Extended Spectrum and AmpC beta lactamases among nosocomial klebsiella pneumonia isolates: possible resistance mechanisms

ABSTRACT

Background: hospital acquired Klebsiella pneumoniae may produce Amp C Beta lactamases and/or extended spectrum Beta lactamases [ESBLs] as possible resistance mechanisms among others leading to therapeutic failures and global public health problem. Objectives: to investigate cephalosporin resistance mechanisms that may be referred to AmpC Beta lactamases production whether alone or among ESBLs
