Dupleksowy cyfrowy test PCR do jednoczesnej kwantyfikacji Enterococcus spp. i ludzkiego markera HF183 związanego z kałem w wodzie

Overview

This manuscript describes a Duplex Digital PCR Assay designed to quantify both general and human-associated fecal contamination in recreational waters. The assay focuses on measuring Enterococcus spp. and the HF183 genetic markers, providing a comprehensive approach to water quality monitoring.

Key Study Components

Area of Science

• Environmental Microbiology
• Water Quality Assessment
• Genetic Marker Analysis

Background

• Recreational waters can be contaminated by fecal matter.
• Enterococcus spp. serves as a general fecal indicator.
• The HF183 marker is specifically associated with human fecal contamination.
• Current methods may involve biases and variability due to standard curves.

Purpose of Study

• To develop a method for simultaneous quantification of fecal indicators.
• To improve accuracy in assessing water quality.
• To eliminate the need for standard curves in quantification.

Methods Used

• Duplex Digital PCR assay development.
• Preparation of stock concentrations for primers and probes.
• Quantification of Enterococcus spp. and HF183 markers.
• Comparison with traditional qPCR methods.

Main Results

• Successful quantification of both fecal indicators in a single reaction.
• Reduction of bias and variability compared to qPCR.
• Demonstration of the assay's effectiveness in real-world applications.

Conclusions

• The Duplex Digital PCR assay is a reliable tool for water quality monitoring.
• It provides a more efficient method for assessing fecal contamination.
• This approach can enhance public health protection in recreational waters.
