Cerumen is the product of the secretion of the sebaceous, ceruminous or apocrine glands together with cells exfoliated from the cornified stratum of the epithelium of the external auditory canal (EAC). In the present study we identified and quantified common flora of human cerumen. The mean count obtained was 10(6) microorganisms per ml of cerumen suspension. In 24 pools of cerumen (33.3 per cent) the isolates were monomicrobial, Staphylococcus epidermidis (12), Corynebacterium spp (10), Staphylococcus aureus (1) and Streptococcus saprophyticum (1). In 48 pools (66.6 per cent) we found polymicrobial isolates. The most commonly isolated bacteria in these polymicrobial isolates were S. epidermidis (35) and Corynebacterium spp. (43). It is noteworthy that there were isolates of Candida albicans in three cases; in one case of Pseudomonas stutzeri, in one case of Pseudomonas aeruginosa, and, on seven occasions, of S. aureus. The organisms isolated as common bacterial components of human cerumen in our experience were similar to those found by other authors. However, the mean count was much higher. This could be related to climatic conditions and to the length of time the cerumen had remained in the external auditory canal.
耵聍是皮脂腺、耵聍腺或大汗腺的分泌物与外耳道（EAC）上皮角质化层脱落的细胞共同形成的产物。在本研究中，我们鉴定并量化了人类耵聍中的常见菌群。每毫升耵聍悬液的微生物平均计数为10⁶个。在24份耵聍样本（占33.3%）中，分离出的菌株为单一微生物，其中表皮葡萄球菌12株、棒状杆菌属10株、金黄色葡萄球菌1株、腐生葡萄球菌1株。在48份样本（占66.6%）中，我们发现了多种微生物的分离株。这些多种微生物分离株中最常分离出的细菌是表皮葡萄球菌（35株）和棒状杆菌属（43株）。值得注意的是，有3例分离出白色念珠菌；1例分离出施氏假单胞菌，1例分离出铜绿假单胞菌，还有7例分离出金黄色葡萄球菌。根据我们的经验，作为人类耵聍常见细菌成分分离出的微生物与其他作者发现的相似。然而，平均计数要高得多。这可能与气候条件以及耵聍在外耳道中停留的时间长短有关。
