TL;DR: Data suggest that viruses of the non-tailed dsDNA DJR lineage are important but often overlooked predators of bacteria and archaea that impose fundamentally different predation and gene transfer regimes on microbial systems than on tailed viruses, which form the basis of all environmental models of bacteria–virus interactions.

TL;DR: In this paper, the authors describe a recent adaptive radiation leading to fine-scale ecophysiological differentiation in the degradation of an algal glycan in a clade of closely related marine bacteria.

TL;DR: A metric of recent gene flow is introduced, which when applied to co-existing microbes, identifies congruent genetic and ecological units separated by strong gene flow discontinuities from their next of kin, to facilitate the analysis of bacterial and archaeal genomes using ecological and evolutionary theory developed for plants and animals.

TL;DR: This article found that susceptibility to viral killing in marine Vibrio is mediated by large and highly diverse mobile genetic elements, which display exceedingly fast evolutionary turnover, resulting in differential phage susceptibility among clonal bacterial strains while phage receptors remain invariant.

TL;DR: The findings demonstrate that existing influenza-specific memory and route of exposure influence influenza immunity, and reveal that both preexisting immunity and exposure type shape protective antibody responses to conserved influenza virus epitopes in humans.
