In conclusion, the drug resistance is directly related to the clinical use time and range of b-lactam antibiotics.

The b-lactam antibiotic including penicillins, cephalosporins, cephamycins, monocyclic lactams and other atypical class refers to a large class of antibiotics containing the b-lactam ring structure.

coli to b-lactam antibiotic is that it can produce ESBLs which can destroy the b-lactam ring through hydrolysis or non-hydrolysis and inactivate the antibiotic (George et al.

To monitor the b-lactam antibiotics resistance and to find out the mechanisms as well as to guide clinical medication, this study detected the b-lactam antibiotics resistance and ESBLs gene of avian E.

This is a big problem in studying b-lactam resistance, as b-lactam resistance can increase due to inappropriate b-lactam use.

Objective: The production of AmpC b-lactamases is one of the common mechanisms of b-lactam drugs resistance.

AmpC b-lactamase producing organisms are major clinical concern because they are usually resistant to all b-lactam drugs, except for cefepime, cefpirome and carbapenems.
