title: [The role of iron-regulated genes in microbial pathogenesis].
abstract: An important component of nonspecific defence of human or animal organisms against microbial invasion is attempt to withhold growth-essential iron from invading bacteria. To overcome the barrier bacterial iron uptake systems is derepressed at low iron concentrations. In many pathogenic and nonpathogenic bacteria the regulation of the corresponding genes depends on the regulatory protein Fur. For cloning Fur-regulated loci, methods based on affinity of Fur to the corresponding promoter sites are used.
