Small genome sequencing (≤ 5 Mb) involves sequencing the entire genome of a bacterium, virus, or other microbe, and then comparing the sequence to a known reference. Sequencing small microbial genomes can be useful for food testing in public health, infectious disease surveillance, molecular epidemiology studies, and environmental metagenomics.

Unlike traditional approaches, small genome sequencing studies using next-generation sequencing (NGS) do not rely on labor-intensive cloning steps. NGS also enables biologists to sequence hundreds of organisms simultaneously via multiplexing. NGS can identify low-frequency variants, genomic rearrangements, and other genetic changes that might be missed or are too costly to identify using other methods. For small genomes, DNA libraries can be prepared, sequenced, and analyzed in as little as 2 days.
