A genome-scale antibiotic screen in Serratia marcescens identifies YdgH as a conserved modifier of cephalosporin and detergent susceptibility

Genetic analyses link the conserved inner membrane protein CvpA to the σEextracytoplasmic stress response

This study identifies CvpA as a regulator of the σE stress response in EHEC, linking it to bile resistance and intestinal colonization.

Shiga toxin remodels the intestinal epithelial transcriptional response to Enterohemorrhagic Escherichia coli

This study investigates how Shiga toxin (Stx) from EHEC infection remodels the intestinal epithelial transcriptional response, highlighting its role in modulating immune signaling and coagulation pathways.

A temperature-dependent translational switch controls biofilm development in Vibrio cholerae

This study identifies a temperature-dependent translational switch mediated by BipA that controls biofilm development in Vibrio cholerae.

An oral inoculation infant rabbit model for Shigella infection

This paper establishes an oral infection model in infant rabbits to study Shigella pathogenesis, showing it replicates human disease features and depends on T3SS and IcsA.

A New Suite of Allelic Exchange Vectors for the Scarless Modification of Proteobacterial Genomes

The paper introduces pTOX vectors for scarless allelic exchange in Proteobacteria, enabling efficient gene modification and antibiotic resistance studies.

Transposon-insertion sequencing screens unveil requirements for EHEC growth and intestinal colonization

This study uses transposon-insertion sequencing to identify genes required for EHEC growth in vitro and in vivo, revealing new factors critical for intestinal colonization.
