Reductions in pathogen counts by L. amylovous culture supernatants. Six different swine intestinal pathogens were grown in TSB medium in the presence of the filter-sterilized supernatants of the L. amylovorus strains, and the reductions in pathogen counts, expressed as log CFU values, were estimated from the area reduction percentages (ARPs) of the pathogen growth curves by linear regression. The average pH values of the supernatants are shown above the histograms. The results are the means and standard deviations of three independent experiments, each performed with fresh culture supernatants with three technical replicates.
