Identification of a new iron regulated locus of Salmonella typhi.

Abstract

In order to identify genes belonging to the Fur regulon of Salmonella typhi which are absent from Escherichia coli K-12, a plasmid gene bank consisting of 4000 independent clones was screened for Fur regulated promoters using the Fur titration assay (FURTA). DNA probes generated from FURTA positive plasmids were then used for hybridization with chromosomal… (More)
