A 12 year (1998-2009) antibiotic resistance surveillance of Klebsiella pneumoniae collected from intensive care and urology patients in 14 Dutch hospitals

Objectives We evaluated the changes in antibiotic resistance from 1998 to 2009 of Klebsiella pneumoniae isolated from the intensive care units (ICUs) and urology services of 14 Dutch hospitals and the consequences for empirical therapy. Methods Quantitative antibiotic susceptibility testing of K. pneumoniae was performed in a central laboratory using a microbroth dilution method. Breakpoints were as defined by the European Committee on Antimicrobial Susceptibility Testing (EUCAST). The prevalence of extended-spectrum β-lactamase (ESBL)- and carbapenemase-producing isolates was determined. Resu... Mehr ...
