K5 Prevents Enterohaemorrhagic O157:H7 Infection in Mice through the Modulation of the Gut Microbiota.

Enterohemorrhagic (EHEC) serotype O157:H7 is a commonly encountered foodborne pathogen that can cause hemorrhagic enteritis and lead to hemolytic uremic syndrome (HUS) in severe cases. is a beneficial bacterium that naturally exists in the human gut and plays a vital role in maintaining a healthy balance in the gut microbiota. This study investigated the protective effects of K5 in a mouse model of EHEC O157:H7 infection.

E3 Combined with E4 Improves LPS-Induced Intestinal Injury by Inhibiting the TLR4/NF-κB and MAPK Signaling Pathways .

Changes in the functions of the intestinal barrier occur in parallel with the development of sepsis. The protection by strains (BB, BL, BB12, and BLBB) was evaluated in mice injected with lipopolysaccharide (LPS). The results revealed an increase in the ratio of ileal villus length to crypt depth in the BLBB group compared with that in the LPS group, as were the number of IgA plasma, CD4/CD8 T, and dendritic cells.

Analysis of the complete genome sequence of Lactobacillus delbrueckii ssp. bulgaricus with post-acidification capacity and its influence on yogurt in storage.

In recent years, yogurt has been one of the most popular fermented dairy products and is sold worldwide. In this study, pH and titrated acid changes of 4 strains of Lactobacillus delbrueckii ssp. bulgaricus fermented milk during storage were detected.

Human milk and infant formula modulate the intestinal microbiota and immune systems of human microbiota-associated mice.

Many infants on an exclusive breastfeeding regimen are often fed inadequate amounts, and this creates an imbalance between the overall effects of breast milk and commercial infant formulas. We comparatively analyzed the impact of human milk and two infant formulas in modulating the intestinal microbiota and the immune systems of mice colonized by healthy infant feces. The results showed that compared to infant formula, human milk decreased the levels of alanine transaminase, alkaline phosphatase, and total protein.
