The distribution of genes encoding different iron acquisition systems in enteroaggregative Escherichia coli (EAEC) from adults with irritable bowel syndrome and from healthy controls was examined using a PCR assay. As many as 95.5% of EAEC carried the chuA gene coding for a haem receptor, and the majority of these strains also had yersiniobactin-encoding genes. Apart from yersiniobactin, enterobactin was the siderophore most frequently associated with EAEC among those strains examined. Genes encoding aerobactin and salmochelin siderophores were less frequent in the group of EAEC.
采用聚合酶链反应（PCR）分析法，检测了来自肠易激综合征成人患者和健康对照者的肠集聚性大肠杆菌（EAEC）中编码不同铁摄取系统的基因分布情况。多达95.5%的EAEC携带编码血红素受体的chuA基因，并且这些菌株中的大多数还具有编码耶尔森菌素的基因。在所检测的菌株中，除了耶尔森菌素外，肠杆菌素是与EAEC最常相关的铁载体。在EAEC组中，编码气杆菌素和沙门菌素铁载体的基因较少见。
