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
