摘要

Purpose The study aims to characterise and compare the helminth assemblages and helminth infracommunities in the marsh frog, Pelophylax ridibundus and the edible frog, P. esculentus collected in the northern part of Ukraine. Methods Occurrence and abundance of the helminths were analysed by calculating the prevalence, intensity, and mean abundance of infection; similarities between the infracommunities were estimated by the Bray-Curtis index and visualised using nMDS plots. Dissimilarities were estimated using the ANOSIM and SIMPER routines. Results In total, 27 helminth species were found in 143 frogs. Pelophylax ridibundus (n = 86) harboured 20 species of helminths, 24 species were found in P. esculentus (n = 57), and 17 species were shared by the two hosts. Oswaldocruzia bialata and larval Strigea sp. were absent in P. ridibundus, while they reached the prevalence of 30% and 10%, respectively, in P. esculentus. Cosmocerca ornata, Diplodiscus subclavatus, Opisthioglyphe ranae, and Codonocephalus urniger had significantly larger prevalence in P. ridibundus, whereas Haematoloechus asper was found to be more prevalent in P. esculentus. Acanthocephalus ranae, Icosiella neglecta, Haematoloechus variegatus, Pleurogenes claviger, Pleurogenoides medians, and Prosotocus confusus were equally common in both hosts. Helminth infracommunities in the two hosts had identical species richness (1-10 species, 4 on average); abundance was significantly higher in P. ridibundus. Conclusions Helminth assemblages of the two hosts in northern Ukraine are rather similar; however, small but significant differences were found in their species composition, parameters of infection in some species, and structure of helminth infracommunities.

Ecculentus收集在乌克兰北部。方法通过计算感染的患病率，强度和平均丰度来分析蠕虫的发生和丰度; Bray-Curtis指数估算了互通的相似性，并使用NMDS图可视化。使用Anosim和Simper惯例估算异化。结果总共有27种蠕虫物种。 Pelophylax Ridibundus（n = 86）哈密宫20种蠕虫，在P. esculentus（n = 57）中发现了24种物种，并由两个宿主共享17种。奥斯沃尔杜济岛Bialata和Larval Strigea sp。在P. Ridibundus中缺席，而他们分别在P.Sceculentus分别达到30％和10％的患病率。 Cosmocerca ornata，Opidiscus Subclavatus，Opisthioglyphe Ranae和Codonocephalus Urniger在P.Invibundus中具有显着更大的普遍性，而Praematoechus asper被发现在p. esculentus中更普遍。 acanthocephalus ranae，icosiella疏忽，血醇血清variegatus，pleurogenes claviger，pleurogenoides中等中间和varotocus combusus在两个宿主中同样常见。两家主持人的赫尔蒙特互通等物种丰富相同（1-10种，平均4种）; P. Ridibundus的丰度显着高。结论乌克兰北部两家主持人的Helminth集会相当相似;然而，在它们的物种组成中发现了小但显着的差异，在某些物种中的感染参数以及蠕虫互动的结构。
