| Popis: | An alternative therapy to diarrhoeal episodes induced by E. coli is represented by probiotic strains (e.g Lactobacillus), which are able to maintain the gut micro-flora in optimal parameters. This work highlights the inhibitory potential of probiotics (L. plantarum ATCC 8014) over the enteropathogenic bacteria like E. coli ATCC 25922. For this study we co-incubated L. plantarum with E. coli in MRS broth at different concentrations (109, 108 CFU/mL – L. plantarum with 105, 104 CFU/mL – E. coli, 4 groups) for 24, 48 and 72h at 37oC. After co-incubation, E. coli colonies developed on Levine media were counted towards the control. E. coli colonies decreased after 48 and 72h of co-incubation with L. plantarum. Also, was noticed that L. plantarum (108 CFU/mL) completely inhibits E. coli (104 CFU/mL) after 72h of co-incubation. This work proves the inhibitory potential of probiotic strains (L. plantarum ATCC 8014) against enteropathogenic bacteria (E. coli ATCC 25922). |
