UNASSIGNED: The study area covered three water bodies (Lake Skanda, Lake Ukiel, and Lake Tyrsko) over the summer of 2021. In total, 747 pulmonate freshwater snails (Radix spp., Lymnaea stagnalis) were collected. Each snail was subjected to 1-2 h of light stimulation to induce cercarial expulsion. The phylogenetic analyses of furcocercariae were based on the partial sequence of the ITS region (ITS1, 5.8S rDNA, ITS2 and 28SrDNA). For Radix spp. phylogenetic analyses were based on the ITS-2 region.
UNASSIGNED: The prevalence of the Trichobilharzia species infection in snails was 0.5%. Two out of 478 (0.4%) L. stagnaliswere found to be infected with Trichobilharzia szidati. Moreover, two out of 269 (0.7%) snails of the genus Radix were positive for schistosome cercariae. Both snails were identified as Radix auricularia. One of them was infected with Trichobilharzia franki and the other with Trichobilharzia sp.
UNASSIGNED: Molecular identification of avian schistosome species, both at the intermediate and definitive hosts level, constitutes an important source of information on a potential threat and prognosis of local swimmer\'s itch occurrence, and helps to determine species diversity in a particular area.
■研究区域覆盖了三个水体(Skanda湖,Ukiel湖,和Tyrsko湖)在2021年夏天。总的来说,747肺状淡水蜗牛(Radixspp。,收集了lymnaeastagnalis)。每个蜗牛都受到1-2小时的光刺激以诱导子囊排出。furcocer科的系统发育分析基于ITS区域的部分序列(ITS1,5.8SrDNA,ITS2和28SrDNA)。对于基数。系统发育分析基于ITS-2区域。
■蜗牛中毛虫属物种感染的患病率为0.5%。发现478个(0.4%)的stagnalisis中有2个感染了毛虫szidati。此外,269只(0.7%)蜗牛中的2只对血吸虫尾蚴呈阳性。两种蜗牛均被鉴定为黑木耳。其中一个感染了Trichobilharziafranki,另一个感染了Trichobilharziasp。
■禽血吸虫物种的分子鉴定,在中级和最终宿主级别,构成了当地游泳运动员瘙痒发生的潜在威胁和预后的重要信息来源,并有助于确定特定地区的物种多样性。
