Exopolysaccharides From Lactobacillus delbrueckii subsp. bulgaricus OLL1073R-1 Enhance Macrophage Bactericidal Activity Through IL-12-Dependent Macrophage-NK Cell Crosstalk. [PDF]

Microbiol Immunol
ABSTRACT Exopolysaccharides (EPS) produced by Lactobacillus delbrueckii subsp. bulgaricus OLL1073R‐1 have been reported to exert immunomodulatory effects, primarily in antiviral responses; however, their role in antibacterial host defense remains unclear. Here, we investigated whether EPS enhance macrophage‐mediated killing of Streptococcus pyogenes, a
