Mcr-1 gene seen in K. pneumoniae bacteria

Increased prevalence of mcr-1 gene that confers multidrug-resistance has now been reported in Klebsiella pneumoniae bacteria, increasing the fear of infection by pan drug-resistant bugs.

A study published in Antimicrobial Agents and Chemotherapy found that about 10% of the K. pneumoniae bacteria studied were resistant to colistin.
During January–February 2016, a total of 200 K. pneumoniae isolates from pus, blood, sputum, and urine were studied. Of this, 21 were resistant to colistin, and further screening revealed that four harboured mcr-1 gene.
