BACKGROUND/PURPOSE: Two Demodex species are known to live on people. Demodex folliculorum lives in the openings of hair follicles alone or in groups. D brevis lives in the depths of the sebaceous glands alone. There are different related on the epidemiology of Demodex species have been published.
In this study, taking into account that the parasite is transmitted through close contact from person to person, we aimed to evaluate the relation between the presence of Demodex spp with gender and age among the Health hazard bearing and sanitary establishment operators and workers who came for porter examination.
For this purpose, 862 male and 215 female patients with a total of 1077 volunteers from the face area of the standard superficial skin biopsy (SSSB) method and studied samples were taken. More than five mites in 1 cm(2) density was defined as positive. In investigated samples 37.3% Demodex spp. positivity was detected. Only two were found to be D brevis and the others were D folliculorum. The study revealed statistically significant relationships between the positivity of parasites with the occupational group, age and sex.
Since the prevalence of Demodex among healthy individuals without any complaint was found to be 37%, we believe Demodex spp should be investigated in porter examinations of people who have dermatological complaints.
背景/目的：已知有两种毛囊蠕形螨生活在人类身上。毛囊蠕形螨单独或成群生活在毛囊的开口处。短毛蠕形螨单独生活在皮脂腺的深处。已经发表了关于毛囊蠕形螨流行病学的不同相关研究。
在这项研究中，考虑到寄生虫是通过人与人之间的密切接触传播的，我们旨在评估在健康危害携带者和卫生机构操作人员和工人中，Demodex spp 的存在与性别和年龄之间的关系，这些人是来进行搬运工检查的。
为此，我们从面部区域采集了 862 名男性和 215 名女性共 1077 名志愿者的标准浅表皮肤活检（SSSB）方法的研究样本。将每 1cm² 密度超过 5 只螨虫定义为阳性。在调查的样本中，检测到 37.3%的 Demodex spp.阳性。仅发现两种是短毛蠕形螨，其余都是毛囊蠕形螨。研究表明，寄生虫的阳性与职业群体、年龄和性别之间存在统计学显著关系。
由于在没有任何投诉的健康个体中发现毛囊蠕形螨的患病率为 37%，我们认为在有皮肤投诉的人群中进行搬运工检查时，应该调查毛囊蠕形螨。
