Objectives: The aim of the study was to examine the effects of a follow-on formula containing Lactobacillus fermentum CECT5716 (L. fermentum) on the incidence of infections in infants between the ages of 6 and 12 months.
Patients And Methods: A randomized double-blinded controlled study including infants at the age of 6 months was conducted. Infants were assigned randomly to either follow-on formula supplemented with L. fermentum plus galactooligosaccharide (experimental group, EG), or the same formula supplemented with only galactooligosaccharide (control group, CG). The main outcome was the incidence of infections for the 6-month duration of the study.
Results: The EG showed a significant 46% reduction in the incidence rate (IR) of gastrointestinal infections (EG: 0.196 ± 0.51, CG: 0.363 ± 0.53, IR ratio 0.54, 95% confidence interval [CI] 0.307-0.950, P = 0.032), 27% reduction in the incidence of upper respiratory tract infections (EG: 0.969 ± 0.96, CG: 1.330 ± 1.23, IR ratio 0.729, 95% CI 0.46-1.38, P = 0.026), and 30% reduction in the total number of infections (EG: 1.464 ± 1.15, CG: 2.077 ± 1.59, IR ratio 0.70, 95% CI 0.46-1.38, P = 0.003), at the end of the study period compared with CG.
Conclusions: Administration of a follow-on formula with L. fermentum CECT5716 may be useful for the prevention of community-acquired gastrointestinal and upper respiratory infections.

Different infant formulas can activate toll-like receptor 9 in vitro and inhibit interleukin 6 in human primary intestinal epithelial cells.

Purpose: Necrotizing enterocolitis (NEC) is the most severe gastrointestinal disease in preterm infants caused by an exaggerated intestinal epithelial immune activation. Several studies show that modulation of toll-like receptor 9 (TLR9) activity may have positive effects on preventing intestinal inflammatory mechanisms ultimately resulting in NEC development. In this study, the effect of various infant formulas (IF) and the probiotic strain Limosilactobacillus fermentum CECT5716 on TLR9 activation were analyzed in vitro.

Over the past decades, the prevalence of allergic diseases noticeably increased in industrialized countries. The Th2 immune response plays a central role in these pathologies and its modulation using pro-/postbiotics constitutes a promising approach to prevent or alleviate disease symptoms. The aim of this in vitro study, was to investigate the ability of human milk-derived Bifidobacterium breve DSM 32583 (Bb) and Limosilactobacillus fermentum CECT5716 (Lf), to modulate the Th2 induced responses.

Imidazole-chalcone compounds are recognised for their broad-spectrum antimicrobial properties. Probiotic-friendly, selective new-generation antimicrobials prove to be more efficient in combating gastrointestinal system pathogens. The aim of this study is to identify imidazole-chalcone derivatives that probiotics tolerate and evaluate their in vitro synergistic antimicrobial effects on pathogens.

Increasing evidence suggests the beneficial immunomodulatory effects of probiotics can reduce inflammation in systemic lupus erythematosus (SLE). However, there is no summary of the existing evidence available. This study aims to investigate the therapeutic effects of probiotics on SLE in a lupus mouse model by examining various markers, including inflammatory cytokines, Treg cells, disease activity, and gut microbiota.

Background: Early life nutrition is crucial for the development of the gut microbiota that, in turn, plays an essential role in the maturation of the immune system and the prevention of infections.
Objectives: The aim of this study was to investigate whether feeding synbiotic infants and follow-on formulas during the first year of life reduces the incidence rate (IR) of infectious diarrhea compared with standard formulas. Secondary endpoints included the IR of other infectious diseases as well as fecal milieu parameters.
