Abstract
Inhibitory effect of various lactobacilli against pathogenic strains ofE. coli in model system Caco2 cells was determined by enumerating the number of adheringE. coli after pre-incubation (exclusion), post-incubation (displacement) or co-incubation (competition) with lactobacilli. PorcineE. coli strain F107 (F18ab, Stx2v) in the competition assay with porcine lactobacillus strain P10 gave bacterial counts 7.25 (log CFU per well); in the exclusion test it was only 7.05 while in displacement test it reached 7.29. The lowestE. coli counts adhering to Caco-2 cells were in exclusion assay (pre-incubation,Lactobacillus inoculated as the first). Pre-treatment ofE. coli with our lactobacilli strains reduced the cultivableE. coli numbers.
