Emerge of blaNDM-1 and blaOXA-48-like harboring carbapenem-resistant Klebsiella pneumoniae isolates from hospitalized patients in southwestern Iran

This is the first identification of blaNDM-1 and blaOXA-48-like in K. pneumoniae in Southwestern Iran and the highest reported prevalence of blaNDM in this bacterium from Iran. Since carbapenem-resistant isolates containing New Delhi metallo-beta-lactamase 1 (NDM-1) were almost resistant to all the tested antibiotics, the resistance due to this gene may be increased in the near future as a potential health threat.
