Медный (Командорские острова). В связи с резкой депрессией уникальной популяции медновского (командорского) песца – единственного хищника острова Медный и важного элемента местной экосистемы сохранение данного подвида является актуальной задачей для исследователей. Паразитарные болезни широко распространены у песцов, и исследователи рассматривают гельминтозы песца, как один из возможных лимитирующих факторов депрессии популяции. В связи с этим, целью нашего исследования стал паразитологический анализ органов и тканей, а также анализ патоморфологических изменений, повлекших за собой смерть животного. Работа проводилась на кафедрах патологической анатомии и судебной ветеринарной медицины, патологической физиологии и паразитологии им. В.Л. Якимова ФГБОУ ВО СПбГУВМ. При патологоанатомическом вскрытии трупа животного обнаружены признаки алиментарной дистрофии, а также острый катаральноэрозивный гастрит с кровотечением в полость желудка. По результатам паразитологического исследования в опухолевидной гранулеме стенки желудка и в его полости было обнаружено 11 взрослых особей нематод красного цвета, длиной 40–60 мм. Морфологические данные и локализация нематод дали основание идентифицировать их до р. Spirocerca. Ранее о находках гельминтов р. Spirocerca у песцов о. Медный не сообщалось.</p></abstract><trans-abstract xml:lang="en"><p>The article presents the results of the pathological examination of the corpse of an arctic fox delivered from Copper Island (Commander Islands). Due to the sharp depression of the unique population of the Mednovsky (commander) Arctic fox – the only predator of Medny Island and the key element of the local ecosystem, the preservation of this subspecies is an urgent task for researchers. Parasitic diseases are widespread in arctic foxes and researchers consider arctic fox helminthiasis as one of the possible limiting factors in population depression. In this connection, the purpose of our study was to analyze pathological changes in organs and tissues, including parasitological research, which entailed the cause of death of the animal. The work was carried out at the departments of pathological anatomy and forensic veterinary medicine, pathological physiology and parasitology named after V.L. Yakimov FSBEI HE SPbGUVM. According to the results of the postmortem autopsy of the animal, signs of alimentary dystrophy, as well as acute catarrhal erosive gastritis with hemorrhage to the stomach cavity were found. According to the results of parasitological research, 11 adult nematodes of red color, 40–60 mm long, were found in the tumor-like granuloma of the gastric wall and in its cavity. Morphological data and localization of nematodes gave reason to identify them up to the river. Spirocerca. Previously, about the finds of helminths p. Spirocerca in arctic foxes Copper Island did not communicate.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>песец</kwd><kwd>остров Медный</kwd><kwd>некропсия</kwd><kwd>желудок</kwd><kwd>спироцерка</kwd><kwd>морфология</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Arctic fox</kwd><kwd>Medny Island</kwd><kwd>necropsy</kwd><kwd>gastric</kwd><kwd>spirocercus</kwd><kwd>morphology</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Гольцман, М.Е.
