摘要:

从浮游到生物被膜(BF)生命周期的转变能够促进细菌对非生物表面的黏附,逃避宿主免疫系统,增强其对常见抗菌药物的抗性,在导致人类病原菌感染率不断增加的同时,也大大增加了临床治疗的难度。第二信使环二鸟苷酸(c-di-GMP)对 BF的调控起重要作用。通过直接靶向c-di-GMP信号传导抑制抗菌药物抗性和BF形成意义重大。文章对c-di-GMP在铜绿假单胞菌BF调控中的作用进行综述。

Abstract:

The transition of bacteria from planktonic growth to biofilm(BF) life cycle can promote the adhesion of bacteria to non-biological surfaces,evade host immune system,and increase resistance to common antibiotics. The current BF-forming bacteria have an increasing probability of human infection and greatly increase the energy and time required for treatment and recovery. The second messenger cyclic diguanylate(c-di-GMP) plays a role in the regulation of BF. The research on the treatment of antibiotic-resistant and BF-forming bacteria by directly targeting c-di-GMP signaling has shown promise. Therefore,this review summarizes the effect of c-di-GMP on the regulation of Pseudomonas aeruginosa BF.

Key words: Cyclic diguanylate, Pseudomonas aeruginosa, Biofilm, Regulation
