Oral vaccination with bait is an effective method to prevent rabies in wildlife, but non-target wild animals may also ingest the bait vaccine. In Korea, the target animal of the rabies bait vaccine is the raccoon dog (Nyctereutes procyonoides). Bait vaccines have been distributed in Korea for 20 years; although wild raccoon dogs have been tested for antibodies, rabies antibodies have never been investigated in non-target wild animals. Therefore, this study investigated rabies antibody formation in wild boars (Sus scrofa), which is likely the main competitor for the bait vaccine in Korea. In bait areas, 20 of 109 wild boars (18.3%) were seropositive, and 39 of 470 wild boars (8.3%) in non-bait areas were also seropositive. These results provide insights regarding bait uptake or vaccination in non-target wild boars.

Abstract The aim of this study was to detect possible differences between farmed and wild-living raccoon dogs. Analysis of polymorphism in 15 microsatellite sequences led to the conclusion that raccoon dogs raised on Polish farms and wild raccoon dogs living in Poland are two genetically distinct groups of animals. Wild Polish raccoon dogs are genetically more similar to the population of wild animals from the Kaliningrad Region than to farmed animals. The analysis of microsatellite loci showed clear genetic differences between farmed and wild-living populations of raccoon dog, despite only 50 years of isolation of the two groups of animals. The farmed population was characterized by higher genetic variation than the wild-living population. On the basis of the analyses three microsatellite loci (INU014, Ren13J22 and Ren41D20) were proposed for determination of the origin of animals that have escaped from farms.

Abstract Background Anaplasma phagocytophilum is an obligate parasitic intracellular bacterium. It is the causative agent of granulocytic anaplasmosis, with effects on human and animal health. In Europe, the pathogen is mainly transmitted among a wide range of vertebrate hosts by blood-sucking arthropods. The aim of this study was to determine the presence of A. phagocytophilum in wild carnivores, viz raccoon dogs (Nyctereutes procyonoides), badgers (Meles meles), foxes (Vulpes vulpes), martens (Martes sp.) and European polecats (Mustela putorius), using molecular methods. Methods In the present study, 174 spleen samples were collected from adult, wild carnivores hunted in the years 2013–2016. A short fragment (383 bp) of the 16S ribosomal RNA gene partial sequence was used as a marker to identify A. phagocytophilum in spleen samples collected from carnivores using nested PCR. Results The prevalence of A. phagocytophilum in wild carnivores was 31.61% (55/174). Seven sequences of A. phagocytophilum were generated from two raccoon dogs, two badgers, one marten, one red fox and one European polecat. Six identical nucleotide sequences were obtained from one raccoon dog, two badgers, one marten, one red fox and one European polecat (A. phagocytophilum sequences 1: MH328205–MH328209, MH328211), and these were identical to many A. phagocytophilum sequences in the GenBank database (100% similarity). The second sequence (A. phagocytophilum sequence 2: MH328210) obtained from the raccoon dog shared 99.74% identity with A. phagocytophilum sequence 1. Conclusions To our knowledge, this is the first study to use molecular methods to determine the presence of A. phagocytophilum in wild carnivores, viz raccoon dog, badger, marten and European polecat, in Poland. The detected A. phagocytophilum sequences (1 and 2) were closely related with those of A. phagocytophilum occurring in a wide range of wild and domestic animals and vectors.

Abstract The aim of the study was to determine the relationship between age and temperament as well as reproductive results in female raccoon dogs. The study was carried out at two raccoon dog breeding farms located in south-eastern Poland. A total of 189 foundation stock females were evaluated for temperament using a modified behavioural empathy test. Animals were classified into five temperament groups: very fearful (VF), fearful (F), confident (C), aggressive (A) and very aggressive (VA). The animals with calm temperament (C) formed the largest group (49.9%) whereas the smallest number of animals was classified as VA (5.6%). The influence of age on the temperament of raccoon dog females and the number of young born and weaned (P≤0.01) was revealed. At the same time, temperament did not affect reproductive parameters (P>0.05). Summing up, the results of this study indicate lack of correlation between temperament and reproductive parameters. It can be assumed that the elimination of aggressive animals from the foundation stock will not compromise production results and can help to facilitate handling and improve animal welfare.

