  • Here the authors provide results from a genomic epidemiology study of a cholera outbreak in Lebanon, showing that it was caused by two Vibrio cholerae strains of serogroup O1 (El Tor biotype), namely an AFR15 sublineage related to South Asian isolates and extensively drug-resistant Yemeni AFR13.

  • Since 1970, several cholera outbreaks caused by the “seventh pandemic” (7PET) lineage have been reported in Europe. Here, the authors demonstrate that the outbreaks were caused by repeated introductions of 7PET into Europe, rather than local environmental sources.

  • The genus Serratia includes clinically-important and diverse environmental bacteria. Here, Williams et al. assemble and analyse a representative set of 664 genomes from across the genus, including historic isolates, to provide a genome-based phylogenetic framework for a better understanding of the emergence of clinical and environmental lineages of Serratia.

  • Hawkey et al. provide insights into the spatio-temporal distribution and genetic diversity of Salmonella Paratyphi B — the agent of paratyphoid B fever — and report a genotyping scheme facilitating the international surveillance of this pathogen.

  • An increase in shigellosis cases among men who have sex with men in the United Kingdom has been linked to an extensively drug-resistant strain of Shigella sonnei. In this genomic epidemiology study, the authors investigate the genetic basis, evolutionary history, and international dissemination of the outbreak strain.

  • There have been increasing reports of extensively drug-resistant (XDR) Shigella sonnei infections in recent years. In this laboratory surveillance study from France, the authors document the rise of XDR isolates from 2005 to 2021 and perform whole genome sequencing to investigate their genomic diversity and evolutionary history.

  • Isolates of the Vibrio cholerae O1 serotype Ogawa from Yemen are from a single sublineage of the seventh pandemic El Tor (7PET) lineage and are susceptible to several commonly used antibiotics as well as to polymyxins.
