Abstract

Great cormorants (Phalacrocorax carbo) are widespread piscivorous birds, which cause huge economic losses in the fish fauna worldwide. As a consequence of their predatory behaviour, they serve as definitive hosts for many digenean trematodes, and their digestive systems usually contain several parasite species. Between 2019 and 2022, 131 bird carcasses were collected from Biharugra (Hungary) as culling on the cormorant population. Their digestive systems were subjected to parasitological examination. The studied organs (131 intestines, 44 stomachs and 21 pharynxes) were opened, and their contents were settled in water, filtered, and sorted under microscope. For species identification, sequence analysis of the ITS region was performed. Of the 131 birds, 118 were infected by tapeworms or nematodes, 105 with trematodes, and 10 were parasite-free. The vast majority of obtained sequences (57 of the 105 trematodes) belonged to the genus Petasiger (43/57) and Hysteromorpha triloba (13/57). A single specimen of Metorchis sp. (1/57) as a zoonotic trematode was recorded during our survey. The results confirmed the high trematodes prevalence of the examined cormorants. However, most of them are not considered as human pathogens.

寄生在匈牙利大鸬鹚(Phalacrocorax carbo)消化系统中的地沟吸虫(吸虫纲:地沟吸虫纲)。
大鸬鹚(Phalacrocorax carbo)是一种分布广泛的食鱼鸟类,在世界范围内造成了巨大的经济损失。由于它们的掠食性行为,它们是许多地沟虫吸虫的最终宿主,它们的消化系统通常含有几种寄生虫。2019年至2022年期间,在比哈鲁格拉(匈牙利)收集了131具鸟类尸体,作为对鸬鹚种群的扑杀。对其消化系统进行了寄生虫学检查。打开所研究的脏器(131个肠、44个胃、21个咽),将其内容物沉淀于水中,在显微镜下过滤、分类。为了进行物种鉴定,对ITS区域进行了序列分析。其中绦虫、线虫感染118只,吸虫感染105只,无寄生虫感染10只。105个吸虫中有57个属于Petasiger属(43/57)和Hysteromorpha triloba属(13/57)。在调查过程中,我们记录到一株Metorchis sp.(1/57)作为人畜共患吸虫。结果证实,被检查的鸬鹚的吸虫率很高。然而,它们中的大多数不被认为是人类病原体。

期刊介绍: Helminthologia (HELMIN), published continuously since 1959, is the only journal in Europe that encompasses the individual and collaborative efforts of scientists working on a different topics of human, veterinary and plant helminthology. The journal responsibility is to enrich the theoretical and practical knowledge in very specific areas and thus contribute to the advancements in human and veterinary medicine and agronomy. Taking the advantage of comprehensive and multidisciplinary approaches journal still maintains its original spirit and is principal source of fresh scientific information regarding helminths, endoparasites and plant parasites. Addressing the most up-to date topics journal gained rightful and exceptional place next to the other high-quality scientific journals publishing in its field.
