Impaired acid stress resistance in Salmonella Typhi Ty2

This study compares acid stress resistance between Salmonella Typhimurium and Salmonella Typhi, finding that Typhi has impaired growth at acidic pH due to gene loss and pseudogenization.

The MarR Family Transcription Factor SlyASenses Iron and Respiratory Status in Enteric Bacteria

This study identifies aromatic carboxylates as endogenous ligands for SlyA, a MarR family transcription factor, showing it senses iron availability, respiration, and metabolic state in enteric bacteria.

Evasion of serum antibodies and complement by Salmonella Typhi and Paratyphi A

This study compares how Salmonella Typhi and Paratyphi A evade serum antibodies and complement compared to S. Typhimurium, identifying differences in O-antigen and Vi capsule production.

A cytochrome bd repressed by a MarR family regulator confers resistance to metals, nitric oxide, sulfide, and cyanide in Chromobacterium violaceum

This paper identifies a cytochrome bd (CioAB) in Chromobacterium violaceum that confers resistance to multiple stressors, including metals, nitric oxide, and cyanide, and shows it is regulated by a MarR family repressor and quorum sensing.
