Intraspecies Genomic Diversity and Long-Term Persistence of Bifidobacterium longum

Members of genus Bifidobacterium are Gram-positive bacteria, representing a large part of the human infant microbiota and moderately common in adults. However, our knowledge about their diversity, intraspecific phylogeny and long-term persistence in humans is still limited. Bifidobacterium longum is generally considered to be the most common and prevalent species in the intestinal microbiota. I...

Differentiation of Bifidobacterium longum subspecies longum and infantis by quantitative PCR using functional gene targets

BACKGROUND Members of the genus Bifidobacterium are abundant in the feces of babies during the exclusively-milk-diet period of life. Bifidobacterium longum is reported to be a common member of the infant fecal microbiota. However, B. longum is composed of three subspecies, two of which are represented in the bowel microbiota (B. longum subsp. longum; B. longum subsp. infantis). B. longum subspe...

Transposon Mutagenesis in Bifidobacterium breve: Construction and Characterization of a Tn5 Transposon Mutant Library for Bifidobacterium breve UCC2003

Bifidobacteria are claimed to contribute positively to human health through a range of beneficial or probiotic activities, including amelioration of gastrointestinal and metabolic disorders, and therefore this particular group of gastrointestinal commensals has enjoyed increasing industrial and scientific attention in recent years. However, the molecular mechanisms underlying these probiotic me...
