In the course of an epidemiological survey of Echinococcus multilocularis (Leuckart, 1863), causative agent of alveolar hydatid disease, the autopsy of 154 red foxes, Vulpes vulpes (L.), captured in the Department of Cantal between November 1984 and February 1985 disclosed 144 cases of intestinal helminthiases. Helminths consisted of cestodes and nematodes; no trematodes were found. Multiple infestations were very frequent. Cestoda recorded consisted of the following species: Mesocestoides litteratus (Batsch, 1786) (40 cases; 26%), Taenia crassiceps (Zeder, 1800) (36 cases, 24%), Echinococcus multilocularis Leuckart, 1863 (23 cases, 14.9%), Taenia polyacantha Leuckart, 1856 (17 cases, 11.4%), Amoebotaenia paradoxa (Rudolphi, 1802) (8 cases, 5.2%), and Taenia pisiformis (Bloch, 1780) (2 cases, 1.3%). The following Nematoda were recovered: Uncinaria stenocephala (Railliet, 1884) (90 cases, 58.4%), Toxocara canis (Werner, 1782) (79 cases, 51.3%), Toxascaris leonina (Linstow, 1902) (39 cases, 25.3%), Trichuris vulpis (Froelich, 1789) (25 cases, 16%), Pterygodermatites affinis (Jaegerskioeld, 1904) (6 cases, 4%), and undetermined Trichostrongylidae (4 cases, 2.7%). Hosts were not examined for Trichinella sp. The cartography of each helminthiase revealed propitious areas of maintenance of the parasite. Echinococcus multilocularis had a very limited distribution compared with other taeniid species with a near-identical life cycle. Unknown ecological factors may have an adverse effect on the free stage (egg) of the cestode. The nematode Pterygodermatites affinis is reported here for the first time in France.

SUMMARYA descriptive epidemiological survey was undertaken of the ascarid nematode Toxocara canis in 521 red foxes (vulpes, vulpes) during the period January 1986 to July 1990. Age–prevalence and age–intensity profiles show that worm are significantly higher in cubs than in subadult or adult foxes and higher in subadult than in adult foxes. variations in worm burdens occur, with the highest prevalences and intensities being found during the spring, when are born, and in the summer months. Prevalences and intensities then decrease during the autumn and winter months both subadult and adult foxes, but, during this period, prevalences are significantly higher in male than in female Variations in worm burdens in the fox population are likely to be related to the reproductive cycle of the fox, with proportion of cubs becoming infected in utero. The role of the fox in the transmission of T. canis in the urban environment is discussed.

AbstractDue to specific geographical localization, climatic and geomorphologic conditions, several serious parasitic diseases circulate in the territory of the Slovak Republic that makes this area an ideal model territory of the central European red fox system. The red fox is an important reservoir host of parasites, which can be spread to another animals and humans. Our study was aimed at determining the current prevalence of certain parasites in red foxes from the entire territory of the Slovak Republic and identifies some ecological factors influencing their epidemiology. Within the first systematic investigation of red foxes carried out between the years 2000 and 2006 in total 4026 foxes were examined for Echinococcus multilocularis (prevalence 31.1 %) and 4699 foxes were investigated for the presence of Trichinella spp. larvae (10.4 % infected). The results of the next separate study revealed that 83.3 % of 1198 red foxes in the Slovak Republic had coccidian oocysts and helminth eggs in their faeces. Fifteen helminth species including two trematode, four cestode and nine nematode species were detected by coprological examination. Nine of these parasite taxa have zoonotic potential: Capillaria spp. (prevalence 22.4 %), Ancylostoma caninum (18.1 %), Toxocara canis (12.5 %), Taenia spp. (12.2 %), Mesocestoides spp. (5.8 %), Strongyloides stercoralis (1.6 %), Hymenolepis diminuta (0.6 %), Dipylidium caninum (0.4 %) and Opisthorchis felineus (0.3 %). Toxascaris leonina was the most common helminth species found in this survey (42.9 %).

First Time

AbstractEchinococcus multilocularis was found for the first time in red foxes in the L’vivska and Volynska regions (Western Ukraine). Prevalence was 36% and intensity was 11–731 parasites. The material was identified as E. multilocularis on morphological characters. It is presumed that this infection of foxes with E. multilocularis occurred locally and, probably, can be considered as a consequence of the expansion of the range of the parasite.

