Hypothesis

Random amplification of viral nucleic acids isolated from human plasma might provide a powerful new method to detect and identify novel and recombined viruses.

Conclusion

The study suggests that random multiplex (RT)-PCR can detect and identify multiple viruses in human plasma without using virus-specific reagents.

Supporting Evidence

  • The method detected Adenovirus Type 17, Coxsackievirus A7, and Respiratory Syncytial Virus B in human plasma.
  • The random multiplex PCR method is sensitive to ~1000 genome equivalents/ml.
  • The study demonstrated the ability to identify viruses without using virus-specific reagents.

Takeaway

Scientists found a new way to quickly find viruses in blood by using a special test that doesn't need to know the virus's exact makeup first.

Methodology

The study used a novel PCR method called Random Multiplex (RT)-PCR to amplify viral nucleic acids from human plasma after filtration and nuclease treatment.

Limitations

The method's sensitivity is lower than virus-specific PCR, and there may be background amplification leading to false positives.
