case_images: Macrorestriction analysis of the 4 isolates showed that K. pneumoniae N10-0469 and N10-0506 were closely related, although E. coli N10-0505 and N10-0705 were not (Figure 1).

case_images: PCR and sequencing showed that CMY-6 and NDM-1 were located on an  102-kb plasmid (pNDM-Kp10469), originating from K. pneumoniae N10-0469, and on an  129-kb plasmid (pNDM-Ec10505), originating from E. coli N10-0505 (Figure 2). Incompatibility (Inc) group PCR and fingerprinting showed that both plasmids were related Inc A/C types, indicating possible horizontal transfer in vivo (Figure 2).
