Abstract

Wild boars have a worldwide distribution and also have major economic, veterinary, and medical importance. Due to a small amount of data on the parasitic fauna of wild boars in the Russian Far East, especially in Prymorye territory, a post-mortem parasitic examination of 20 wild boars was provided. The general prevalence was 25%, and a total of six helminth species, including one larva stage, were found. The most prevalent helminth species were Gnathostoma doloresi (25%) and Metastrongylus elongatus (20%). Followed by Trichuris suis and Ascaris suum (15%). The lowest prevalence was registered for Cysticercus tenuicollis (the larvae stage of T. hydatigena). Parasites were found in each region, with the highest prevalence registered in the Chuguevskii region. Totally 100% of adult boars were positive for helminth infections, instead of 60% of young specimens. Some helminthes found (G. doloresi, T. suis, A. suum) have zoonotic potential and can be involved in the circulation of human parasitic diseases, especially in rural areas. Further research work on parasitic infections in wild boars in Prymorye is necessary due to the high prevalence of helminthes in wild boars.

俄罗斯滨海边疆区野猪的螺旋体感染

野猪分布于世界各地，在经济、兽医和医学方面具有重要意义。由于有关俄罗斯远东地区，尤其是普里莫利耶地区野猪寄生虫群的数据很少，因此我们对 20 头野猪进行了死后寄生虫检查。总体发病率为 25%，共发现六种蠕虫，包括一种幼虫。最常见的寄生虫种类是多发性钩端螺旋体（Gnathostoma doloresi）（25%）和长尾弓形虫（Metastrongylus elongatus）（20%）。其次是猪毛滴虫和蛔虫（15%）。囊尾蚴（T. hydatigena 的幼虫阶段）的感染率最低。每个地区都发现了寄生虫，其中丘古耶夫斯基（Chuguevskii）地区的寄生虫感染率最高。成年公猪的蠕虫感染率为 100%，而幼年公猪的感染率仅为 60%。发现的一些蠕虫（G. doloresi、T. suis、A. suum）具有人畜共患病的潜能，可能参与人类寄生虫病的传播，尤其是在农村地区。由于普里莫利耶野猪中蠕虫感染率很高，因此有必要对野猪的寄生虫感染开展进一步研究。

期刊介绍： The International Journal for Parasitology: Parasites and Wildlife (IJP-PAW) publishes the results of original research on parasites of all wildlife, invertebrate and vertebrate. This includes free-ranging, wild populations, as well as captive wildlife, semi-domesticated species (e.g. reindeer) and farmed populations of recently domesticated or wild-captured species (e.g. cultured fishes). Articles on all aspects of wildlife parasitology are welcomed including taxonomy, biodiversity and distribution, ecology and epidemiology, population biology and host-parasite relationships. The impact of parasites on the health and conservation of wildlife is seen as an important area covered by the journal especially the potential role of environmental factors, for example climate. Also important to the journal is ''one health'' and the nature of interactions between wildlife, people and domestic animals, including disease emergence and zoonoses.
