“…Conversely, dogs and cats intruding or living near to forested environments may be found infested by wildlife-associated ectoparasites [12,28,50,321]. The exchange of ectoparasites between domestic and wild animals may also have implications from a conservational perspective, also because dogs may exchange endoparasites [324-326] and viruses [327,328] with wildlife species. For example, several wild canids (e.g., C. thous and P. gymnocercus ) and felids (e.g., Panthera onca , Puma concolor , Puma yagouaroundi , and Leopardus pardalis ) have been found harbouring parasites that may affect dogs and cats, including heminths (e.g., A. caninum , D. caninum , T. canis , and T. vulpis ) and protozoa (e.g., L. infantum ) [324-326,329-333].…”

Remarkably, while free-roaming wild canids infected with L. infantum are usually asymptomatic, captive ones seems to be more prone to develop clinical signs [329] and may even die from infection [332].…”

Dogs and cats in Brazil serve as primary hosts for a considerable number of parasites, which may affect their health and wellbeing. These may include endoparasites (e.g., protozoa, cestodes, trematodes, and nematodes) and ectoparasites (i.e., fleas, lice, mites, and ticks). While some dog and cat parasites are highly host-specific (e.g., Aelurostrongylus abstrusus and Felicola subrostratus for cats, and Angiostrongylus vasorum and Trichodectes canis for dogs), others may easily switch to other hosts, including humans. In fact, several dog and cat parasites (e.g., Toxoplasma gondii, Dipylidium caninum, Ancylostoma caninum, Strongyloides stercoralis, and Toxocara canis) are important not only from a veterinary perspective but also from a medical standpoint. In addition, some of them (e.g., Lynxacarus radovskyi on cats and Rangelia vitalii in dogs) are little known to most veterinary practitioners working in Brazil. This article is a compendium on dog and cat parasites in Brazil and a call for a One Health approach towards a better management of some of these parasites, which may potentially affect humans. Practical aspects related to the diagnosis, treatment, and control of parasitic diseases of dogs and cats in Brazil are discussed.

“…Wild carnivores such as dingoes ( Canis dingo ), golden jackals ( Canis aureus ), jaguars ( Panthera onca ), red foxes ( Vulpes vulpes ), and spotted hyenas ( Crocuta crocuta ) are wild natural reservoir hosts and thus essential for the maintenance of the parasite life cycle ( 72 , 74–77 ). Dipylidium caninum infections in crab-eating fox populations have been suggested as a possible consequence of anthropogenic expansion into the natural habitats of wild hosts ( 60 ). A study in the rural high-mountain region of Colombia reported the occurrence of D .…”

Neglected zoonotic helminthiases in wild canids: new insights from South America

et al. 2023

View full text Add to dashboard Cite

The global threat of neglected tropical diseases (NTDs) constitutes a public health issue in underdeveloped countries. Zoonotic helminthiases are the most common human NTD agents in developing countries in sub-Saharan Africa, Asia, and the Americas, causing a global burden of disease that exceeds that of more recognized infectious diseases such as malaria and tuberculosis. Wild canids are well-known mammals that act as natural reservoirs of zoonotic-relevant helminthiasis worldwide, thus playing a pivotal role in their epidemiology and transmission to humans. Here we evaluate the occurrence of zoonotic gastrointestinal helminths in two Neotropical wild canid species from the Amazonian and Andean regions of Colombia, i.e., the bush dog (Speothos venaticus) and the crab-eating fox (Cerdocyon thous). We recovered tapeworm proglottids from bush dog fecal samples and identified them molecularly as the canine-specific lineage of Dipylidium caninum by using cytochrome c oxidase subunit I (cox1) gene sequences. Moreover, examination of a crab-eating fox during necropsy revealed the presence of non-embryonated eggs of the neglected nematode Lagochilascaris cf. minor, in addition to eggs and gravid proglottids of the cestode Spirometra mansoni. These findings represent the first report of zoonotic-relevant cestodes, i.e., D. caninum (“canine genotype”), S. mansoni, and the nematode L. cf. minor, in bush dogs and crab-eating foxes as final hosts. The occurrence of these zoonotic helminthiases in wild canid species calls for regular monitoring programs to better understand the epidemiology and transmission routes of neglected dipylidiasis, lagochilascariosis, and sparganosis in South America.

Domestic dog health worsens with socio-economic deprivation of their home communities

Evaluating relationships between poverty and dog health, we find that dogs in poor communities are sicker and more likely to be infected with zoonotic pathogens . 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 Here, we compare several dog health indicators in three rural communities of Panama with different degrees of socio-economic deprivation. From a total of 78 individuals, we collected blood and fecal samples, and assessed their body condition. With the blood samples, we performed routine hematologic evaluation (complete blood counts) and measured cytokine levels (Interferon-γ and Interleukin-10) through enzyme-linked immunosorbent assays. With the fecal samples we diagnosed helminthiases. Dogs were also serologically tested for exposure to Trypanosoma cruzi and canine distemper virus, and molecular tests were done to assess T. cruzi infection status. We found significant differences between dog health measurements, pathogen prevalence, parasite richness, and economic status of the human communities where the dogs lived. We found dogs that were less healthy, more likely to be infected with zoonotic pathogens, and more likely to be seropositive to canine distemper virus in the communities with lower economic status. This study concludes that isolated communities of lower economic status in Panama may have less healthy dogs that could become major reservoirs in the transmission of diseases to humans and sympatric wildlife.
