A total of 109 alpha-hemolytic and 104 nonhemolytic Escherichia coli isolates from children with dyspepsia and urinary tract infections were investigated for resistance to the bactericidal activity of human serum. A significantly higher proportion of serum resistance was found in alpha-hemolytic E. coli isolates than in nonhemolytic isolates (P < 0.01). An association between the titer of alpha-hemolysin produced and serum resistance was found.
对从患有消化不良和尿路感染的儿童中分离出的109株α-溶血大肠杆菌和104株非溶血大肠杆菌进行了对人血清杀菌活性的耐药性研究。发现α-溶血大肠杆菌分离株的血清耐药比例显著高于非溶血分离株(P<0.01)。还发现了所产生的α-溶血素滴度与血清耐药性之间的关联。
