Emergence of carbapenemase-producing Gram-negative bacteria in Saint Petersburg, Russia.

The emergence and spread of carbapenemase-producing Gram-negative bacteria represents a serious public health concern. Here we show that of 477 Gram-negative isolates collected from 18 hospitals between November 2011 and February 2013 in Saint Petersburg (Russia), minimum inhibitory concentrations (MICs) were greater than the European Committee on Antimicrobial Susceptibility Testing (EUCAST) epidemiological cut-off value of at least one carbapenem antibiotic in 101 isolates (21.2%).
