Salmonella enterica serovar Typhimurium is a primary enteric pathogen infecting both
humans and animals. Infection begins with the ingestion of contaminated food or water so …

In the ancient anaerobic environment, ferrous iron (Fe2+) was one of the first metal
cofactors. Oxygenation of the ancient world challenged bacteria to acquire the insoluble …

A series of vectors has been developed to provide improved positive and negative selection
for allelic exchange. Based on homologous regions of DNA ranging in size from less than …

H‐NS is a small chromatin‐associated protein found in enterobacteria. H‐NS has affinity for
all types of nucleic acids but binds preferentially to intrinsically curved DNA. The major role …

dsrA encodes a small, untranslated RNA. When over‐expressed, DsrA antagonizes the H‐
NS‐mediated silencing of numerous promoters. Cells devoid of DsrA grow normally and …

Summary Bis‐(3′− 5′)‐cyclic‐di‐guanosine monophosphate (c‐di‐GMP) is a bacterial
signalling molecule produced by diguanylate cyclases (DGC, carrying GGDEF domains) …

A list of currently identified gene products of Escherichia coli is given, together with a
bibliography that provides pointers to the literature on each gene product. A scheme to …

A sudden increase in the osmolarity of the environment is highly detrimental to the growth
and survival of Fscherichia coli and Salmonella typhimurium since it triggers a rapid efflux of …

Curli encoded by the c urlin s ubunit gene, csgA, are fibronectin‐and laminin‐binding fibres
expressed by many natural Escherichia coli and E. coli K‐12 strains in response to low …

The rpoS‐encoded sigma (S) subunit of RNA polymerase is a central regulator in a
regulatory network that governs the expression of many stationary phase‐induced and …
