Acinetobacter baumannii displays inverse relationship between meropenem resistance and biofilm production

Abstract

In this study the ability for biofilm production among meropenem (MEM)-resistant and -susceptible Acinetobacter baumannii isolates was verified. MEM susceptibility and biofilm production were screened in 116 isolates. Meropenem-resistant A. baumannii isolates showed a reduced ability to produce biofilms compared to those susceptible to MEM (P<0·0001). The results suggest an inverse relationship between biofilm production and MEM resistance in nosocomial A. baumanni isolates.
