Several preparations of staphylococcal alpha-toxin and delta-lysin were studied in order to compare hemolytic activity with capacity to lyse bacterial protoplasts. delta-Lysin in relatively low concentration lysed protoplasts of Sarcina lutea, protoplasts of Streptococcus faecalis, and spheroplasts of Escherichia coli. Lysis of bacterial protoplasts by preparations of alpha-toxin appeared to be due to contamination of the preparations with delta-lysin. Data comparing the protoplast-lysing activity of various lytic agents are presented.
为了比较溶血活性和裂解细菌原生质体的能力,对几种葡萄球菌α毒素和δ溶血素制剂进行了研究。相对低浓度的δ溶血素可裂解藤黄八叠球菌的原生质体、粪链球菌的原生质体以及大肠杆菌的球状体。α毒素制剂对细菌原生质体的裂解似乎是由于制剂被δ溶血素污染所致。文中给出了比较各种裂解剂原生质体裂解活性的数据。
