Design and evaluation of Bacteroides DNA probes for the specific detection of human fecal pollution

Abstract excerpt

Because Bacteroides spp. are obligate anaerobes that dominate the human fecal flora, and because some species may live only in the human intestine, these bacteria might be useful to distinguish human from nonhuman sources of fecal pollution. To test this hypothesis, PCR primers specific for 16S rRNA gene sequences of Bacteroides distasonis, B. thetaiotaomicron, and B. vulgatus were designed. Hybridization with...
