NDM-1-Producing Citrobacter freundii, Escherichia coli, and Acinetobacter baumannii Identified from a Single Patient in China

Abstract

ABSTRACTWe identified New Delhi metallo-β-lactamase (NDM-1)-producingCitrobacter freundiiGB032,Escherichia coliGB102, andAcinetobacter baumanniiGB661 in urine and stool samples from a single patient in China. Plasmid profiling and Southern blotting indicated thatblaNDM-1from GB032 and that from GB102 were likely located on the same plasmid, whileblaNDM-1from GB661 was located on a very large (>400-kb) plasmid. This case underscores the broad host range ofblaNDM-1and its potential to spread between members of the familyEnterobacteriaceaeandA. baumannii.
