Effect of L. helveticus LH-2 and L. acidophilus La-5 CFSM on virulence gene expression of S. Typhimurium DT104 and S. Typhimurium oppA mutant. Expression ratios of hilA and ssrB genes of S. Typhimurium were normalized to the expression of the geometric average of regulator genes 16S rRNA, rpoD, gmk to obtain the fold-change and compared with those of the non-fermented media.
