Optimization of RT-PCR methods for enterovirus detection in groundwater

Area of Science:

• Environmental microbiology
• Virology
• Molecular biology

Background:

• Enteroviruses (EVs) are a significant public health concern, causing mild to severe illnesses and spreading through contaminated water.
• Accurate detection of EVs in water is essential for monitoring and preventing outbreaks.

Purpose of the Study:

• To establish and optimize a sensitive polymerase chain reaction (PCR) method for detecting enteroviruses (EVs) in water samples.
• To compare the sensitivity of real-time and conventional reverse transcription PCR (RT-PCR) for EV detection.

Main Methods:

• Developed and optimized PCR conditions using Coxsackievirus B5 (CV-B5) and Echovirus 30 (E-30).
• Compared conventional RT-PCR and real-time RT-PCR methods.
• Determined the detection limits for both PCR methods.

Main Results:

• Optimized PCR conditions and selected sensitive primer sets for EV detection.
• Quantified detection limits: conventional RT-PCR detected 10^5-10^6 copy/mL for CV-B5 and 10^6-10^7 copy/mL for E-30.
• The developed method demonstrated high sensitivity for EV detection in water.

Conclusions:

• The optimized PCR method provides a sensitive tool for detecting enteroviruses in water samples.
• This technique is expected to aid in investigating EV outbreaks linked to water contamination.
• Enhanced surveillance of waterborne EVs can improve public health protection.
