Efficiently sequence key microbial targets

Using targeted NGS to reduce cost and accelerate analysis

What is targeted microbial sequencing?

Within complex samples, targeted microbial sequencing is an efficient way to resolve microbial DNA/RNA sequences from non-microbial DNA/RNA while allowing researchers to efficiently identify and characterize microbes of interest. With the power of next-generation sequencing (NGS), techniques such as amplicon sequencing and hybridization (hybrid) capture enrichment are effective methods that can reduce the cost of sequencing and streamline data analysis.

Amplicon vs hybrid capture enrichment

Amplicon sequencing and hybrid capture are popular methods to perform targeted sequencing. Each approach has different considerations based on the goals of the study. Amplicon sequencing is a highly targeted method to analyze genetic variation in specific genomic regions. This method uses oligonucleotide primers designed to target and amplify small genomes or specific regions of interest, followed by NGS. Hybrid capture is a method that uses biotinylated probes specific to a genomic region of interest. Once bound, these hybridized genomic fragments can be captured by streptavidin for amplification and sequencing.

	Amplicon sequencing	Hybrid capture
Targets	Smaller number of targets	Larger number of targets
Example use cases	Single virus variant tracking Tuberculosis drug resistance	Broad pathogen surveillance Antimicrobial resistance surveillance
Workflow	Simpler and faster turnaround times	More complex and time-consuming
