The paper identifies PICJIs as large mobile genetic elements in E. coli and Salmonella that spread antimicrobial resistance and defense systems via a specific bacteriophage.

The paper analyzes IncC plasmids from Vibrio cholerae O1 El Tor isolates between 1979 and 2024, revealing their evolution and antimicrobial resistance gene diversity.

The paper uses whole genome sequencing to analyze Vibrio cholerae O1 isolates from 2023-2024 European cholera cases, confirming their lineage and identifying drug-resistant clones.

The paper investigates the integration order of IMEXs in V. cholerae, showing that TLC{Phi} and VGJ{Phi} encode Xer activators that facilitate CTX{Phi} integration, explaining the observed integration order in pandemic lineages.

Flex-It is a genotyping framework for S. flexneri that rapidly characterizes genotypes and resistance determinants from sequencing data, enabling standardized surveillance of its population structure and antimicrobial resistance.

The paper introduces TyphiNET, a dashboard for exploring Typhi genomics data to support public health decisions on antimicrobial resistance and vaccine implementation.

The paper provides 15 genomically characterized Shigella sonnei isolates representing diverse sub-clades, with complete genome sequences and public availability for research.

This study characterizes a two-strain cholera outbreak in Lebanon using genomic analysis, revealing the coexistence of two distinct Vibrio cholerae strains with different antibiotic resistance profiles.

This study evolves a virulent phage to expand its host range and increase virulence, finding convergent mutations in key genes.

This study analyzes 836 Salmonella Panama genomes to reveal population structure, antimicrobial resistance, and genetic markers of invasiveness across global regions.

This study compares serotyping and cgMLST for Shigella classification, finding that cgMLST better reflects genetic relationships.
