The effect of oral administration of a polysaccharide (KGF-C), isolated from the kefir grain, on delayed-type hypersensitivity (DTH) induced by picryl chloride and on the growth of solid tumor was examined in mice. KGF-C caused an increase in DTH response in intact mice and also tumor-bearing mice. The growth of tumor inoculated after the DTH test was markedly inhibited in the groups with high ...

We report here the genome sequences of three novel bacterial species strains-Bacillus kefirresidentii Opo, Rothia kefirresidentii KRP, and Streptococcus kefirresidentii YK-isolated from kefir grains collected in Germany. The draft genomes of these isolates were remarkably dissimilar (average nucleotide identities, 77.80%, 89.01%, and 92.10%, respectively) to those of the previously sequenced st...

Daily administration of the probiotic kefir given in combination with a staggered and tapered antibiotic withdrawal regimen may resolve recurrent Clostridium difficile infection as effectively as fecal microbiota transplantation.

Implication for health policy/practice/research/medical education: Originally different kefir grains may contain various microbial complexes. The beneficial effects of probiotic microorganisms vary from strain to strain and condition to condition. Knowing their microbial characterizations is needed for the safety confirmation.

Kefiran, the polysaccharide produced by microorganisms present in kefir grains, is a water-soluble branched glucogalactan containing equal amounts of D-glucose and D-galactose. In this study, the effect of kefiran on the biological activity of Bacillus cereus strain B10502 extracellular factors was assessed by using cultured human enterocytes (Caco-2 cells) and human erythrocytes. In the presen...

Whole-genome sequencing was performed for Lactobacillus parakefiri JCM 8573T to confirm its hitherto controversial taxonomic position. Here, we report its first reliable reference genome. Genome-wide metrics, such as average nucleotide identity and digital DNA-DNA hybridization, and phylogenomic analysis based on multiple genes supported its taxonomic status as a distinct species in the genus L...

The objective of this study was to evaluate the chemical, sensory properties and stability of a functional soy product with soy fiber and fermented with probiotic kefir culture. The product was characterized by the chemical composition, color and sensory analysis. The stability of the product was evaluated by pH, acidity, viscosity, firmness, syneresis measurements and cells counts. The functio...

The control of the immune system pigs after weaning is important in pig farming because productivity depends on survival post-weaned pigs. Previously, antibiotics would have been administered case infectious diseases to increase rate pigs, but now, use strictly restricted order prevent other problems such as occurrence antibiotic-resistant pathogens. In this study, effect fermented kefir a func...
