The flesh fly Sarcophaga carnaria is commonly used as fishing bait. Immunoglobulin (Ig) E-mediated reactions caused by the handling of this bait have been reported. The earthworm Dendrobaena species is increasingly being used as fishing bait but there have been no reported cases of allergy to this species to date. We studied a 26-year-old amateur angler who presented rhinoconjunctivitis, urticaria, and angioedema on handling S carnaria. He started to use Dendrobaena species instead but developed the same symptoms. The aim of this study was to identify the allergens involved in the patient's clinical reactions. The study was performed using immunoglobulin (Ig) E immunoblotting and immunoblotting inhibition assays.The patient's serum detected allergens from Dendrobaena species (of an apparent molecular weight of approximately 150, 60, 37, 24, 21 and 19 kDa) and S. carnaria (approximately 70 kDa and a smear ranging from 50 to 40 kDa). The patient was diagnosed with allergy to both Dendrobaena species and 5 carnaria. This is the first case describing Dendrobaena species as an allergic agent.
肉蝇 Sarcophaga carnaria 通常被用作鱼饵。已有报道称，因处理这种鱼饵而引起的免疫球蛋白（IgE）介导的反应。蚯蚓 Dendrobaena 物种越来越多地被用作鱼饵，但迄今为止尚未有对此种物质过敏的报道。我们研究了一位 26 岁的业余钓鱼者，他在处理 S carnaria 时出现鼻结膜炎、荨麻疹和血管性水肿。他开始改用 Dendrobaena 物种，但出现了同样的症状。本研究旨在确定参与患者临床反应的过敏原。使用免疫球蛋白（Ig）E 免疫印迹和免疫印迹抑制试验进行了研究。患者血清中检测到来自 Dendrobaena 物种（约 150、60、37、24、21 和 19 kDa）和 S. carnaria（约 70 kDa 和 50 至 40 kDa 的弥散带）的过敏原。该患者被诊断为对 Dendrobaena 物种和 5 carnaria 过敏。这是首例描述 Dendrobaena 物种为过敏原的病例。
