细菌感染是临床感染性疾病中最主要的原因,在成人中80％左右的感染均是由细菌引起的。由于细菌的细胞结构和生理代谢过程远比病毒复杂,与哺乳类动物细胞又有明显的区别,在开发治疗药物方面容易找到突破口,做到既有效杀灭细菌,又不会破坏人体的细胞结构,在治疗难度上远低于病毒性感染。特别是随着抗生素类药物的发现和广泛应用,以往困扰人类的细菌感染性疾病基本得到了有效的控制。 Bacterial infections are the most common cause of clinical infectious disease, and about 80% of infections in adults are caused by bacteria. Because of bacterial cell structure and physiological metabolic processes far more complex than the virus, and mammalian cells and there are significant differences in the development of therapeutic drugs is easy to find a breakthrough, so that both effectively kill bacteria, without undermining the body’s cell structure , Much lower than the viral infection in the treatment of difficulty. In particular, with the discovery and widespread use of antibiotics, bacterial infectious diseases that have plagued humans in the past have been effectively controlled.
