Kristen LeGault (University of California, Berkeley) and colleagues published a new preprint showing how temporal shifts in antibiotic resistance elements govern virus-pathogen conflicts in Vibrio cholerae recovered from clinical samples. T

Charles Bernard (CNRS, France) and colleagues published a new paper in the ISME Journal describing their identification of a new communication system that may regulate host defense mechanisms (similar to the arbitrium system) in Bacillus ph

Viperins are known to function in the eukaryotic antiviral response, and now they've been found in prokaryotes. Aude Bernheim (Weizmann Institute of Science) and colleagues published a new paper in Nature on prokaryotic viperins, which prot

Linyi Gao (Howard Hughes Medical Institute, Cambridge, MA) and colleagues published a new paper in Science describing their discovery of 29 new phage-protective gene cassettes, many of which incorporate enzymatic activities not previously i

Cyclic-oligonucleotide-based anti-phage signalling systems (CBASS) share ancestry with an innate immune pathway in animals. Adi Millman (Weizmann Institute of Science, Israel) and colleagues published a new paper in Nature Microbiology on C

Siân Owen (Harvard Medical School) and colleagues published a new preprint on a new prophage-encoded defense protein that simultaneously suppresses phage epidemics in a population (through abortive infection) and provides self-immunity to t

Retrons are bacterial genetic elements comprised of a reverse transcriptase (RT) and a non-coding RNA, but their functions have been unknown for decades. Adi Millman (Weizmann Institute of Science, Israel) and colleagues published a new pre

The Bikard Lab (Institut Pasteur, Paris) is hiring a postdoc to study the properties of Cas proteins in bacteria, their interaction with DNA repair pathways, and the mechanism and evolution of CRISPR-Cas systems as phage defense systems

Shannon Slattery (University of Limerick, Ireland) and colleagues published a new paper in Scientific Reports describing the isolation of a Proteus mirabilis strain from wastewater harbouring an integrative conjugative element (ICE) contain

Shweta Karambelkar (Indian Institute of Science) and colleagues published a interesting report on how phage Mu uniquely protects its DNA from diverse host defense systems in Nucleic Acids Research. They characterized Mu's "Mom" protein, whi

Oliver Bezuidt (University of Pretoria, South Africa) and colleagues published a new paper in mSystems that sheds light on Antarctic phage-host interactions. Their metagenomic analysis picked up DISARM, BREX and CRISPR-Cas defense systems i
