tuf Gene Sequence Variation in Bifidobacterium longum subsp. infantis Detected in the Fecal Microbiota of Chinese Infants.

ABSTRACT: Members of the bacterial genus Bifidobacterium generally dominate the fecal microbiota of infants. The species Bifidobacterium longum is prevalent, but the B. longum subsp. longum and B. longum subsp. infantis strains that are known to colonize the infant bowel are not usually differentiated in microbiota investigations. These subspecies differ in their capacities to metabolize human milk oligosaccharides (HMO) and may have different ecological and symbiotic roles in humans. Quantitative PCR provides a quick analytical method by which to accurately ascertain the abundances of target species in microbiotas and microcosms. However, amplification targets in DNA extracted from samples need to be dependably differential. We evaluated the tuf gene
