Comparison of the Host Specificities of Two Bacteroidales Quantitative PCR Assays Used for Tracking Human Fecal Contamination

摘要

The sewage-associated real-time quantitative PCR (qPCR) assays BacHum and HF183 SYBR were compared for specificity against local fecal sources. Both assays were equally sensitive to sewage, but BacHum showed substantially more false-positive results for cat, dog, gull, and raccoon feces.
