Genetic typing of carbapenem-resistant Enterobacter cloacae identified from patients at Sanford Health in Fargo, North Dakota, USA. Repetitive sequence–based PCR was used. The dendrogram at left displays the percentage similarity among band patterns shown at right. Isolate numbers ND 1, ND 4–5, ND 7–14, and ND 18–23 indicate Klebsiella pneumoniae carbapenemase (KPC) 3–producing E. cloacae isolates isolated during December 2011–December 2012; ND A–C indicate KPC-3–producing E. cloacae isolated du

The dendrogram at left displays the percentage similarity among band patterns shown at right. Isolate numbers ND 1, ND 4–5, ND 7–14, and ND 18–23 indicate Klebsiella pneumoniae carbapenemase (KPC) 3–producing E. cloacae isolates isolated during December 2011–December 2012; ND A–C indicate KPC-3–producing E. cloacae isolated during 2010. All KPC-3–producing E. cloacae isolates share >97% similarity, indicating a clonal strain. ND 15 and 16 are E. cloacae, and ND 17 is E. aerogenes, genetically distinct and without carbapenemases.
