Today, our UPOBioinfo group presents the defensome of Acinetobacter baumannii.
Do you know about its concerning Global Clone 2? Well, part of its success could be due to the replacement of restriction-modification systems by Ssp antiviral systems.

A family of linear plasmid phages that detect a quorum-sensing autoinducer exists in multiple bacterial species Temperate phages oscillate between lysogeny, a genomic maintenance state within a bacterial host, and lytic replication, in which the host is killed, and newly made phage particles are released. Successful transmission to new hosts requires that temperate phages appropriately time their transitions from lysogeny to lysis. It is well understood that temperate phages trigger lysis upon detection of host cell stress. Understanding of the breadth of cues that induce lysis expanded with the discovery of phages carrying quorum-sensing receptor genes that promote lytic induction exclusively at high host cell density. Bacteria engage in a cell-cell communication process called quorum sensing, which relies on the production, release, accumulation, and group-wide detection of extracellular signal molecules called autoinducers. Bacteria use quorum sensing to monitor changes in population density and synchronize collective behaviors. The temperate phage VP882 (jVP882) encodes VqmAj – a homolog of its host’s quorum-sensing receptor/transcription factor VqmA. VqmAj allows jVP882 to detect the accumulation of the host autoinducer called DPO. Presumably, launching the lytic induction program at high host cell density maximizes jVP882 transmission to new hosts. Here, by mining sequence databases for linear plasmid phages, we identify VP882-like phages in multiple DPO-producing bacterial species isolated at diverse times and geographic locations. We show that the VqmAj homologs can indeed detect DPO and, in response, activate the lytic pathway. Our observation indicates that jVP882 is a member of a large family of globally-dispersed quorum-sensing-responsive temperate phages.
