This study aims to investigate the effect of Bifidobacterium adolescentis against noroviruses (NoVs). Murine norovirus-1 (MNV-1) used as a surrogate was detected by plaque assay and RT-qPCR. Human NoV virus like particles (VLPs) were detected by cell-binding assay. It was shown that the presence of B. adolescentis could inhibit the multiplication of MNV-1 on RAW 264.7 cells within 48 h of co-in...

background and objectives: dental caries, caused by oral microbial flora, is considered as one of the most common infectious diseases in human. the aim of this study was to determine the effect of short-term consumption of probiotic yogurt containing bifidobacterium lactis on salivary streptococcus mutans and lactobacilli in students with initial stages of dental caries. materials and methods: ...

Bifidobacteria are members of the human gut microbiota, being numerically dominant in the colon of infants, while also being prevalent in the large intestine of adults. In this study, we determined and analyzed the pan-genome of Bifidobacterium adolescentis, which is one of many bacteria found in the human adult gut microbiota. In silico analysis of the genome sequences of eighteen B. adolescen...

Probiotic microorganisms are incorporated into a wide variety of foods, supplements, and pharmaceuticals to promote human health and wellness. However, maintaining bacterial cell viability during storage and gastrointestinal transit remains a challenge. Encapsulation of bifidobacteria within food-grade hydrogel particles potentially mitigates their sensitivity to environmental stresses. In this...

MICs of tetracyclines were determined for 86 human Bifidobacterium isolates and three environmental strains. The tet(O) gene was found to be absent in these isolates. tet(W) and tet(M) were found in 26 and 7%, respectively, of the Bifidobacterium isolates, and one isolate contained both genes. Chromosomal DNA hybridization showed that there was one chromosomal copy of tet(W) and/or tet(M).

We report the genome sequence of Bifidobacterium animalis subspecies lactis BL3, which has preventive properties on acute colitis and colon cancer. The genome of BL3, which was isolated from Korean faeces, consisted of a 1 944 323 bp size single chromosome, and its G+C content was 60.5%. Genome comparison against the closest Bifidobacterium animalis strain revealed that BL3 had particularly dif...

The complete genome sequence of Bifidobacterium pseudolongum PV8-2, isolated from feces of an anemic Kenyan infant, was determined using single-molecule real-time (SMRT) technology. The genome consists of a 2-Mbp chromosome and a 4-kb plasmid.

Phospholipid composition of 10 Bifidobacterium strains of human intestinal origin and of 9 Lactobacillus strains was determined by quantitative two-dimensional thin-layer chromatography. Phospholipids of three Bifidobacterium strains from honey bees and of two strains from bovine rumen liquor were qualitatively investigated. Diphosphatidylglycerol and phosphatidylglycerol were present in strain...
