Different systems for iron supply of Salmonella typhimurium and Escherichia coli wild strains as tool for typing.
Hitherto the siderophore-pattern analysis included bioassays to detect enterobactin,aerobactin and other siderophores of Enterobacteriaceae. In addition, 2,3-dihydroxybenzoic acid, the precursor of enterobactin, and new hydroxamate siderophores could be examined by means of two new Salmonella mutants as indicator strains. In this manner the siderophore pattern analysis extends its discriminating ability. Among 167 Salmonella typhimurium strains tested, we detected 5 siderophore patterns. 6 siderophore patterns could be detected among a total of 204 E. coli strains. Using siderophore pattern analysis for clinical-epidemiological and ecological purposes appropriate technical methods can be recommended.
