摘要: 抗生素治疗尽管有几十年有效治疗的历史, 但随着越来越多耐/抗药性细菌的出现, 细菌对抗生素的抗药性已成为一个大问题。噬菌体治疗是使用噬菌体作为抗菌剂来感染细菌株系, 它一直是人们倡导的一个很有前途的常规抗生素治疗的替代方案。然而, 由于细菌与噬菌体的协同进化中, 细菌可以通过多种机制获得对噬菌体的抗性。因此, 人们对噬菌体治疗抱有期望的同时, 也关注噬菌体治疗长时间的使用之后, 是否会与抗生素使用之后结果相类似, 导致抗性细菌病原菌感染的治疗困难。综述了细菌-噬菌体协同进化中细菌病原菌对有感染能力的噬菌体是否会产生抗性, 及其在噬菌体治疗中影响的争论, 并展望了噬菌体治疗的潜在前景。

Abstract: Bacterial pathogens have been treated effectively with antibiotics for several decades, but with more and more resistant bacteria appeared, the resistance to antibiotics has become a difficulty issue in antibiotics therapies. Phages therapy, the application of the phages that infect bacterial pathogens as antimicrobials, has been expected and advocated as a promising alternative to conventional antibiotics. However, under the selection of the co-evolution between phages and bacteria, bacterial pathogens can became resistance to the phages by several mechanisms. So, at the same expecting and advocating, should we worry about the problem that whether the phage-treated pathogens will develop to resistance to the phages caused to treat difficulty at last? Here, the arguments about the bacterial pathogens resistance to the phages under the phage-bacterium co-evolution and its effect on the phages therapy were summarized and reviewed, and the phage therapy for control the bacterial pathogen was prospected.
