Preliminary Classification of Novel Hemorrhagic Fever-Causing Viruses Using Sequence-Based PAirwise Sequence...

Area of Science:

• Virology
• Bioinformatics
• Genomics

Background:

• Genome sequence data is increasingly used for virus classification.
• Traditional phylogenetic analysis for taxonomic placement is complex and requires expert knowledge.
• Novel methods are needed to simplify virus classification.

Purpose of the Study:

• To describe the application of the Pairwise Sequence Comparison (PASC) tool for preliminary classification of novel viruses.
• To demonstrate PASC as an accessible method for non-taxonomists.
• To highlight PASC's utility in classifying viral hemorrhagic fever viruses.

Main Methods:

• Utilizing the Pairwise Sequence Comparison (PASC) tool, an open-access resource from the US National Center for Biotechnology Information.
• Analyzing coding-complete viral genome sequences.
• Comparing PASC results with traditional phylogenetic analyses.

Main Results:

• PASC provides a method for virus classification based solely on genome sequence data.
• PASC results frequently align with those obtained from phylogenetic analyses.
• The PASC tool is computationally inexpensive and user-friendly for non-specialists.

Conclusions:

• Pairwise Sequence Comparison (PASC) is a viable and accessible method for the preliminary classification of novel viruses.
• PASC simplifies the taxonomic placement of viruses, particularly useful for emerging threats like viral hemorrhagic fever agents.
• This approach democratizes virus classification, enabling broader scientific participation.
