The lysis of human erythrocytes by Staphylococcus aureus delta-toxin proceeded without a lag and was directly proportional to toxin concentration and temperature of incubation. Lysis was complete within 8 min. Addition of saturated, straight-chain fatty acids of 13 to 19 carbons increased the activity of delta-toxin, whereas those with 21 to 23 carbons were inhibitory. Palmitic acid was the fatty acid most active in augmenting delta-toxin, but its effect could be abolished by the simultaneous addition of either tricosanoic acid or egg lecithin.
金黄色葡萄球菌δ-毒素对人红细胞的裂解过程没有延迟,且与毒素浓度和孵育温度成正比。8分钟内裂解完成。添加13至19个碳的饱和直链脂肪酸可增强δ-毒素的活性,而21至23个碳的脂肪酸则具有抑制作用。棕榈酸是增强δ-毒素活性最有效的脂肪酸,但其作用可被同时添加的二十三烷酸或卵磷脂消除。
