A September abstract in the Journal of Food Protection covers the effects of probiotics on Salmonella strains.

Enterococcus faecium and Enterococcus gallinarum strains were isolated from a commercial probiotic product and the effects of these strains on the growth of Salmonella enterica serovar Enteritidis strain IFO3313 were investigated.

Cell counts of Salmonella Enteritidis in mixed cultures with the probiotic product isolate of E. faecium were significantly lower than those in pure cultures. Longer time periods dramatically reduced the activity of Salmonella.

These results indicated that enterococcal strains exhibit inhibitory effects on the growth of Salmonella Enteritidis and these effects were due to both enterocin and nonenterocin factors.