Chromosomes of a wild-caught male Korean raccoon dog (Nyctereutes procyonoides koreensis) were analyzed by conventional stain, G-banding and C-banding techniques. The basic karyotype of this subspecies is composed of metacentric (M) and acrocentric (A) chromosomes plus a variable number of B chromosomes (2n = 54 (= 10M + 42A + XY or XX) + Bs) and is the same as that of the Chinese and Finnish raccoon dogs (Nyctereutes procyonoides procyonoides). Karyotypes of the four subspecies of Nyctereutes procyonoides investigated to date conform to one of two types, the continental and the island. All animals from mainland Asia and eastern Europe that have been examined have the continental karyotype (2n = 54 (= 10M + 42A + XY or XX) + Bs), whereas all those from the four major Japanese islands that have been examined have the island type (2n = 38 (= 26M + 10A + XY or XX) + Bs). The two karyotypes have the same fundamental number (chromosomal arm number) of 66, and complete arm homology. However, the phylogenetic and taxonomic significance of the two distinct karyotypes within this monospecific genus is still unclear.Key words: raccoon dog, Nyctereutes, chromosomes, phylogeny, taxonomy.

Based on radio-tracking of Eurasian badgers ( Meles meles (L., 1758)), red foxes ( Vulpes vulpes (L., 1758)), and raccoon dogs ( Nyctereutes procyonoides (Gray, 1834)) and observations at burrows conducted in Białowieża Primeval Forest (eastern Poland) in 1996–2002, we addressed the hypothesis that facilitative interactions between a native (badger) and an alien (raccoon dog) species contributed to the invasion success of the latter. In winter, 88% of badger setts were occupied by both badgers and raccoon dogs, 4% by badgers and red foxes, and 4% by all three species. In summer, only 20% of badger setts were cohabited by other carnivore species (10% by raccoon dogs and 10% by foxes). Duration of occupation of badger setts by raccoon dogs averaged 117 days (SE = 21 days). Seasonal variation in raccoon dog use of badger setts was explained by changes in ambient temperature: the lower was the temperature, the higher was the rate of sett occupation by raccoon dogs. When wintering in the same sett, badgers and raccoon dogs used different parts of the sett. We conclude that facilitation by badgers (through habitat amelioration and refuge from cold and predation) makes the realized niche of raccoon dogs larger than predicted from their fundamental niche. The facilitating role of badger is stronger in winter, which is a critical period for raccoon dog survival in the temperate and boreal zone.

Samarskaya Luka

The raccoon dog, which is inhabit the territory of national park Samarskaya Luka, considered an invasive species with the high ecological plasticity. It has been acclimatized successfully and still continues to expand its range. Taking into account this fact, it is particularly relevant to reveal some aspects of its behavior. The important point is the adaptation of the species in the conditions of anthropogenic press, which are observed in the national parks territory. The studies was carried out on the riparian territories of the national park Samarskaya Luka (village Mordovo and village Malaya Ryazan), because the raccoon dog tends to inhabit the floodplain areas, river banks, islands and channels, and avoid large open fields. The research object is the raccoon dogs population on riparian territories of the national park. The study was carried out by detailed winter footprints tracking method. The article presents data on the weather's severity conditions, Bodman index was calculated for the areas of tracking in the study period. The data compared detailed winter tracking in the snowy (2012) and snowless (2013) research period materials are presented. The obtained data illustrate differences in research, food and food searching behavioral activity of raccoon dogs males and females depending on the depth of the snow cover and weather conditions. The results are consistent with the literature data on the weather's severity in the Samara region and changes of canids behaviors in different seasons. The data obtained can be used by staff of specially protected natural areas, forestry and hunting organizations for introduced species population monitoring.