SummaryA total of 180 foxes (Vulpes vulpes) from an area scarcely investigated of north-west Italy, were examined for intestinal helminths using sedimentation and counting technique (SCT). Faecal samples were submitted to centrifugation with 50 % zinc sulphate used as flotation solution.No fox was found completely negative for intestinal helminths. The most frequently identified nematodes were Uncinaria stenocephala (70.0 %), Molineus legerae (27.2 %), Toxocara canis (26.7 %), Toxascaris leonina (25.6 %), Trichuris vulpis (21.1 %), Aonchotheca putorii (8.9 %), Pterygodermatites affinis (5.6 %). Genus Mesocestoides (81.7 %), family Dilepididae (29.4 %) and Taenia spp. (8.3 %) were the most prevalent cestodes. All foxes were negative for E. multilocularis and E. granulosus. In two foxes trematodes belonging to the family Plagiorchidae were found.The study highlighted that foxes are hosts of intestinal helminths of veterinary and medical importance which may be transmitted to dogs and humans.

Abstract Background: The red fox (Vulpes vulpes) is a widely distributed animal in the world. This wild carnivore is also a common host of several dangerous zoonotic parasites, primarily nematodes. Nematodes of red foxes, such as Toxocara canis and Uncinaria stenocephala, can cause numerous health problems in humans and domesticated animals. The aim of the study was to determine the parameters of occurrence of nematodes in red fox (Vulpes vulpes) in north-western Poland. Methods: The study was carried out in north-western Poland. The research material consisted of 620 red foxes (Vulpes vulpes). Parasitological sections of the foxes were taken using the sedimentation and counting technique.Results: The prevalence of infestations with nematodes was 77.3%, while the mean infection intensity was 20.1 per animal. The presence of Toxocara canis, Toxascaris leonina, Uncinaria stenocephala and Trichuris vulpis was noted. The greatest prevalence was presented by Uncinaria stenocephala (34.0%). Male and female foxes displayed a similar prevalence of nematodes. Their presence was recorded in the duodenum, jejunum, ileum and caecum of the foxes, and they were significantly more common in the jejunum than in other parts. The most commonly-observed coinfection was between Uncinaria stenocephala and Toxocara canis. Conclusions: It can be seen that nematodes are present in high numbers among foxes in north-western Poland. This phenomenon certainly contributes to an increased risk of transmission of parasites to humans and domestic animals, and this can represent a threat to health and even life.

AbstractThe prevalence of Echinococcus multilocularis in 214 red foxes (Vulpes vulpes) in the southern part of Poland (Małopolskie voivodship) was evaluated post mortem in 2005. Infected foxes were found in 8 districts within 17 examined, with the prevalence from 10.0 % to 63.9 % (a mean 20.1 % in the whole study area). The highest prevalence (41.2 % and 63.9 %) was revealed in two districts, in the south and the east of the province, respectively. The high prevalence of E. multilocularis in red foxes in the region previously recognised as that of low parasite endemicity provides evidence for the need of regular screening of the current epidemiological situation in foxes as well as the monitoring of humans from risk groups for early recognition of possible AE cases.

Intestinal washes, faecal flotations and serological examinations for antibodies to Toxoplasma gondii and Neospora caninum were used to assess the prevalence of parasites in carcases of foxes killed on roads or shot in the Dublin area and surrounding counties. The ascarids Uncinaria stenocephala and Toxocara canis were prevalent, as was the trematode Alaria alata. Taenia species, eggs of Capillaria species and sporocysts of Sarcocystis species were also found. Only one fox out of 70 examined was seropositive for N caninum, whereas 24 of 51 were seropositive for Tgondii.

Knowledge about the dispersal and gene flow patterns in wild animals are important for our understanding of population ecology and the connectedness of populations. It is also important for management relating to disease control and the transmission of new and emerging diseases. Our study aimed to evaluate the genetic structuring among comparative samples of red foxes in a small part of Scandinavia and to estimate the gene flow and potential directionality in the movements of foxes using an optimized set of microsatellite markers. We compared genetic samples of red foxes (Vulpes vulpes) from two areas in Sweden and two areas in Norway, including red fox samples from areas where the occurrence of the cyclophyllic tapeworm Echinococcus multilocularis has been documented, and areas without known occurrence of the parasite. Our results show a high level of gene flow over considerable distances and substantiates migration from areas affected with E. multilocularis into Norway where the parasite is not yet detected. The results allow us to better understand the gene flow and directionality in the movement patterns of red foxes, which is important for wildlife management authorities regarding the spread of E. multilocularis.
