The bactericidal activity of twenty disinfectants against S. aureus was evaluated by a suspension and capacity test. The effect of interfering substances (organic matter and hard water) on the activity of these disinfectants was investigated by a number of experimental trials. The sensibility of S. aureus to sodium laurylsulfate and zinc pyrithione was affected by proteins. The interference of proteins was not evident for the other disinfectants. The polyvinylpyrrolidone-iodine 7% and the cresol saponatum tolerated the presence of proteins in distilled water, but they were influenced by them in hard water; on the contrary, the zinc pyrithione was more active in hard water than in distilled water. Generally, the second and third incremental addition of microorganisms did not practically alter the bactericidal effect of the majority of disinfectants.
通过悬浮和容量试验评估了20种消毒剂对金黄色葡萄球菌的杀菌活性。通过一系列实验研究了干扰物质（有机物和硬水）对这些消毒剂活性的影响。金黄色葡萄球菌对十二烷基硫酸钠和吡硫翁锌的敏感性受蛋白质影响。蛋白质对其他消毒剂的干扰不明显。7%聚维酮碘和甲酚皂在蒸馏水中能耐受蛋白质的存在，但在硬水中会受到其影响；相反，吡硫翁锌在硬水中比在蒸馏水中更具活性。一般来说，第二次和第三次增加微生物添加量实际上并未改变大多数消毒剂的杀菌效果。
