A compendium of critical genomic numbers for viruses through the lenses of different viral classification systems.

From public microbial genomes, VirSorter revealed 12,498 viral genome sequences that expand the map of the global virosphere and whose analyses improve understanding of viral taxonomy, evolution and virus-host interactions.

The characterization of ancient B19V and HBV genotype A4 viruses circulating during Colonial epidemics provides new insights into the pathogens that were introduced to the Americas after the European colonization.

The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.

Single-cell amplified genome sequencing uncovers virus-host interactions in uncultivated sulfur-oxidizing bacteria with relevance to coupled biogeochemical cycling in marine oxygen minimum zones.

A bioinformatics pipeline has annotated over 2,500 complete genomes of circular DNA viruses belonging to dozens of established and emerging viral families.

An innovative strategy in genome analysis has generated a detailed description of how pathogens mutate when facing human genetic diversity.

Newly discovered viruses in dead and dying farmed Chinook salmon are widely distributed in threatened wild Chinook and sockeye salmon populations.

SiR does not revert to wild type when produced in high-TEVp cell lines, is non-toxic in vivo, maintains transsynaptic spreading capabilities and revertant mutations do not accumulate during in vivo experiments.

SARS-CoV-2 can spread efficiently within care homes causing outbreaks among residents, who are at increased risk of severe disease, emphasising the importance of stringent infection control in this population.
