Angiostrongylus vasorum and Crenosoma vulpis infect the pulmonary arteries and airways, respectively, of red foxes (Vulpes vulpes). Both are widespread in Europe, but within North America, A. vasorum occurs only on the island of Newfoundland. During 2000–2002, 366 red fox carcasses were examined from six regions of Newfoundland for the purpose of determining the distribution of both parasites, effects on the condition of their host, and whether infection with one affects that of the other. Crenosoma vulpis occurred island-wide with a prevalence of 87% and mean (±SE) intensity of 230 ± 20.8. Young-of-the-year red foxes had more C. vulpis (260 ± 39.4) than yearlings (91 ± 31.2) or adults (78 ± 41.1) (χ2 = 25.72, df = 2, p < 0.001), and numbers of adult worm were weakly related to fecal output of first-stage larvae (r2 = 0.20, p < 0.001) but not to host sex or body-fat index. Angiostrongylus vasorum occurred only in southeast Newfoundland where prevalence was 56% and mean intensity was 72 ± 7.6. Its distribution may be limited by cold, as it was absent from areas with mean winter temperatures below –4 °C. Intensity of adult A. vasorum was not related to host age, sex, larval output, or measures of body condition. Although referred to as a heartworm, 88% of adult worms were actually found in the pulmonary arteries rather than in the right ventricle. Furthermore, there was no apparent association between infections with the two parasites (Gc[1] = 0.10) even though 40% of red foxes had dual infections.

The One

Among the wild canids, the red fox (Vulpes vulpes) is recognised as an important reservoir species for a range of parasites, including cardiopulmonary nematodes of public health and veterinary importance. As cross-host transmission between the red fox and domestic carnivores can play an important role in the epizootiology of cardiopulmonary parasitic diseases, the aim of the present investigations was to obtain data on the geographical distribution of cardiopulmonary nematodes of the red fox. The material for examination consisted of 83 foxes which were legally hunted at different locations during a three-month period from December 2017 to February 2018. The presence of four emerging species in Europe (Angiostrongylus vasorum, Crenosoma vulpis, Dirofilaria immitis and Eucoleus aerophilus) was revealed in red foxes of Serbia. Crenosoma vulpis and E. aerophilus were detected in foxes in both the plain and the mountainous areas across the country. Dirofilaria immitis is distributed in red foxes near alluvial rivers in Vojvodina province (northern Serbia). Angiostrongylosis caused by A. vasorum was demonstrated to exist in two enzootic foci with a high percentage of infected foxes in a plain area of northern Serbia. To the best of our knowledge, C. vulpis and A. vasorum were discovered for the first time in red foxes in central Serbia. The results provide strong evidence for veterinarians to take into consideration the parasitic nematodes discovered in red foxes in the differential diagnosis of diseases of companion animals. In the context of the ‘One Health’ approach the results related to the distribution of the zoonotic species E. aerophilus and D. immitis can be useful for medical epidemiology.
