Nicolas Kieffer (Universidad Complutense de Madrid) and colleagues published a new preprint on identification of phage defense systems encoded by mobile integrons, showing that integrons can encode phage defense systems, including Lamassu,

The Société Française de Bioinformatique, Lyon, France is hiring a Master's level bioinformatician to study the phageomes and counter-defensomes of microbial communities.

Florian Tesson (Institut Pasteur) and colleagues published a new paper on the DefenseFinder webservice/wiki/database for antiphage defense mechanisms, showing an updated resource with 152 identified systems.

From David Bikard via Twitter: Hello phage phriends. Do you have examples of anti-phage defense systems that were shown to tolerate lysogeny but target the phage when it enters its lytic cycle ? (beyond type III CRISPR)

Pieter-Jan Haas’ group at UMC Utrecht is seeking a postdoc to identify the most relevant defense and counter defense mechanisms in clinical strains and phages of the bacterial pathogen P. aeruginosa.

Ana Rita Costa (Delft University of Technology) and colleagues published a new paper showing that clinical P. aeruginosa strains accumulate phage defense systems (some have at least 19!), that many individual defense systems target specific

From David Bikard via Twitter: A question to the phage aficionado. Do you have clear examples of anti-phage defense systems that block the production or assembly of phage particles without targeting the phage DNA and without resulting in ce

The Atkinson lab at Lund University, Sweden are seeking a bioinformatics PhD student to be involved in the Novo Nordisk funded project: ‘Development of phage biocontrol to overcome the antiphage defense system arsenal of phytopathogenic Ral

The Friman lab at the University of Helsinki, Finland is hiring a postdoc to develop phage biocontrol to overcome the antiphage defense system arsenal of phytopathogenic Ralstonia solanacearum bacterium.

The Fossati lab at the Karolinska Institutet, Sweden is hiring a postdoc in the field of bacterial antiphage systems. The lab investigates bacterial immune system composition and mechanisms by employing bulk NGS and high-throughput proteomi

Kishen Patel and Kimberley Seed (University of California, Berkeley) published a new preprint on how a sporadic phage defense in epidemic Vibrio cholerae (mediated by the toxin-antitoxin system DarTG) is countered by a phage-encoded antitox

Mikhail Skutel and colleagues demonstrate how the T5-like phage BF23 evades host-mediated DNA restriction and methylation.

Ana Cristina Afonso Oliveira (CEB at University of Minho, Braga, Portugal) is seeking a PhD student to study phages to overcome ETEC's phage defence systems.

Lydia Chambers and colleagues discovered that bacterial antiviral defense pathways encode eukaryotic-like ubiquitination systems, revealing strong parallels between bacterial and eukaryotic ubiquitination pathways.

The research group of Dr Andrea Fossati at Karolinska Institute, Sweden seeks a postdoc to study phage defense systems in mycobacteria.

The Frunzke lab (Forschungszentrum Jülich, Germany) is seeking a PhD student to study bacterial antiviral immunity.

Washington University is hiring a Research Technician II - Molecular Microbiology to study the molecular arms race between bacteria and these viruses by discovering and characterizing new bacterial phage defense mechanisms.

Elliot Macdonald and colleagues at Newcastle University have identified a new anti-phage system called Shield, found in Pseudomonas, made of a core component ShdA and a membrane-bound protein with an RmuC domain, which provides a new mechan

The LeRoux lab at Washington University School of Medicine is seeking a postdoc to investigate phage defense mechanisms in opportunistic pathogens. This study will inform efforts to develop phage therapy against high priority pathogens.

Tanita Wein and colleagues have published a new preprint on caspase recruitment domains (CARDs), which play a crucial role in inflammasome activity and pyroptosis. They found that CARD-like domains are present in phage defense systems, and
