Abstract

A total of 516 strains of Escherichia coli were screened for the presence and expression of the aerobactin iron uptake system. The incidence was markedly higher among clinical isolates from patients with septicemia (68.8%), pyelonephritis (74.6%), and symptomatic (59.8%) and asymptomatic (63.2%) lower urinary tract infections than among normal human fecal isolates (34.3%).

摘要

共筛选了516株大肠杆菌,以检测气杆菌素铁摄取系统的存在及表达情况。败血症患者的临床分离株(68.8%)、肾盂肾炎患者的临床分离株(74.6%)以及有症状(59.8%)和无症状(63.2%)下尿路感染患者的临床分离株中气杆菌素铁摄取系统的发生率明显高于正常人粪便分离株(34.3%)。
