Gene Sequencing Might Help Track Spread of Latest Coronavirus in China

Gene Sequencing Might Help Track Spread of Latest Coronavirus in China- Next-generation sequencing (NGS) is used to monitor how viruses spread and evolve in animals, but routine and large-scale monitoring with NGS can be expensive and labor-intensive, and can miss less abundant viral markers in samples. Those issues have led geneticists to develop less costly and more efficient gene sequencing strategies. In a new study, researchers outline a new enrichment strategy for monitoring coronaviruses, especially those that originate in bats. In this approach, the gene sequencing is “enriched” with what the researchers call probes. They’re tiny fragments of genetic material that find and bind to viral DNA, and they could provide a quick way to identify where viral genetic material might be hiding.In tests, the probes successfully identified coronaviruses, and this enrichment approach increased sensitivity and reduced sequencing costs. They said this approach could help them maintain a library of genetic material from emerging coronaviruses, and track the origin and evolution of coronaviruses that cause outbreaks.
