A sample of fourteen horse rugs and two saddle blankets stored in south western Sydney, Australia, an area of known high dust mite prevalence in the human environment, were analysed for the presence of house dust mites. Dust samples from the rugs, blankets and 16 control sites were collected using a vacuum cleaner with a modified attachment and filter. Dust mites were extracted using an adapted floatation technique. Eight rugs and all control samples were positive for mites, which were confirmed to be house dust mites of the genus Dermatophagoides. This study confirms that exposure to house dust mites from horse rugs can occur, indicating that house dust mite allergen reactivity on intradermal and serum allergy testing in atopic horses may represent true dust mite hypersensitivity. Nevertheless, quantification studies will be necessary to ensure that there is adequate mite exposure for development of hypersensitivity, and further evaluation of immunological responses, avoidance and provocation, and specific immunotherapy are required to confirm the clinical relevance. To the authors' knowledge, this is the first study to document the presence of house dust mites in the equine environment.
对存放在澳大利亚悉尼西南部的14条马毯和2条马鞍毯样本进行了分析，以检测屋尘螨的存在情况。该地区在人类环境中已知屋尘螨患病率很高。使用带有改良附件和过滤器的真空吸尘器收集来自马毯、马鞍毯以及16个对照地点的灰尘样本。采用改良的漂浮技术提取尘螨。8条马毯和所有对照样本的螨虫检测呈阳性，经确认这些螨虫为尘螨属的屋尘螨。这项研究证实，有可能接触到来自马毯的屋尘螨，这表明特应性马匹皮内和血清过敏试验中对屋尘螨过敏原的反应可能代表真正的尘螨过敏。然而，需要进行定量研究以确保有足够的螨虫接触量来引发过敏，还需要进一步评估免疫反应、避免接触和激发试验，以及特异性免疫疗法，以确认其临床相关性。据作者所知，这是第一项记录马环境中存在屋尘螨的研究。
