The hemolytic activity of 32 vaginal isolates of Staphylococcus aureus from patients with typical toxic shock syndrome (TSS) was contrasted with that of 50 vaginal isolates from patients without TSS, using a standardized inoculum (10(5) CFU) on 5% sheep blood agar after 48 h of incubation under 30% CO2. Additionally, 7 nongenital isolates from patients with nonmenstrual TSS and 57 strains of nongenital control isolates were included for comparison. Vaginal TSS strains were significantly less hemolytic than non-TSS S. aureus strains of either genital (P less than 0.001) or nongenital (P less than 0.01) origin. Vaginal TSS S. aureus strains were also less hemolytic than were nongenital TSS S. aureus strains (P less than 0.02). This reduced hemolytic activity of genital TSS S. aureus strains may provide a useful marker for screening and further delineation of toxigenic S. aureus associated with menstrually related TSS.
将来自典型中毒性休克综合征(TSS)患者的32株阴道分离金黄色葡萄球菌的溶血活性,与来自无TSS患者的50株阴道分离菌的溶血活性进行对比,使用标准化接种物(10⁵CFU)接种于5%绵羊血琼脂平板上,在30%二氧化碳条件下孵育48小时。此外,纳入了7株来自非经期TSS患者的非生殖道分离菌和57株非生殖道对照分离菌株用于比较。阴道TSS菌株的溶血活性显著低于生殖道(P<0.001)或非生殖道(P<0.01)来源的非TSS金黄色葡萄球菌菌株。阴道TSS金黄色葡萄球菌菌株的溶血活性也低于非生殖道TSS金黄色葡萄球菌菌株(P<0.02)。生殖道TSS金黄色葡萄球菌菌株溶血活性的降低可能为筛查和进一步界定与经期相关TSS相关的产毒金黄色葡萄球菌提供一个有用的标志物。
