Immune modulation of blood leukocytes in humans by lactic acid bacteria: criteria for strain selection.
Reads0

TLDR
Bacterial adhesion to enterocytes, fecal colonization, or both seem to be valuable selection criteria for immunomodulation, and antiinfective mechanisms of defense can be enhanced after ingestion of specific lactic acid bacteria strains.About:

Journal ArticleDOI
Probiotic bacteria: safety, functional and technological properties
TL;DR: In this article, several aspects, including safety, functional and technological characteristics, have to be taken into consideration in the selection process of probiotic micro-organisms, including origin (healthy human GI tract), non-pathogenicity and antibiotic resistance characteristics.
Journal ArticleDOI
Antagonistic activities of lactobacilli and bifidobacteria against microbial pathogens
TL;DR: There is increasing evidence that lactobacilli and bifidobacteria, which inhabit the gastrointestinal microbiota, develop antimicrobial activities that participate in the host's gastrointestinal system of defence.
Journal ArticleDOI
Probiotic Mechanisms of Action
Miriam Bermudez-Brito,Julio Plaza-Díaz,Sergio Muñoz-Quezada,Carolina Gomez-Llorente,Angel Gil +4 more
TL;DR: Probiotics modes of action focusing on how gut microbes influence the host are explored, with a clear understanding of these mechanisms allowing for appropriate probiotic strain selection for specific applications and may uncover novel probiotic functions.
Journal ArticleDOI
Taxonomy and important features of probiotic microorganisms in food and nutrition
TL;DR: Molecular typing methods such as pulsed-field gel electrophoresis, repetitive polymerase chain reaction, and restriction fragment length polymorphism are extremely valuable for specific characterization and detection of such strains selected for application as probiotics.
Journal ArticleDOI
Functional cultures and health benefits
TL;DR: A number of health benefits have been claimed for probiotic bacteria such as Lactobacillus acidophilus, Bifidobacterium spp.

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
Modulation of a specific humoral immune response and changes in intestinal flora mediated through fermented milk intake
TL;DR: Results indicate that lactic acid bacteria which can persist in the gastrointestinal tract can act as adjuvants to the humoral immune response.

CR3 (CD11b, CD18): a phagocyte and NK cell membrane receptor with multiple ligand specificities and functions
Gordon D. Ross,V. Větvička +1 more
TL;DR: The C3 receptor CR3 is expressed on phagocytie cells, minor subsets of B and T eells.
Journal ArticleDOI
Protein-mediated adhesion of Lactobacillus acidophilus BG2FO4 on human enterocyte and mucus-secreting cell lines in culture.

TL;DR: In this paper, the adhesion of Lactobacillus acidophilus BG2FO4, a human stool isolate, to two human enterocytelike cell lines (Caco-2 and HT-29) and to the mucus secreted by a subpopulation of mucussecreting HT29-MTX cells was investigated.
