Conventional RT-PCR for Yellow Fever Virus.

Area of Science:

• Virology
• Molecular Biology
• Infectious Diseases

Background:

• Yellow fever virus (YFV) belongs to the Orthoflavivirus genus within the Flaviviridae family.
• YFV possesses a positive-sense RNA genome encoding a single polyprotein of 3411 amino acids.
• Various molecular assays exist for YFV RNA detection, varying in sensitivity and specificity.

Purpose of the Study:

• To present conventional Reverse Transcription Polymerase Chain Reaction (RT-PCR) protocols for Yellow Fever Virus (YFV) molecular diagnostics.
• To highlight the utility of molecular methods for early YFV detection.

Main Methods:

• Review and presentation of established Reverse Transcription Polymerase Chain Reaction (RT-PCR) protocols.
• Focus on methods for detecting Yellow Fever Virus (YFV) RNA.

Main Results:

• Reverse Transcription Polymerase Chain Reaction (RT-PCR) assays are the predominant methods for current YFV molecular diagnostics.
• Molecular diagnostic methods offer rapid, sensitive, and highly specific alternatives to serological assays.
• These methods are valuable for early diagnosis during the viremic phase and for analyzing tissues in fatal cases.

Conclusions:

• Conventional RT-PCR protocols provide effective means for Yellow Fever Virus (YFV) molecular diagnostics.
• Molecular detection of YFV RNA is essential for timely and accurate diagnosis.
• The presented protocols contribute to the available toolkit for YFV detection.
