In vitro evaluation of Lactobacillus crispatus K313 and K243: High-adhesion activity and anti-inflammatory effect on Salmonella braenderup infected intestinal epithelial cell

Currently, there is an increasing interest in the use of probiotics as an alternative strategy to antimicrobial compounds. In this study, two high adhesive strains Lactobacillus crispatus K313 adhering to HT-29 cells as well as Lb. crispatus K243 adhering to collagen type IV were isolated from chicken intestines. SDS-PAGE analysis revealed the presence of the potential S-proteins SlpA and SlpB in Lb. crispatus K243 and K313. SlpA and SlpB, rich...
