Bacteria can exchange nutrients and macromolecules through tubular membranous structures called nanotubes. Here, the authors show that Bacillus subtilis can kill and prey on Bacillus megaterium by delivering a toxin and extracting nutrients in a nanotube-dependent manner.
The evolutionary function of natural competence remains controversial and several hypotheses for a function have been proposed. In this Opinion article, Veening and Blokesch propose that kin-discriminated predation that is linked to natural competence serves as a DNA acquisition strategy and therefore contributes to bacterial evolution.
In this Review, Spaan, van Strijp and Torres discuss the implications of the identification of the cellular receptors for the Staphylococcus aureus bi-component leukocidins, the mechanisms of action of the leukocidins, their diverse roles during pathogenesis and their potential as targets for therapeutic interventions.
Type VII protein secretion systems are most widely associated with virulence in bacterial pathogens. A new study reveals a type VII system-secreted nuclease toxin that specifically affects clonally unrelated strains, thus placing type VII secretion directly into the fray of microbial competition.
Persister formation by S. Typhimurium involves the acetylation of aminoacyl-tRNAs by the toxin–antitoxin module toxin TacT, which can be reversed by an antitoxin-independent mechanism that enables S. Typhimurium to resume growth.
