Prophages are phages hidden in bacterial genomes, and they affect our health! We explored where they hang out in the human microbiome biorxiv.org/content/10.1101/…

Prophage rates in the human microbiome vary by body site and host health

Phages integrated into a bacterial genome–called prophages–continuously monitor the health of the host bacteria to determine when to escape the genome, protect their host from other phage infections,...

RT @feargal@genomic.social My old lab from Cork, Ireland in Nature this week with "Structural atlas of a human gut crassvirus". Really great team, always so supportive, friendly and hard working, really well earned! Plus such nice pictures. (Damn maybe I should have stayed (1/2)

Scientists discover why sea urchins are dying off from US to the Caribbean

A research team has discovered a parasite that’s been killing off sea urchins, but there’s no method to eliminate it yet

Not all proteins arise from consecutive codons. We developed a new tool - PRFect - to identify programmed ribosomal frameshifts. Designed, built, trained, and tested with #phage genomes, it also works on #bacteria and #eukaryotes too. biorxiv.org/content/10.1101/…

Programmed ribosomal frameshifts, and how to find them

One of the stranger phenomena that can occur during gene translation is where, as a ribosome reads along the mRNA, various cellular and molecular properties contribute to stalling the ribosome on a...

Diverse and abundant viruses exploit conjugative plasmids

Viruses exert profound evolutionary pressure on bacteria by interacting with receptors on the cell surface to initiate infection. While the majority of bacterial viruses, phages, use chromosomally-...

That depends a bit on your definition of host range. Just recognition / lysis or also plaque formation? Phages targeting the highly conserved NGR glycan of enterobacteria are quite broad or those targeting conjugative pili of broad host-range plasmids (even cross-genus for PRD1).
