Asticot maggot (Blowfly, Calliphoridae family) is the most important live bait used for angling in our country. Prevalence of allergy to live fish bait in occupationally exposed workers has been described. The purpose of this study was to determine the prevalence of asticot allergy in amateur fishermen and the identification of marketed asticot species in Cáceres, Spain.
Seventy-two randomised selected patients (Angler's Society of Cáceres) completed a questionnaire about fishing habits and allergic symptoms related with live bait handling. Skin prick test (SPT) with local asticot and common earthworm extracts were performed. Serum IgE levels to imported species (Protophormia terraenovae, Calliphora vomitoria, Lucilia sericata, Lumbricus terrestris) were measured. Local asticot and common earthworm samples were obtained for taxonomic identification. Data were analysed using the SPSS 12.0 software.
Five patients (7 %) reported allergic symptoms caused by asticot maggots. All of them were positive for SPT to asticot and specific IgE to P. terraenovae. Sensitisation to P. terraenovae was found in 40 patients (58.8 %). No associated factors for asticot allergy were observed. Larvae and adult flies of local asticot samples were identified as P. terraenovae.
Commercially available asticot, in Cáceres, is composed by P. terraenovae larvae (Diptera. Calliphoridae). A 7 % prevalence of P. terraenovae allergy in amateur fishermen of Cáceres was obtained. The allergenic potential of P. terraenovae seems to be greater than that of other blowflies and L. terrestris. The SPT with P. terraenovae extract is a very sensitive and specific technique in the diagnosis of live bait allergy in fishermen.
绿头苍蝇幼虫（丽蝇科）是我国用于垂钓的最重要的活饵。已有职业暴露工人对活鱼饵过敏患病率的相关描述。本研究旨在确定西班牙卡塞雷斯地区业余渔民中绿头苍蝇幼虫过敏的患病率，并鉴定市场上销售的绿头苍蝇幼虫种类。
随机选取72名患者（卡塞雷斯垂钓者协会成员），完成一份关于钓鱼习惯以及与处理活饵相关过敏症状的问卷。用当地绿头苍蝇幼虫和普通蚯蚓提取物进行皮肤点刺试验（SPT）。检测血清中针对进口物种（新陆原伏蝇、反吐丽蝇、丝光绿蝇、蚯蚓）的IgE水平。获取当地绿头苍蝇幼虫和普通蚯蚓样本进行分类鉴定。使用SPSS 12.0软件对数据进行分析。
5名患者（7%）报告有绿头苍蝇幼虫引起的过敏症状。他们对绿头苍蝇幼虫的SPT和对新陆原伏蝇的特异性IgE均呈阳性。40名患者（58.8%）对新陆原伏蝇致敏。未观察到绿头苍蝇幼虫过敏的相关因素。当地绿头苍蝇幼虫样本的幼虫和成虫被鉴定为新陆原伏蝇。
在卡塞雷斯地区，市场上销售的绿头苍蝇幼虫由新陆原伏蝇幼虫（双翅目，丽蝇科）组成。卡塞雷斯地区业余渔民中新陆原伏蝇过敏的患病率为7%。新陆原伏蝇的致敏潜力似乎大于其他丽蝇和蚯蚓。用新陆原伏蝇提取物进行SPT是诊断渔民活饵过敏的一种非常敏感和特异的技术。
