Effects of Colistin and Bacteriocins Combinations on the In Vitro Growth of Escherichia coli Strains from Swine Origin

Abstract

Escherichia coli strains from swine origin, either susceptible or resistant to colistin, were grown under planktonic and biofilm cultures. After which, they were treated with antibacterial agents including nisin and enterocin DD14 bacteriocins, colistin and their combinations. Importantly, the combination of colistin, enterocin DD14 and nisin eradicated the planktonic and biofilm cultures of E. coli CIP54127 and the E. coli strains with colistin-resistance phenotype such as E. coli 184 (mcr-1 +) and E. coli 289 (mcr-1 -), suggesting therefore that bacteriocins from lactic acid bacteria could be used as agents with antibiotic augmentation capability.

Keywords: Bacteriocins; Biofilms; Colistin; E. coli; Enterocin DD14; Nisin; Planktonic.
