In 2019, an outbreak of Shigella sonnei occurred during two youth camps in Belgium. The clustering of isolates from both camps was confirmed by next-generation sequencing, as well as a secondary infection of a technician. The outbreak strain clustered with internationally isolated strains from patients with recent travel history to Central America. This report exemplifies enhanced surveillance and international collaboration b...

Summary We examined the genetic diversity of lytic Pseudomonas aeruginosa bacteriophage PB1 and four closely related phages (LBL3, LMA2, 14‐1 and SN) isolated throughout Europe. They all encapsulate linear, non‐permuted genomes between 64 427 and 66 530 bp within a solid, acid‐resistant isometric capsid (diameter: 74 nm) and carry non‐flexible, contractile tails of approximately 140 nm. The genomes are organized into at least...
