Increasing carbapenem-resistant gram-negative bacilli and decreasing metallo-β-lactamase producers over eight years from Korea

Abstract

The trends and types of carbapenemase-producing Gram-negative bacilli were analyzed from clinical specimens collected between 2005 and 2012 at a Korean teaching hospital. The proportions of carbapenem-resistant Acinetobacter spp. increased markedly to 66%. Metallo-β-lactamase producers significantly decreased and the majority shifted from the blaVIM-2 type to the blaIMP-1 type.
