Trends in antimicrobial susceptibility of Gram-negative isolates from a paediatric intensive care unit in Warsaw: results from the MYSTIC programme (1997-2007)

Abstract

The comparison of antibiotic susceptibility of Gram-negative isolates in 1997 and 2007 showed a trend of increase, and the number of beta-lactamase-producing isolates among Enterobacteriaceae showed a trend of decrease possibly related to changes in antibiotic policy.
