Trends in susceptibility of selected gram-negative bacilli isolated from intra-abdominal infections in North America: SMART 2005-2010

This report summarizes data from the Study for Monitoring Antimicrobial Resistance Trends 2005-2010 to identify trends in susceptibility from intra-abdominal infections in North America. Escherichia coli and Klebsiella pneumoniae were the most frequently isolated pathogens. Extended-spectrum beta-lactamase rates (%) in 2005/2010 for E. coli and K. pneumoniae were 1.7/7.3 and 3.2/13.1, respectively. Ertapenem, imipenem, amikacin, and cefoxitin showed stable susceptibility. (C) 2013 Elsevier Inc. All rights reserved.