Цель - проанализировать наличие меланина и оценить частоту встречаемости пигментированных шишковидных желёз (ШЖ) у псовых разных возрастных групп. Материал и методы. Объекты исследования - енотовидная собака (Nyctereutes procyonoides Grey), лисица (Vulpes vulpes L.) и песец (V. Lagopus L.). У неполовозрелых, или ювенильных (6-8 мес), и половозрелых (1,5-3,5 лет) самок животных каждого вида визуально оценивали наличие пигментации ШЖ и подсчитывали доли (%) пигментированных и непигментированных желёз. Число неполовозрелых и взрослых животных каждого вида было следующим: енотовидной собаки (n=4, n=15), лисицы (n=15, n=28) и песца (n=14, n=14 соответственно). Морфологические особенности ШЖ изучали гистологическими методами исследования, срезы окрашивали гематоксилином - эозином, а также по Массону-Фонтана. Результаты. В ШЖ исследованных видов обнаружены скопления пигмента меланина как на периферии железы, так и возле кровеносных сосудов. Визуально зафиксирована большая вариабельность пигментации желёз: от непигментированных до интенсивно пигментированных. На частоту встречаемости пигментированных желёз оказывали влияние возраст и видовая принадлежность. У енотовидных собак пигментированные эпифизы наблюдались только у неполовозрелых особей (25 %), у лисиц - только у взрослых (21,4 %). У песцов они были характерны для обеих возрастных групп, но с возрастом их доля снижалась (с 21,4 до 7,1 %). Выводы. Обнаружена широкая вариабельность степени пигментации ШЖ у псовых. Частота встречаемости пигментированных ШЖ характеризуется видоспецифичностью и зависит от возраста животных. Objective - to study the presence of melanin in the pineal gland (PG) and to assess the frequency of the pigmented glands occurrence in Canidae of different age groups. Material and methods. The objects of the research were raccoon dog (Nyctereutes procyonoides Grey), fox (Vulpes vulpes L.) and Arctic fox (V. lagopus L.). In immature (6-8 months) and adult (1,5-3,5 years) females of each species, the presence of the PG pigmentation was visually assessed and the proportion (%) of the pigmented and non-pigmented PG was calculated. The number of immature and adult animals was as follows: raccoon dog - n=4, n=15, fox - n=15, n=28, Arctic fox - n=14, n=14, accordingly. PG morphology was studied by histological methods; the sections were stained with hematoxylin and eosin and according to Masson-Fontana technique. Results. Clusters of melanin in the PG of studied species were located both on the periphery of the gland and near the blood vessels. The great variability of the PG pigmentation was detected. The age and the species membership affected the frequency of pigmented PGs findings. In raccoon dogs pigmented PGs were observed in immature individuals only (25 %), in foxes - in adults only (21,4 %). In blue foxes pigmented PGs were characteristic of both age groups, but with age their proportions decreased (from 21,4 to 7,1 %). Conclusions. A great variability in the degree of PG pigmentation was demonstrated. The frequency of the pigmented glands occurrence in Canidae is species-specific and depends on the age of the animals.

Abstract Human alveolar echinococcosis, caused by the larval stage of the small fox tapeworm, is a lethal zoonotic infection if left untreated. E. multilocularis is distributed in the Northern Hemisphere and lives in the small intestines of carnivores, mainly canids. The main definitive host of E. multilocularis in European countries is the red fox Vulpes vulpes and in the last ten years new endemic areas for the parasite in Central Europe have been identified. In some areas, for instance in Germany, the raccoon dog Nyctereutes procyonoides - a spreading neozoon - must be regarded as an additional definitive host for E. multilocularis. In 2001 this parasite was found for the first time in raccoon dogs in the Federal State of Brandenburg, Germany. Between 2000 and 2008, 1,252 raccoon dogs from Brandenburg were examined by the Intestinal Scraping Technique. The majority of samples were obtained in five northern counties and all 60 animals that tested positive for E. multilocularis were located there. The estimated true prevalence calculated by a beta-binomial- model ranged from 6%–12%.
