“…Few studies have been conducted on the health of freeliving MW, however, available reports include baseline hematology and chemistry profiles (Dietz, 1984;May-Júnior et al, 2009) cystinuria and cysteine calculi (Carvalho and vasconcellos, 1995;Deem and Emmons, 2005;Dietz, 1984), descriptions of endo-and ectoparasites (Beldomenico et al, 2002;Bevilaqua et al, 1993;Carvalho and vasconcellos, 1995;Deem and Emmons, 2005;Robbins and Deem, 2002), dental trauma (Furtado et al, 2007), and evidence of exposure to a number of infectious agents (Deem and Emmons, 2005;Deem et al, 2008). All diseases reported in free-living MW (except gunshot wounds and trauma caused by vehicle contact) are also commonly reported in captive MW, including some not yet identified in free-living individuals, such as dermatitis, proliferative gingivitis, neoplasia, and spondyloarthropathy (Fletcher et al, 1979;Hammond, 2012;Maia and Gouveia, 2002;Norton, 1990;Reid et al, 2005;Maned Wolf Husbandry Manual, 2007;Rothschild et al, 2001).…”

In his formal plan for the Institution, Joseph Henry outlined a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This theme of basic research has been adhered to through the years by thousands of titles issued in series publications under the Smithsonian imprint, commencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: In these series, the Institution publishes small papers and full-scale monographs that report on the research and collections of its various museums and bureaus. The Smithsonian Contributions Series are distributed via mailing lists to libraries, universities, and similar institutions throughout the world.Manuscripts submitted for series publication are received by the Smithsonian Institution Scholarly Press from authors with direct affiliation with the various Smithsonian museums or bureaus and are subject to peer review and review for compliance with manuscript preparation guidelines. General requirements for manuscript preparation are on the inside back cover of printed volumes.

Most data were collected by GPS-collar technology, which yielded over 37,000 locations in 27 collar deployments on 10 individuals. The eight chapters introduce the study area and methods (1) and describe daily and seasonal activity (2); movements and ranges (3); diet and energetics (4); social interactions and reproduction (5); disease exposure, morbidity and mortality (6); maned wolf conservation (7); and finally, we synthesize the results in an overview of maned wolf behavioral ecology, with hypotheses about the unique form and function of this atypical canid (8). Activity was temperature related and sharply nocturnal in the dry season but partly diurnal in the rainy season. Adult home ranges were 40-123 km 2 , with strong seasonal variations in land use. Maned wolves averaged 14 km/night travel in dry months and 7 km/night during wet months. Breeding pairs shared territories with contiguous borders, which did not overlap with neighboring pairs. Young females twice stayed until adulthood on natal territories, as presumed helpers, and a...

“…Studies on the parasites of free-ranging or recently captive maned wolves have documented the presence of the giant kidney worm, Dioctophyme renale, which is known to destroy the right kidney in infected maned wolves. 6 Parasites of the urinary tract, in addition to D. renale, 5 gastrointestinal parasites, 12 and ectoparasites 30 have also been documented in free-ranging maned wolves. In captivity, maned wolves are also known to be susceptible to Dirofilaria immitis, the causative agent of heartworm disease, Echinococcus granulosus, and gastrointestinal parasites.…”

Exposure of Free-Ranging Maned Wolves (Chrysocyon Brachyurus) to Infectious and Parasitic Disease Agents in the Noël Kempff Mercado National Park, Bolivia

Maned wolves (Chrysocyon brachyurus) are neotropic mammals, listed as a CITES Appendix II species, with a distribution south of the Amazon forest from Bolivia, through northern Argentina and Paraguay and into eastern Brazil and northern Uruguay. Primary threats to the survival of free-ranging maned wolves include habitat loss, road kills, and shooting by farmers. An additional threat to the conservation of maned wolves is the risk of morbidity and mortality due to infectious and parasitic diseases. Captive maned wolves are susceptible to, and die from, common infectious diseases of domestic dogs (Canis familiaris) including canine distemper virus (CDV), canine parvovirus (CPV), rabies virus, and canine adenovirus (CAV). Results from this study show that free-ranging maned wolves in a remote area of Bolivia have been exposed to multiple infectious and parasitic agents of domestic carnivores, including CAV, CDV, CPV, canine coronavirus, rabies virus, Leptospira interrogans spp., Toxoplasma gondii, and Dirofilaria immitis, and may be at increased risk for disease due to these agents.

“…The genus Capillaria was already described in crab-eating foxes and pampas foxes L. gymnocercus (Ruas et al 2003b) and in maned wolves (Vicente et al 1997) from Brazil. Capillariidae eggs were found in the urine of maned wolves from Argentina (Beldomenico et al 2002). Our results indicate that the maned wolf is more exposed to helminths than the crab-eating fox, with higher prevalence of Trichuridae and Ancylostomidae infection in SCNP (Table 3).…”

Wild canids, domestic dogs and their pathogens in Southeast Brazil: disease threats for canid conservation

et al. 2010

View full text Add to dashboard Cite

Wild canids are under many pressures, including habitat loss, fragmentation and disease. The current lack of information on the status of wildlife health may hamper conservation efforts in Brazil. In this paper, we examined the prevalence of canine pathogens in 21 free-ranging wild canids, comprising 12 Cerdocyon thous (crab-eating fox), 7 Chrysocyon brachyurus (maned wolf), 2 Lycalopex vetulus (hoary fox), and 70 nonvaccinated domestic dogs from the Serra do Cipó National Park area, Southeast Brazil. For wild canids, seroprevalence of antibodies to canine parvovirus, canine adenovirus, canine coronavirus and Toxoplasma gondii was 100 percent, respectively. Antibodies against canine distemper virus, Neospora caninum or Babesia spp. were not found. We tested domestic dogs for antibodies to canine parvovirus, canine distemper virus and Babesia spp., and seroprevalences were 59 (41/70), 66 (46/70), and 42 (40/70) percent, respectively, with significantly higher prevalence in domestic dogs for CDV (P \ 0.001) and Babesia spp. (P = 0.002), and in wild canids for CPV (P \ 0.001). We report for the first time evidence of exposure to canine coronavirus in wild hoary foxes, and Platynossomun sp. infection in wild maned wolves. Maned wolves are more exposed to helminths than crab-eating foxes, with a higher prevalence of Trichuridae and Ancylostomidae in the area. The most common ectoparasites were Amblyomma cajennense, A. tigrinum, and Pulex irritans. Such data is useful information on infectious diseases of Brazilian wild canids, revealing pathogens as a threat to wild canids in the area. Control measures are discussed.
