Abstract

Abstract: The aim of this study was to investigate the inhibitory effects of antimicrobial peptides Temprine-La(S)(T-La(S)),Temprine-La(FS) (T-La(FS)),RGD-T-La(S) and RGD-T-La(FS) on biofilm formation of Streptococcus suis type 2 (SS2).The biofilm formation ability of SS2 was detected by crystal violet staining (CV).The MBIC and MBEC of antimicrobial peptides against SS2 biofilm were determined by microdilution method.Crystal violet staining and scanning electron microscopy (SEM) were used to detect the effect of antimicrobial peptides on biofilm formation of SS2.XTT method was used to detect the effect of antimicrobial peptides on the biofilm metabolic activity of SS2.Phenol sulfuric acid method was used to detect the effect of antimicrobial peptides on the extracellular polysaccharide content of SS2 biofilm.HE staining was used to observe the effect of T-La(FS) on the pathological changes of zebrafish brain tissue.The effects of antimicrobial peptides on the biofilm related genes of SS2 and the transcription levels of inflammatory cytokines genes in zebrafish were analyzed by Real-time PCR.The results showed that SS2 had good biofilm formation ability.The MBIC of T-La(S),RGD-T-La(S),T-La(FS) and RGD-T-La(FS) on the biofilm of SS2 were 31.3,15.6,7.8 and 15.6 μg/mL,respectively.MBEC were 62.6,31.2,15.6 and 31.2 μg/mL,respectively.The results of crystal violet staining showed that the antibacterial peptides had inhibitory effect on the biofilm formation of SS2.The results of SEM showed that the number of bacteria and the morphology of biofilm of SS2 were significantly changed by antimicrobial peptides,and the extracellular matrix was greatly reduced.The results of XTT showed that antimicrobial peptides could significantly reduce the metabolic activity of the biofilm of SS2.The results of phenol sulfuric acid method showed that antimicrobial peptides could effectively inhibit the synthesis of extracellular polysaccharide from the biofilm of SS2.The results of Real-time PCR showed that the antibacterial peptide reduced the transcription level of biofilm gene of SS2.After treatment with T-La(FS),the transcription levels of TLR2,MyD88 and pro-inflammatory cytokine genes were significantly or extremely significantly decreased (P<0.05;P<0.01),while the transcription levels of anti-inflammatory cytokine genes were significantly or extremely significantly increased (P<0.05;P<0.01).Antimicrobial peptides inhibited the biofilm formation of SS2 mainly by affecting the transcription level of biofilm related genes and blocking the synthesis and secretion of extracellular polysaccharides.T-La (FS) might inhibit the release of inflammatory cytokines and alleviate the inflammatory response of meningitis by inhibiting the expression of TLR2 and MyD88 molecules in TLR2 signaling pathway.

Key words: antimicrobial peptide Temprine-La(FS); Streptococcus suis type 2; biofilm; zebrafish; TLR2; MyD88
