It has been widely
shown that strains of L. reuteri exhibit properties of an effective
probiotic organism: adhesive properties [35], survival conditions
likely to be encountered throughout the GIT of pig [34]
and secretion of bacteriocin-like products [43]. L. plantarum
is known to produce antimicrobial substances, e.g., plantaricin,
that are active against certain pathogens [7]. In our experimental
conditions, no cell growth inhibition was observed for B. hyodysenteriacae.
The antimicrobial activity was also shown by
using lactobacillus cells treated with simulated gastric and intestinal
fluids, indicating that these strains could also be active
in the GIT of pigs.
