A northeastern Illinois outbreak last year of infections with Escherichia coli that produces New Delhi metallo-β-lactamase (NDM) was linked with a contaminated endoscope used to perform endoscopic retrograde cholangiopancreatography (ERCP).
In a recent Morbidity and Mortality Weekly Report article, the Centers for Disease Control and Prevention (CDC) cautioned that carbapenem-resistant Enterobacteriaceae (CRE) infections in medical facilities usually are from CRE that produce Klebsiella pneumoniae carbapenemase (KPC). However, NDM-producing CRE may be adding to the burden.
