Tyrophagus putrescentiae (Schrank) (Acaridae) is one of the most allergenic mite species worldwide, and it particularly infests household environments, animal feed factories, and food factories. It has been the aim of several studies recently in the healthcare area due to its allergenic potential. However, there had been no records of this species attacking laying birds until this report. This is the first record of adverse reactions in animals triggered by infestations of this species. Therefore, the present study aims at describing the damages and symptomatology of T. putrescentiae infestations on commercial laying hens. Alopecia and dermatitis were symptoms exacerbated by T. putrescentiae infestation starting at 40 weeks old. The presence of this species on hens, as observed in the present study, might be directly related to the accumulation of food and poultry litter on these birds, in their cages, or in the vicinities. Hence, the results might be related to their feeding behavior, which consists of continuous supply of animal feed in these management systems. The present study provides an unprecedented record that reveals the importance and potential for emergency pest status of T. putrescentiae in the poultry industry. Its infestations in poultry houses probably required constant sanitary care and monitoring are required in order to prevent outbreaks of this mite.
腐食酪螨（Schrank）（粉螨科）是世界上最具过敏原性的螨种之一，特别栖息在家庭环境、动物饲料厂和食品厂中。由于其潜在的过敏原性，它最近成为医疗保健领域的几项研究的目标。然而，在此报告之前，没有关于这种物种攻击产蛋鸟类的记录。这是首例由该物种侵袭引发的动物不良反应记录。因此，本研究旨在描述腐食酪螨对商业产蛋母鸡的侵袭所造成的损害和症状。从 40 周龄开始，腐食酪螨的侵袭会加剧脱毛和皮炎等症状。在本研究中观察到的这种物种在母鸡身上的存在，可能与它们笼子里或周围堆积的食物和家禽垃圾直接相关。因此，结果可能与它们的进食行为有关，在这些管理系统中，它们会不断供应动物饲料。本研究提供了一个前所未有的记录，揭示了腐食酪螨在禽类养殖业中的重要性和潜在紧急虫害状态。在禽舍中，为了防止这种螨虫的爆发，可能需要持续的卫生护理和监测。
