ABSTRACT
Carbapenem-resistant Klebsiella pneumoniae and Escherichia coli, multidrug-resistant Pseudomonas aeruginosa and vancomycin-resistant Enterococcus faecium were isolated from a single patient. The patient came to Japan for advanced medical treatment after having undergone laparoscopic cholecystectomy and hospitalization in Vietnam. Whole-genome sequence analysis revealed that K. pneumoniae harbored blaOXA-48 that was found on a Col156 -type small plasmid, E. coli harbored blaNDM-5 and P. aeruginosa harbored both blaNDM-1 and 16S rRNA methyltransferase (rmtB). To the best of our knowledge, this is the first report of detection of K. pneumoniae harboring blaOXA-48 on a Col156-type small plasmid in the world and P. aeruginosa coharboring genes encoding NDM-1 and RmtB in Japan.
