a novel genetic marker for the rapid detection of bacteroides fragilis in recreational water as a human-specific faecal indicator.bacteroides spp. has gained substantial interest among the suggested potential candidates for alternative faecal indicators for untreated recreational waters by the us epa. interest in bacteroides as a faecal indicator is based upon the relative abundance of selected members of the bacteroides genus in the human colon and human faeces. in this study, we developed a real-time pcr detection system based on gyrase b subunit genes (gyrb) specific to bacteroides fragilis. the gryb-based method was co ...201121942191
