Abstract

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.

摘要

迄今为止，铁载体模式分析包括生物测定，以检测肠杆菌素、气杆菌素和肠杆菌科的其他铁载体。此外，肠杆菌素的前体2,3 - 二羟基苯甲酸和新的异羟肟酸铁载体可以通过两种新的沙门氏菌突变体作为指示菌株进行检测。通过这种方式，铁载体模式分析扩展了其鉴别能力。在测试的167株鼠伤寒沙门氏菌菌株中，我们检测到5种铁载体模式。在总共204株大肠杆菌菌株中可检测到6种铁载体模式。使用铁载体模式分析用于临床流行病学和生态学目的时，可以推荐合适的技术方法。
