Metabolite analysis of plasma from enteric fever patients define signals of organism specific host–pathogen interactions and provides opportunities for new diagnostics.

Among children in low-resource settings, diverse enteropathogens share common, population-level antibody dynamics, which creates a new opportunity to estimate transmission through serologic surveillance.

A response regulator acquired via lateral gene transfer has rewired an ancestral genetic circuitry and regulates alternative pathogenic lifestyles.

A fluoroquinolone resistant variant of Salmonella Typhi has emerged that is likely to be widespread in the Indian subcontinent; therefore fluoroquinolones should not be recommended for empirical typhoid fever therapy in this setting.

The major evolutionary routes to drug resistance in Salmonella Typhi are associated with fitness benefits, not fitness costs, implying that prudent antimicrobial use will have no effect as a public health intervention in controlling typhoid fever.

Inside the acidic vacuole, expression, DNA binding and DNA binding affinity of the Salmonella regulator SsrB is stimulated by acid pH.

SafDAA-SafDAA structure and functional characterizations reveal a pili-mediated inter-cellular oligomerization mechanism for bacterial aggregation and biofilm formation in Salmonella enterica.

Biochemical analyses and the crystal structure of TtsA reveal fundamental insight into the mechanisms by which this muramidase recognizes its peptidoglycan substrate to facilitate typhoid toxin secretion.

Visualization of the type III secretion mediated Salmonella-host cell interface reveals the intact translocon and the profound remodeling of the host membrane at unprecedented resolution.
