Dermatitis or inflammation of the skin caused by an outside agent, is a condition with many causes. It may result from direct irritation of the skin by a substances (chemical or insecticide) or it may be an allergic reaction to a particular substance that has been in contact with the skin as soap or detergent or insect urticating hairs; injected as insect saliva or faeces or sting or taken by mouth as food or drug. In general, treatment of dermatitis depends mainly upon the cause. In the present study, three species of mites were isolated from the dust collected from houses of atopic dermatitis patients. These mites were Dermatophagoides pteronyssinus, Ornithonyssus bacoti and Haemogamasus pontiger. The former species was the predominant one which is known to produce the most potent allergen. It was concluded that house dust mites are one of the aetiological factors of atopic dermatitis and that genera of mites other than Dermatophagoides may be considered as allergen in house dust mites.
由外界因素引起的皮肤炎或皮肤炎症，病因众多。它可能是由某种物质（化学物质或杀虫剂）直接刺激皮肤所致，也可能是对与皮肤接触的特定物质产生的过敏反应，如肥皂、洗涤剂或昆虫的螫毛；通过昆虫唾液、粪便或叮咬注入体内，或通过食物或药物经口摄入。一般来说，皮肤炎的治疗主要取决于病因。在本研究中，从特应性皮炎患者家中收集的灰尘中分离出三种螨虫。这些螨虫分别是粉尘螨、柏氏禽刺螨和格氏血革螨。前一种是主要种类，已知会产生最强效的过敏原。得出的结论是，屋尘螨是特应性皮炎的病因之一，除粉尘螨属之外的其他螨类属也可能被视为屋尘螨中的过敏原。
