, also known as the poultry red mite (PRM), is a blood-feeding ectoparasite of poultry and sylvatic birds. This mite is endemic in many parts of the globe and poses a threat to the egg industry, while compromising the health and welfare of hens, both directly and as a vector of diseases. In addition, people attacked by may develop gamasoidosis. Despite the high prevalence in several European countries, epidemiological information on in Portugal is scarce. This study aimed to assess the prevalence and infestation levels in laying farms in Portugal and evaluate the perception and attitudes of producers regarding . A survey was performed between August 2016 - November 2017, which included 24 farms in the NUTS2 regions Centro and Norte. Mites were sampled with corrugated cardboard traps and the perception and attitudes of farmers regarding the PRM were evaluated with the European COREMI questionnaire prepared by WG 1 of the COST action FA1404. was detected in 95.8% of farms (95% CI: 79.8-99.3%). The average number of trapped mites among farms was 5200 ± 16,522, with a median of 359 mites (interquartile range = 46-3135). Results from the questionnaire show that insufficient monitoring, under-detection and late and suboptimal treatment may contribute to the maintenance of significant infestation levels. The present data highlight the need for adequate monitoring of , timely action and effective treatment in order to improve poultry productivity and ensure human and animal health and welfare. A survey on the prevalence of in Portuguese layer farms is presented The perceived importance of was assessed with a questionnaire was detected in 95.8% of farms The results emphasize the need for adequate monitoring and treatment optimization.
, 也被称为家禽红螨 (PRM), 是家禽和森林鸟类的血液寄生虫。这种螨虫在全球许多地区都有流行, 对蛋鸡业构成威胁, 同时直接威胁母鸡的健康和福利, 并作为疾病的传播媒介。此外, 被 袭击的人可能会患上 gamasoidosis。尽管在几个欧洲国家都有很高的流行率, 但关于葡萄牙 的流行病学信息却很少。本研究旨在评估葡萄牙产蛋农场的流行率和感染水平, 并评估生产者对 的看法和态度。在 2016 年 8 月至 2017 年 11 月期间进行了一项调查, 其中包括 NUTS2 地区 Centro 和 Norte 的 24 个农场。使用波纹纸板陷阱采集螨虫, 并使用由 COST 行动 FA1404 WG1 编制的欧洲 COREMI 问卷评估农民对 PRM 的看法和态度。在 95.8%的农场 (95%置信区间: 79.8-99.3%) 中检测到 。农场之间捕获的螨虫平均数量为 5200±16522, 中位数为 359 只 (四分位距 = 46-3135)。问卷结果表明, 监测不足、检测不足、治疗时间晚和治疗效果不佳可能导致感染水平显著维持。目前的数据强调需要对 进行适当监测、及时采取行动和进行有效治疗, 以提高家禽生产力, 确保人类和动物的健康和福利。本文介绍了葡萄牙层状农场 流行情况的调查评估了问卷中对 的重视程度在 95.8%的农场中检测到了 结果强调了进行充分监测和优化治疗的必要性。
