Viral Metagenomic Sequencing & Analysis (Virome Profiling)

iral Metagenomic Sequencing (Virome Profiling) leverages Next-Generation Sequencing (NGS) to directly capture, map, and analyze the total viral genetic material—comprising both DNA and RNA viruses—present in a complex sample. Unlike bacteria, viruses lack a universally conserved marker gene (such as 16S rRNA); hence, unbiased Shotgun RNA/DNA sequencing workflows are utilized. This approach enables the comprehensive discovery of known human pathogens as well as novel, mutated, or rare viral agents without prior culturing or targeted primers.

Key Features & Advantages

1. Culture & Primer-Independent Discovery: Detects all known and novel viral genomes simultaneously within clinical or environmental samples without targeted amplification bias.
2. Comprehensive DNA & RNA Coverage: Tailored library preparation strategies covering single/double-stranded DNA viruses as well as enveloped/non-enveloped RNA viruses.
3. Advanced Bioinformatic Dehosting: Computational depletion of host genomic DNA and RNA to maximize viral read counts and enhance overall diagnostic resolution.
4. Emerging Pathogen Identification: Unmatched potential for identifying novel mutant strains, emerging zoonotic spillover events, and diagnostic-evading viruses.

Viral Metagenomics vs. Targeted Multiplex PCR Panels

Key Applications

1. Idiopathic & Undiagnosed Infectious Diseases: Identifying etiologic agents in unresolved cases of encephalitis, hemorrhagic fevers, or severe respiratory illness.
2. Public Health & Zoonotic Surveillance: Monitoring animal-to-human spillover events and mapping viral diversity for pandemic preparedness.
3. Transplantation & Immunocompromised Care: Profiling opportunistic latent and active viral loads (e.g., CMV, EBV, BK virus) in transplant recipients.
4. Wastewater & Environmental Virology: Tracking viral population dynamics and community transmission trends through municipal wastewater epidemiology.
5. 
   

The Nucleus Genetics Advantage: Combining optimized physical host depletion protocols, de novo viral assembly pipelines, and curated databases (NCBI RefSeq, GISAID), we identify ultra-low abundance viral particles and deliver actionable virome intelligence.
