“…However, we could not assert whether the maned wolves of the study area are natural hosts of this parasite or whether the infection is coming from sympatric domestic dogs and cats (exotics). The second alternative seems to be more likely as already suggested by Santos et al (2012). Dogs, domestic stray or errant, were commonly seen on a daily basis in the study area, where there is no efficient surveillance.…”

“…However, it is not easy to know whether parasitic infections represent a great harm to this species in Brazil, since few studies involving gastrointestinal parasites of C. brachyurus have been performed in nature (Dietz, 1984;Mattos et al, 2005;Braga et al, 2010;Curi et al, 2010Curi et al, , 2012Santos et al, 2012). It is also worth noting that these studies were performed in officially protected areas of the Brazilian savanna (Cerrado), the typical habitat of this species.…”

We examined 42 maned wolf scats in an unprotected and disturbed area of Cerrado in southeastern Brazil. We identified six helminth endoparasite taxa, being Phylum Acantocephala and Family Trichuridae the most prevalent. The high prevalence of the Family Ancylostomatidae indicates a possible transmission via domestic dogs, which are abundant in the study area. Nevertheless, our results indicate that the endoparasite species found are not different from those observed in protected or least disturbed areas, suggesting a high resilience of maned wolf and their parasites to human impacts, or a common scenario of disease transmission from domestic dogs to wild canid whether in protected or unprotected areas of southeastern Brazil.Keywords: Chrysocyon brachyurus, impacted area, parasites, scat analysis. Parasitas gastrointestinais de lobo-guará (Chrysocyon brachyurus,Illiger 1815) em uma área suburbana no sudeste do Brasil ResumoForam examinadas 42 fezes de lobo-guará em uma área desprotegida e perturbada do Cerrado no sudeste do Brasil. Nós identificamos seis táxons de helmintos endoparasitas, sendo o Filo Acantocephala e a Família Trichuridae os mais prevalentes. A alta prevalência da Família Ancylostomatidae indica uma possível transmissão por cães domésticos, que são abundantes na área de estudo. No entanto, nossos resultados indicam que as espécies de endoparasitas encontradas não são diferentes daquelas observadas em áreas protegidas ou menos perturbadas, o que sugere uma alta resiliência do lobo-guará e seus parasitas aos impactos humanos ou um cenário comum de transmissão de doenças de cães domésticos para um canídeo selvagem, seja em áreas protegidas ou desprotegidas do sudeste do Brasil.Palavras-chave: Chrysocyon brachyurus, área impactada, parasitas, análise fecal.

Risk factors for gastrointestinal parasite infections of dogs living around protected areas of the Atlantic Forest: implications for human and wildlife health

et al. 2016

Despite the ubiquity of domestic dogs, their role as zoonotic reservoirs and the large number of studies concerning parasites in urban dogs, rural areas in Brazil, especially those at the wildlife-domestic animal-human interface, have received little attention from scientists and public health managers. This paper reports a cross-sectional epidemiological survey of gastrointestinal parasites of rural dogs living in farms around Atlantic Forest fragments. Through standard parasitological methods (flotation and sedimentation), 13 parasite taxa (11 helminths and two protozoans) were found in feces samples from dogs. The most prevalent were the nematode Ancylostoma (47%) followed by Toxocara (18%) and Trichuris (8%). Other less prevalent (<2%) parasites found were Capillaria, Ascaridia, Spirocerca, Taeniidae, Acantocephala, Ascaris, Dipylidium caninum, Toxascaris, and the protozoans Cystoisospora and Eimeria. Mixed infections were found in 36% of samples, mostly by Ancylostoma and Toxocara. Previous deworming had no association with infections, meaning that this preventive measure is being incorrectly performed by owners. Regarding risk factors, dogs younger than one year were more likely to be infected with Toxocara, and purebred dogs with Trichuris. The number of cats in the households was positively associated with Trichuris infection, while male dogs and low body scores were associated with mixed infections. The lack of associations with dog free-ranging behavior and access to forest or villages indicates that infections are mostly acquired around the households. The results highlight the risk of zoonotic and wildlife parasite infections from dogs and the need for monitoring and controlling parasites of domestic animals in human-wildlife interface areas.Keywords: Canis familiaris, endoparasites, human-wildlife interface, zoonosis, protected areas.Fatores de risco para infecções parasitárias gastrointestinais em cães do entorno de áreas protegidas da Mata Atlântica: implicações para a saúde humana e da vida selvagem ResumoApesar da ubiquidade dos cães domésticos, de seu papel como reservatório de doenças, e do grande número de estudos sobre parasitas de cães urbanos, as áreas rurais no Brasil, especialmente aquelas na interface entre animais silvestres -animais domésticos -humanos, tem recebido pouca atenção de cientistas e gestores de saúde pública.

“…In the samples of a Cerdocyon thous (crab-eating fox) and Chrysocyon brachyurus (maned wolf ) were identified Cestoda eggs and Eimeria oocysts. In a study carried in wild canids of Serra do Cipó National Park, Brazil, revealed the presence of Ancylostomiae, Trichuridae eggs among others parasites in feces of Cerdocyon thous and Chrysocyon brachyuru, however, only one sample (20%) of Cerdocyon thous was found Cestoda eggs (SANTOS et al, 2012).…”

The objective of this study was to investigate the frequency of occurrence and variety of intestinal parasites among free-living wild animals. Fecal samples from wild mammals and birds at rehabilitation centers in the states of Mato Grosso do Sul and São Paulo were analyzed by sedimentation and flotation-centrifugation methods. Parasite eggs, oocysts, cysts and/or trophozoites were found in 71% of the samples. Cryptosporidium sp. oocysts were detected in fecal samples from oncillas (Leopardus tigrinus) and scaly-headed parrots (Pionus maximiliani). Giardia cysts were identified in the feces of a gray brocket (Mazama gouazoubira). Among the most common parasites found, there were eggs from Toxocara cati, Toxascaris leonina and Ancylostoma tubaeforme, and from Cestoda. Several Enterobius sp. eggs were found in the feces of red howler monkeys (Alouatta seniculus). It can be concluded from this study that despite the small number of samples, the diversity of parasites found was noteworthy. Additional information about parasite endofauna in wild animals is needed, since their presence might suggest that there could be proximity to and interactions with domestic animals and/or humans. In addition, further studies on parasites from free-living wild animals are of prime importance for understanding the intensity of anthropic changes in wild environments.
