Journal ArticleDOI
Lactobacillus acidophilus LA 1 binds to cultured human intestinal cell lines and inhibits cell attachment and cell invasion by enterovirulent bacteria.
TL;DR: Investigation of the inhibitory effect of LA 1 organisms against Caco-2 cell adhesion and cell invasion by a large variety of diarrhoeagenic bacteria found incubation before and together with enterovirulent E coli were more effective than incubation after infection by E coli.
Journal ArticleDOI
Bifidobacterium strains from resident infant human gastrointestinal microflora exert antimicrobial activity
Vanessa Liévin,I Peiffer,Sylvie Hudault,Florence Rochat,Dominique Brassart,Jean-Richard Neeser,Alain L. Servin +6 more
TL;DR: Several bifidobacterium strains from resident infant human gastrointestinalmicroflora exert antimicrobial activity, suggesting that they could participate in the “barrier effect” produced by the indigenous microflora.
Journal ArticleDOI
Adhesion of human bifidobacterial strains to cultured human intestinal epithelial cells and inhibition of enteropathogen-cell interactions
TL;DR: In this paper, 13 human bifidobacterial strains were tested for their ability to adhere to human enterocyte-like Caco-2 cells in culture, and the adhesion occurs to the apical brush border of the enterocytic Caco2 cells and to the mucus secreted by the human mucus-secreting HT29-MTX cell line.
Journal ArticleDOI
Identification and characterization of the eps (Exopolysaccharide) gene cluster from Streptococcus thermophilus Sfi6.
TL;DR: EPS expression in the non-EPS-producing heterologous host, Lactococcus lactis MG1363, showed that within the 15.25-kb region, a region with a size of 14.52 kb encoding the 13 genes epsA to epsM was capable of directing EPS synthesis and secretion in this host.
Journal ArticleDOI
The human Lactobacillus acidophilus strain LA1 secretes a nonbacteriocin antibacterial substance(s) active in vitro and in vivo
Marie-Françoise Bernet-Camard,Vanessa Liévin,Dominique Brassart,Jean-Richard Neeser,Alain L. Servin,Sylvie Hudault +5 more
TL;DR: The spent culture supernatant of strain LA1 (LA1-SCS) contained antibacterial components active against S. typhimurium infecting the cultured human intestinal Caco-2 cells, and the LA1- SCS antibacterial activity was insensitive to proteases and independent of lactic acid production.
