摘要
β-内酰胺类抗生素是临床上广泛应用的一类抗生素,其抗菌机制是通过抑制细菌的细胞壁合成来达到杀菌的效果。然而,由于β-内酰胺类耐药基因在菌株间的广泛传播,导致β-内酰胺类抗生素的使用受到了极大的挑战。其中,blaTEM耐药基因是β-内酰胺酶的主要编码基因之一,迄今已鉴定出243个blaTEM亚型,其在抗生素耐药性研究中具有极其重要的地位。本文将从blaTEM基因的发现、结构及启动子,blaTEM基因的分布和传播,blaTEM基因的耐药机制以及研究现状进行综述,旨在为细菌中β-内酰胺类耐药基因亚型的研究提供借鉴。
β-lactam antibiotics are a class of antibiotics widely used in clinical treatment.The antibacterial mechanism of them is to inhibit the cell wall synthesis of bacteria.However,the widespread ofβ-lactam resistance genes among bacteria has posed a great challenge to the use ofβ-lactam antibiotics.One of the main genes encodingβ-lactamase is blaTEM,and 243 subtypes of it have been identified to date.Studying blaTEM gene is of great significance in antibiotic resistance research.This review focused on the discovery,structure,promoter,distribution,spread,antibacterial mechanism and research status of blaTEM gene,hoping to provide reference for further research on the subtypes ofβ-lactam resistance genes in bacteria.
