Freshly collected cerumen (dry form) suspended at a concentration of 3% in glycerol-sodium bicarbonate buffer showed bactericidal activity against some strains of bacteria tested. This suspension reduced the viability of Haemophilus influenzae, Escherichia coli K-12, and Serratia marcescens by more than 99%, whereas the viability of two Pseudomonas aeruginosa isolates, E. coli K-1, Streptococcus, and two Staphylococcus aureus isolates of human origin was reduced by 30 to 80%. The results support the hypothesis that cerumen functions to kill certain foreign organisms which enter the ear canal.
新鲜采集的耵聍（干型）以3%的浓度悬浮于甘油 - 碳酸氢钠缓冲液中，对所测试的一些细菌菌株显示出杀菌活性。该悬浮液使流感嗜血杆菌、大肠杆菌K - 12和粘质沙雷氏菌的活力降低了99%以上，而两种铜绿假单胞菌分离株、大肠杆菌K - 1、链球菌以及两种人源金黄色葡萄球菌分离株的活力降低了30%至80%。这些结果支持了耵聍具有杀死进入耳道的某些外来生物体这一假说。
