Detecting novel viral strains with One Codex and Twist Viral Research Panels
Sequencing viral genomes from mixed microbial community samples is challenging due to the relatively low quantity of viral reads compared to host and/or background. One Codex and Twist Bioscience have co-developed targeted enrichment-based sequencing and analysis kits for recovery of whole viral genomes from high-background samples1. This semi-targeted approach enables enrichment of known viruses while still capturing novel viruses.
The Twist Viral Research panels bundled with One Codex analysis are available in two versions. The Twist Respiratory Viral Research panel covers 29 human and respiratory viral pathogens. The larger Twist Comprehensive Viral Research Panel covers 3,153 viral pathogens known to infect both humans and animals2. Both versions have been applied across public health, medicine, academia and industry in diverse use cases, such as evaluating wastewater viromes3, characterization of emerging pathogens4, discerning the infectious agent in an outbreak5, evaluating co-infections6, and novel strain detection6, 7.
Viral consensus genomes are often the starting point for downstream analyses such as in lineage/strain identification, phylogenetic analysis, genomic surveillance and outbreak investigation. To streamline and standardize these analyses, we have added automated viral consensus genome generation to the analysis of all our viral research panels (Figure 1). Our approach to consensus genome generation is based on published best practices and is optimized for data generated using both Twist viral enrichment panels. To find out more about the bioinformatics methods, see our documentation. Output consensus FASTA files can now be found via links provided in the PDF report (Figure 1, sample report).
