The influence of gender and obesity on the abundance of human colonic Feacalibacterium prausnitzii is currently unclear. We collected fecal samples from 54 obese and 54 sex- and age-matched normal-weight Chinese adults and quantified the fecal F. prausnitzii as percentage of 16S rRNA gene copies of F. prausnitzii accounting to that of total gut bacteria with quantitative PCR. The fecal F. prausnitzii...
DNA restriction fragment polymorphism technologies such as amplified ribosomal DNA restriction analysis (ARDRA) and terminal restriction fragment length polymorphism (T-RFLP) have been widely used in investigating microbial community structures. However, these methods are limited due to either the low resolution or sensitivity. In this study, a fluorophore-ribosomal DNA restriction typing (f-DRT)...
