Quantitative CrAssphage PCR Assays for Human Fecal Pollution Measurement

Quantitative PCR for genetic markers of human fecal pollution.

Assessment of health risk and fecal bacterial loads associated with human fecal pollution requires reliable host-specific analytical methods and a rapid quantification approach. We report the development of quantitative PCR assays for quantification of two recently described human-specific genetic markers targeting Bacteroidales-like cell surface-associated genes. Each assay exhibited a range o...

Title : Quantitative PCR for genetic markers of human fecal pollution

Performance assessment PCR-based assays targeting bacteroidales genetic markers of bovine fecal pollution.

There are numerous PCR-based assays available to characterize bovine fecal pollution in ambient waters. The determination of which approaches are most suitable for field applications can be difficult because each assay targets a different gene, in many cases from different microorganisms, leading to variation in assay performance. We describe a performance evaluation of seven end-point PCR and ...

Quantitative PCR for detection and enumeration of genetic markers of bovine fecal pollution.

Accurate assessment of health risks associated with bovine (cattle) fecal pollution requires a reliable host-specific genetic marker and a rapid quantification method. We report the development of quantitative PCR assays for the detection of two recently described bovine feces-specific genetic markers and a method for the enumeration of these markers using a Markov chain Monte Carlo approach. B...

Validation of Quantitative PCR Assays

can assess the safety of biotechnology products. Q-PCR precisely quantifies the amount of the nucleic acid target sequence in DNA or RNA extracted from a variety of samples including animal tissues, final products, cell banks, chromatography eluates, and bulk harvest material. During amplification with target-specific oligonucleotide primers, a fluorogenic oligonucleotide probe — with both repo...
