| Abstract |
AIMS:To select adhesive strains among strains of Lactobacillus and to apply them to inhibit adhesion of food-borne pathogens. METHODS AND RESULTS:Twelve Lactobacillus strains (10 from intestine) were examined for adhesion using Caco-2 cell cultures. The two most adhesive strains, Lactobacillus crispatus JCM 8779 and Lact. reuteri JCM 1081, were used to test antiadhesion activity against enterotoxigenic Escherichia coli, Salmonella typhimurium and Enterococcus faecalis strains. Adhesion of the pathogens was inhibited by both Lactobacillus strains. Adhesion of Ent. faecalis was especially strongly inhibited by JCM 8779. Although antimicrobial activity was not detected in the culture supernatant fluid by agar well diffusion assay, the supernatant fluid obtained from the harvested JCM 8779 cell suspension showed bactericidal activity against Ent. faecalis. CONCLUSION:The strong antiadhesion activity of JCM 8779 against Ent. faecalis appears to be due to the combined effect of both bactericidal activity and competition for attachment site. SIGNIFICANCE AND IMPACT OF THE STUDY:This is the first report that Lact. crispatus produces a bactericidal substance. |
