Transferable IncX3 plasmid harboring bla NDM-1 , ble MBL , and aph(3')-VI genes from Klebsiella pneumoniae conferring phenotypic carbapenem resistance in E. coli.

This is Egypt's first report of a transmissible plasmid co-harboring bla and aph(3')-VI genes. Moreover, the respective plasmid is of great medical concern as it has caused the horizontal transmission of multidrug-resistant phenotypes to the transformant. Therefore, new guidelines should be implemented for the rational use of broad-spectrum antibiotics, particularly carbapenems.
