Human cercarial dermatitis is a parasitic disease that causes an allergic reaction in the skin (swimmer’s itch) as a consequence of contact with cercariae of bird schistosomes present in water, mainly of the genus Trichobilharzia Skrjabin et Zakarow, 1920. The main objective of the study was to confirm the presence of the zoonotic disease agent following reports of human infections in recreational water in Slovakia. We identified two species of freshwater snails at Košice Lake, Radix auricularia (Linnaeus, 1758) and Physa acuta (Draparnaud, 1805). Trematode infections were observed only in R. auricularia. Of the 62 snails collected, 11 (17.7%) were infected with 5 different species of larval stages of trematodes. The blood fluke Trichobilharzia franki was found in 2 (3.2%) of the examined snails. The present record provides the first evidence that T. franki from the pulmonate snail R. auricularia represents a source of human cercarial dermatitis in recreational water in Slovakia. Our finding complements the easternmost records of both swimmer’s itch and the confirmed occurrence of a bird schistosome in a waterbody in Europe. The present work suggests that the health risks associated with trichobilharziasis need to be further studied by detailed monitoring of the occurrence of the major causative agent of human cercarial dermatitis, T. franki.

人类宫颈皮炎是一种寄生虫病，由于与水中存在的鸟血吸虫（主要是Trichobilharzia Skrjabin等，Zakarow属）的尾虫接触，会引起皮肤过敏反应（游泳者的瘙痒）。研究的主要目的据报道，有人在斯洛伐克的娱乐水中感染了人畜共患病病毒，以确认存在人畜共患病。我们在科希策湖中发现了两种淡水蜗牛，分别是大头参（Linix auricularia）（Linnaeus，1758年）和实（Physa acuta）（Draparnaud，1805年）。仅在耳廓罗非鱼中观察到吸虫感染。在收集的62只蜗牛中，有11种（17.7％）感染了5种不同种类的吸虫幼虫。吸血鬼在被检查的蜗牛中，有2只（3.2％）被发现为弗兰克氏菌。本记录提供了T的第一个证据。来自肺蜗牛的弗兰克（Rrank auricularia）代表了斯洛伐克娱乐水中人类宫颈性皮炎的来源。我们的发现补充了最东端的游泳者瘙痒记录以及在欧洲水域中证实的鸟类血吸虫病的发生。目前的工作表明，与沙眼衣原体有关的健康风险需要通过详细监测人类宫颈皮炎的主要病因T的发生来进一步研究。franki。
