Genetic detection of AmpC beta-lactamase among gram negative isolates "A Single Center Experience''.

The misuse of β-Lactam antibiotics results in major problem, microbial resistance against these antibiotics by expression of β-lactamases, facing its use. AmpCs are one of the β-lactamases which confer resistance to penicillins, cephalosporins, cephamycins, and aztreonam, and are not affected by classic β-lactamase inhibitors. Plasmid-mediated AmpC β-lactamases pose a major challenge to infection control because the AmpC gene can be expressed in larger quantities and has a high transmissibility to other bacterial species.
