title: [AmpC beta-lactamases producing bacteria].
abstract: beta-Lactamases are the principal mechanism of bacterial resistance to beta-lactam antibiotics. In recent years, resistance due to production of beta-lactamases including extended-spectrum beta-lactamses, carbapeneases and AmpC beta-lactamses, has risen at alarming rate in clinical isolates of gram-negative bacteria. AmpC beta-lactamses are classified by whether genes locate on chromosome or plasmid. The purpose of this paper is to address the general mechanism involve in AmpC beta-lactamase production and the clinical importance of the enzymes.
