“…The parasites pathogenic for dogs without zoonotic potential were also diagnosed in investigated dogs. Lungworms Angiostrongylus vasorum (1.7%) and Crenosoma vulpis (0.9%) were detected by larvoscopy testing, similar results were obtained in 2017 [25]. As lungworms in the dogs were rarely identi ed in the Czech Republic in the past, disease awareness of lungworms among animal owners and veterinarians should be implemented [30].…”

Background Endoparasites of the canine gastrointestinal and respiratory tract represent a wide range of protozoans and helminths. They are causative agents of different serious diseases of animals and many of them also pose zoonotic risks to human health. The education of dog owners and their families with the principles of human and animal health protection may especially prevent the spread of zoonoses such giardiosis, toxocarosis, echinococcosis and Taenia crassiceps infection. Pulmonary nematods are not zoonotic but they can cause serious and potentially fatal disease in dogs.MethodsThree hundred ninety-one samples of canine faeces and 398 completed questionnaires were collected. The questionnaires comprised of description of individual dogs and detailed data about the way the dogs were kept and their deworming. Samples were examined by flotation, larvoscopy by Baermann and PCR method.ResultsWe confirmed infection of Giardia spp., Isospora ohioensis, Neospora caninum/Hammondia heydorni, Ancylostoma spp., Angiostrongylus vasorum, Capillaria spp., Crenosoma vulpis, Toxocara canis, Toxascaris leonina, Trichuris spp. and Taenia spp. Sequences were obtained for 3 of them confirming T. crassiceps. No deworming treatment was recorded for insignificant number of dogs. Dog owners most often used multicomponent endoparasitics.ConclusionsMost of the dogs were dewormed irregularly and antiparasitics were administered namely twice a year, so monthly intervals were not performed in the group of dogs at risk for e.g. possibility of predation. Consumption of antiparasitic drugs cannot ensure the protection of dogs, their owners and other people, unless not applied purposefully, with appropriate knowledge and on the basis of the veterinarian's advice.

“…Switzerland was entirely included, with differing levels of predicted suitability (Morgan et al ., 2009). The spread of A. vasorum , as predicted by the model, has also been recently described from previously parasite-free areas (or areas with unknown presence) such as Romania (Deak et al ., 2017), Belgium (Jolly et al ., 2015), the Czech Republic (Hajnalová et al ., 2017), Slovakia (Hurnikova et al ., 2013) and even mainland North America (Priest et al ., 2018). Here we show that A. vasorum has successfully established in the Swiss fox population, reaching regional prevalences of more than 80%.…”

Angiostrongylus vasorum, Crenosoma vulpis and Capillaria aerophila are the most common lungworms of domestic and wild canids. We investigated the short- and long-term lungworm prevalence changes in the Swiss fox population with a focus on A. vasorum. Between 2012 and 2017, lungs and hearts of 533 foxes from north-eastern Switzerland were necropsied and blood samples tested for circulating A. vasorum antigen. Angiostrongylus vasorum prevalence increased steadily from 21.5% in 2012 to 81.8% in 2017. In contrast, C. aerophila and C. vulpis prevalences fluctuated between 41.8 and 74.7%, and 3.6 and 14.9%, respectively. Based on 3955 blood samples collected between 1986 and 2017 from three geographic areas and during four time periods, antigen seropositivity increased from 2.4 to 62.0%. In north-eastern Switzerland, seropositivity was initially low (1.9 and 1.7% in the first two time periods) but increased in the following two decades to 22.2 and 62.0%, respectively. Our findings depict the spectacular expansion of A. vasorum in the past three decades. Regionally, the prevalence in foxes increased 4-fold within 6 years in some regions. This underpins the important role of foxes as reservoir hosts, likely explaining the increasing number of cases of canine angiostrongylosis in Switzerland. Our findings are representative of central Europe and may help anticipating future developments in areas where A. vasorum is present but (still) infrequent.

“…Due to the unspecific clinical signs and difficulties in making a diagnosis, crenosomosis can be an important health issue for veterinary medicine (Cobb and Fisher, 1992;Rinaldi et al, 2007). Individual cases of the disease were recorded in domestic dogs (Cobb and Fisher, 1992;Reilly et al, 2000) and the prevalence of infection was estimated in some countries such as Germany (6.0%; Barutzki and Schaper, 2009), and the Czech Republic (2.0%; Hajnalová et al, 2018).…”

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.
