一般描述

Chemical structure: tetracycline

生化/生理作用

作用机制：四环素通过细胞膜中的 proin 通道被动扩散，与 30S 核糖体结合，并通过阻止氨酰基 tRNA 进入 mRNA-核糖体复合物上的受体位点来抑制蛋白质合成。它也与细菌的 50S 核糖体亚基结合，改变膜并导致细胞内成分从细菌细胞中泄漏。通过洗涤可以逆转抑制作用，这表明起到抗菌作用的是可逆结合的抗生素，而不是不可逆结合的药物。

耐药性机制：这种作用通过细胞壁通透性的丧失而失活。

抗菌谱：包括对革兰氏阳性和革兰氏阴性细菌的广泛抗菌活性。

其他说明

Keep container tightly closed in a dry and well-ventilated place. Keep in a dry place

Resistance to tetracycline emerged soon after its discovery six decades ago. Extensive clinical and non-clinical uses of this class of antibiotic over the years have combined to select for a large number of resistant determinants, collectively termed the tetracycline resistome.

A survey carried out in 2005 among members of a healthy population of children living in Bolivia and Peru revealed that fecal carriage of Escherichia coli strains resistant to expanded-spectrum cephalosporins was remarkably increased compared to that observed in the

Surveillance of gonococcal antimicrobial resistance and the molecular characterization of the mechanisms underlying these resistance phenotypes are essential in order to establish correct empirical therapies, as well as to describe the emergence of new mechanisms in local bacterial populations. To
