Abstract |
The β-lactam antibiotics play an important role in antibacterial chemotherapy because of their high efficacy combined with a lack of toxicity exception of allergy. First article concerning β-lactamase in Bacillus coli was reported by Abraham and Chain by 1940. Now, most of clinical physicians, clinical technologists, pharmacists and nurses have known that resistance to β-lactams in Gram-negative organisms are associated with plasmid which are easily transferred among species. β-Lactam resistance caused by β-lactamase is increasingly associated with plasmidic AmpC, extended-spectrum β-lactamases (ESBLs) and carbapenemases, specifically the CMY-family of AmpC, the CTX-M-family of ESBLs, the KPC family of serine carbapenemases, and the IMP, VIM and NDM-1 metallo-β-lactamases. Classification of the β-lactamase is quite complicated, because more than 1500 β-lactamases have been reported now. In this review, I will try to update and explain of the classification for β-lactamase. |
