During infection of their hosts, salmonellae enter intestinal epithelial cells. It has been
proposed that when Salmonellatyphimurium is present in the intestinal lumen, several …

Iron is essential for all organisms but can be toxic in excess. Iron homeostasis is typically
regulated by cytoplasmic iron binding proteins, but here we describe a signal transduction …

In many pathogens, virulence can be conferred by a single region of the genome. In
contrast, the facultative intracellular lifestyle of Salmonella demands a large number of …

Pathogenicity islands are chromosomal clusters of horizontally acquired virulence genes
that are often found at tRNA loci. The selC tRNA locus of Escherichia coli has served as the …

A range of bacteria are able to use tetrathionate as a terminal respiratory electron acceptor.
Here we report the identification and characterization of the ttrRSBCA locus required for …

The PhoP-PhoQ two-component system is essential for virulence in Salmonella
typhimurium. This system controls expression of some 40 different proteins, yet most PhoP …

The PmrA-PmrB two-component system of Salmonella typhimurium controls resistance to
the peptide antibiotic polymyxin B and to several antimicrobial proteins from human …

The green fluorescent protein (GFP) from Aequorea victoria is a novel fluorescent marker
that has potential use in the study of bacterial pathogenicity. To explore some of the potential …

Abstract The PmrA–PmrB two‐component system of Salmonella enterica controls resistance
to the peptide antibiotic polymyxin B and to several antimicrobial proteins from human …

One of the most virulent and feared bacterial pathogens is Yersinia pestis, the aetiologic
agent of bubonic plague. Characterization of the O‐antigen gene clusters of 21 serotypes of …
