eResistance to carbapenems in Enterobacteriaceae is a clinical problem of growing significance. Difficulty in treating multidrugresistant Gram-negative organisms with conventional antibiotics has led to a renewed and increasing use of polymyxin compounds, such as colistin. Here, we report the isolation of carbapenem-and colistin-resistant Enterobacter cloacae from a polymicrobial lower extremity wound in an ambulatory patient. Whole-genome sequencing demonstrated the presence of chromosomal bla IMI-1 and bla AmpC , as well as numerous efflux pump genes.

Page 3142, Table 2: the annotation of two efflux pumps as mex was incorrect and the bla AmpC gene was improperly labeled as "class A." The corrected Table 2 is shown below.
