditions Fax Form to report confirmed cases within 24 hours. For more information, see our Report Notifiable Conditions page.
