In a recent study, published in Virology Journal (July 2025), RCB researchers have uncovered around a thousand high-quality viral genomes derived from human gut metagenomic data, largely omitted from existing sequence databases. This includes eight new species of dsDNA- and nineteen new species of ssDNA phages. Four of these genomes are absent in major repositories such as RefSeq, IMG-VR or GPD (Gut Phage Database).
