THE EFFECT OF N-ACETYL-L-CYSTEINE ON BIOFILM OF VIBRIO CHOLERAE

Aim. To study the effect of N-acetyl-L-cysteine on biofilm of V. cholerae of different sero-groups isolated from various sources and with different epidemiological significance (the presence/ absence of the ctx AB genes and tcpA).

Zusammenfassung:Aim. To study the effect of N-acetyl-L-cysteine on biofilm of V. cholerae of different sero-groups isolated from various sources and with different epidemiological significance (the presence/ absence of the ctx AB genes and tcpA). Materials and methods. Bacterial eiiltiire of Vibrio cholerae El Tor O1 and O139 serogroups were grown as biolms. We have estimated the influence of the drug N-acetyl-L-cysteine at a concentration of 0.5 - 4 mg/ml on the formation, of the formed biofilm and in planktonic form. Results. Discovered antibacterial activity of N-acetyl-L-cysteine. Noted that it was influenced as in the formation, of the already formed biofilm and the planktonic form, the representatives of the Vibrio cholerae El Tor O1 and O139 serogroups in concentrations of 2 - 4 mg/ml, showing an antibacterial effect regardless of the presence/absence of genes ctx and tcpA AB. Conclusion. Identified the antibacterial action of the drug N-acetyl-L-cysteine against biofilm of V. cholerae indicates the desirability of considering the possibility of using drug therapy in cases variety of diseases caused by causative agents II - IV groups pathogenicity.
