Methods to detect infectious human enteric viruses in environmental water samples

Area of Science:

• Environmental virology
• Water quality analysis

Background:

• Molecular methods like PCR and qPCR are sensitive for virus detection in water but don't confirm infectivity.
• Traditional cell culture assays are the gold standard for infectivity but are laborious, costly, and not universally applicable.
• Limitations exist for detecting infectious viruses, impacting public health risk assessment.

Purpose of the Study:

• To review and critically evaluate novel methods for detecting infectious viruses in environmental water samples.
• To address the limitations of traditional PCR and cell culture assays.
• To explore techniques that correlate viral detection with infectivity and public health significance.

Main Methods:

• Review of recent approaches including integrated cell culture-PCR.
• Evaluation of methods assessing viral genome and capsid integrity.
• Discussion of techniques measuring oxidative damage on viral proteins.
• Consideration of rapid detection methods like fluorescence microscopy and flow cytometry.

Main Results:

• New integrated and integrity-based methods show promise in overcoming traditional assay limitations.
• Rapid detection techniques offer faster assessment of virus infectivity.
• These approaches aim to bridge the gap between viral detection and actual health risk.

Conclusions:

• Novel strategies are emerging to accurately assess infectious virus levels in water.
• These advancements are crucial for reliable public health risk assessment in environmental virology.
• Further research and validation of these methods are needed.
