AbstractExtraintestinal nematodes of the red fox (Vulpes vulpes) are a wide group of parasites that infect wild and domestic carnivores and occasionally humans. Nematodes in the cardiopulmonary system, stomach, urinary apparatus and muscle tissue of 165 red foxes (Vulpes vulpes) from north-west Italy (Liguria and Piedmont) were investigated between 2009 and 2012. Of the cardiopulmonary nematodes, a high prevalence ofAngiostrongylus vasorumandEucoleus aerophilus(syn.Capillaria aerophila) was found, 78.2% and 41.8% respectively;Crenosoma vulpis(15.8%) andFilaroidesspp. (4.8%) were also found.Spirocerca lupi(23.5%),Aonchotheca putorii(syn.Capillaria putorii) (8.6%) andPhysalopteraspp. (2.5%) were detected in the stomach andPearsonema plica(syn.Capillaria plica) (56.8%) in the bladder.Eucoleus boehmi(syn.Capillaria boehmi)was also detected in the nasal cavities of one of the two foxes examined. A coprological examination revealed eggs ofE. aerophilus,A. putorii,S. lupi,Physalopteraspp. and eggs of intestinal parasites. Filarial worms were absent in all the 165 animals examined, nor was there evidence ofTrichinellaspp. in any of the foxes. The foxes were found to host a high prevalence of many species of extraintestinal nematodes. The prevalence ofA. vasorumin foxes found in the present study is among the highest in Europe. In addition, to the best of our knowledge,E. boehmiandFilaroidesspp. have never been reported before in this host in Italy.

AbstractIntroduction:The aim of the study was to determine the prevalence of respiratory capillariosis in red foxes (Vulpes vulpes) in some regions of Serbia.Material and Methods:The study was conducted on 102 foxes in six epizootiological regions of Serbia, during the hunting season between 2008 and 2012.Results:The presence of respiratory capillariosis in all tested epizootiological regions was confirmed. TheE. aerophilusnematode was detected with overall prevalence of 49.02%. The diagnosis ofE. aerophilusinfection was confirmed by the determination of morphological characteristics of adult parasites found at necropsy and the trichurid egg types collected from the bronchial lavage and the content of the intestine.Conclusion:The presented results contribute to better understanding of the epidemiology of this nematodosis in Serbia. However, the high prevalence of capillaries in tested foxes, demonstrated in all explored areas, might suggest that foxes from other regions in Serbia may also be infected. The fact that domestic carnivores and humans can also be infected enhances the importance of the overall epidemiological status. To establish the relevant prevalence of respiratory capillariosis, further investigations and continous monitoring of parasitic fauna of carnivores are needed in the whole country.

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.

AbstractSixty-eight red foxes were collected from the metropolitan area of Copenhagen and examined for helminth infections. Standard faecal flotations for intestinal parasites gave the following results: Strongyle eggs (75.0%), Capillaria eggs (36.8%), Toxocara eggs (23.5%), Taenia eggs (1.5%), and coccidia oocysts (2.9%). Gastrointestinal helminths were collected from 21 of the 68 foxes with the following specimens found: Uncinaria stenocephala (85.7%), Toxocara canis (81.0%), Taenia spp. (38.1%), Mesocestoides lineatus (23.8%) and Polymorphus spp. (9.5%). Faeces of 39 foxes were examined by the Baermann method for larvae of cardiopulmonary worms with 20 foxes (51.3%) being infected. Fourteen foxes (35.9%) were infected with Angiostrongylus vasorum, 11 (28.2%) were infected with Crenosoma vulpis, and 5 foxes (12.8%) were infected with both species. Muscle digestion of diaphragms from the 68 foxes indicated that none harboured larvae of Trichinella spiralis.

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.

AbstractPrevious studies have reported nematodes of the Spirocercidae family in the stomach nodules of red foxes (Vulpes vulpes) described asSpirocercasp. orSpirocerca lupi(Rudolphi, 1819). We characterized spirurid worms collected from red foxes and compared them toS. lupifrom domestic dogs by morphometric and phylogenetic analyses. Nematodes from red foxes differed fromS. lupiby the presence of six triangular teeth-like buccal capsule structures, which are absent in the latter. Additionally, in female worms from red foxes, the distance of the vulva opening to the anterior end and the ratio of the glandular-to-muscular oesophagus lengths were larger than those ofS. lupi(P< 0.006). In males, the lengths of the whole oesophagus and glandular part, the ratio of the glandular-to-muscular oesophagus and the comparison of the oesophagus to the total body length were smaller inS. lupi(allP< 0.044). Phylogenetic analyses revealed thatS. lupiand the red foxes spirurid represent monophyletic sister groups with pairwise nucleotide distances of 9.2 and 0.2% in the cytochrome oxidase 1 and 18S genes, respectively. Based on these comparisons, the nematodes from red foxes were considered to belong to a separate species, for which the nameSpirocerca vulpissp. nov. is proposed.

SUMMARYRed fox (Vulpes vulpes) is the most abundant wild canid species in Austria, and it is a well-known carrier of many pathogens of medical and veterinary concern. The main aim of the present study was to investigate the occurrence and diversity of protozoan, bacterial and filarial parasites transmitted by blood-feeding arthropods in a red fox population in western Austria. Blood (n= 351) and spleen (n= 506) samples from foxes were examined by PCR and sequencing and the following pathogens were identified:Babesia canis,Babesiacf.microti(syn.Theileria annae),Hepatozoon canis,Anaplasma phagocytophilum,CandidatusNeoehrlichia sp. andBartonella rochalimae. Blood was shown to be more suitable for detection ofBabesiacf.microti, whilst the spleen tissue was better for detection ofH. canisthan blood. Moreover, extremely low genetic variability ofH. canisand its relatively low prevalence rate observed in this study may suggest that the parasite has only recently been introduced in the sampled area. Furthermore, the data presented here demonstrates, for the first time, the possible vertical transmission ofH. canisfrom an infected vixen to the offspring, and this could explain the very high prevalence in areas considered free of its main tick vector(s).

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.

Aortic lesions pathognomonic for Spirocerca lupi were found in 123 of 150 (82%) coyotes. Canis latrans. 23 of 66 (35%) bobcats. Felis rufus, one of five gray foxes, Urocyon cinereoargenteus and one of two red foxes. Vulpes vulpes, examined in West Texas. Adult nematodes in the esophagus were recovered from 11 of 150 (7%) coyotes. In the aorta there was initially an acute inflammatory response followed by an eosinophilic granuloma surrounding larval nematodes. The principal lesion was scarring of the aorta with replacement of clastic tissue with collagen. There was blockage of the intervertebral arteries, pitting and formation of granulomatous nodules on the intimal surface and scarring with diverticula and aneurysms in affected animals. The response to adult nematodes in the esophagus was usually a small eosinophilic granuloma surrounding the worms. There was no evidence of esophageal sarcoma or spondylosis deformans of thoracic vertebrae as reported in the dog.
