| seroprevalence of toxoplasma gondii antibodies from wild canids from brazil. | the prevalence of anti-toxoplasma gondii antibodies was evaluated by the indirect immunofluorescent-antibody test in serum of 57 wild canids from three different species: lycalopex gymnocercus, cerdocyon thous and dusicyon vetulus from the northeast, southeast and southern regions of brazil. the prevalence was 35.1%, with 20 of the 57 canids demonstrating antibodies anti-t. gondii at dilutions of 1:16 in 2, 1:32 in 4, 1:64 in 2, 1:128 in 2, 1:256 in 6, 1:512 in 2 and 1:2048 in 2 animals. none of ... | 2004 | 15135875 |
| parasites of free-ranging small canids and felids in the bolivian chaco. | parasite surveys of free-ranging wildlife provide important information for monitoring population health. between march 2001 and march 2003, we sampled 10 ocelots (leopardus pardalis), eight geoffroy's cats (oncifelis geoffroyi), a jaguarundi (herpailurus yaguarondi), five pampas foxes (pseudalopex gymnocercus), and three crab-eating foxes (cerdocyon thous) at three sites in the bolivian chaco. the objective of the study was to survey the parasite fauna of these carnivores and compare prevalence ... | 2006 | 17312790 |
| crab-eating fox (cerdocyon thous), a south american canid, as a definitive host for hammondia heydorni. | hammondia heydorni is a cyst forming coccidia closely related to other apicomplexans, such as toxoplasma gondii, neospora caninum and hammondia hammondi with a two-host life cycle. dogs and other canids as red foxes (vulpes vulpes) and coyotes (canis latrans) may serve as definitive hosts for h. heydorni. sporulated oocysts are infective for cattle, sheep and goats, which may serve as intermediate hosts. herein, we describe the ability of crab-eating fox (cerdocyon thous), a wild carnivore that ... | 2009 | 19303215 |
| [seroprevalence of antibodies anti-neospora caninum and anti-toxoplasma gondii in captive wild canids]. | neosporosis is considered one of the main cause of abortion in dairy cattle in the world. the prevalence of neospora caninum in wild species has been studied since the coyote (canis latrans), a north american wild canid specie was discovered as definitive host of this parasite. the aim of the present study was to determine the serum prevalence of n. caninum and t. gondii in wild native canids species from brazil. serum samples of 25 crab-eating dogs (cerdocyon thous), five pampas fox (lycalopex ... | 2008 | 20059860 |
| toxoplasma gondii and leishmania spp. infection in captive crab-eating foxes, cerdocyon thous (carnivora, canidae) from brazil. | the zoonoses toxoplasmosis and leishmaniasis are important worldwide and also affect wild animals. thus, the present study aimed to assess the prevalence of leishmania spp. and toxoplasma gondii antibodies in 52 serum samples from captive crab-eating foxes (cerdocyon thous) kept in 17 zoos in são paulo state, brazil. modified agglutination test (mat, for toxoplasmosis) and indirect fluorescent antibody test (ifat, for toxoplasmosis and leishmaniasis) were employed with heterologous anti-dog immu ... | 2010 | 20060648 |
| serologic survey of infectious diseases in populations of maned wolf (chrysocyon brachyurus) and crab-eating fox (cerdocyon thous) from aguas emendadas ecological station, brazil. | domestic dogs are reservoirs for many infectious diseases and may represent a potential source of infection for wild canid populations. a serologic investigation of antibodies to toxoplasma gondii, neospora caninum, brucella abortus, and leptospira spp. was conducted on three maned wolves (chrysocyon brachyurus) and seven crab-eating foxes (cerdocyon thous), all free-living, at the aguas emendadas ecological station (esecae), federal district, brazil, between february and october 2006. out of th ... | 2013 | 23505716 |
| first isolation and rflp genotyping of toxoplasma gondii from crab-eating fox (cerdocyon thous-linnaeus, 1766). | wild animals may play an important role in the transmission and maintenance of toxoplasma gondii in the environment. the purpose of the present study was to isolate and genotype t. gondii from a free-ranging crab-eating fox (cerdocyon thous-linnaeus, 1766). a crab-eating fox in critical health condition was attended in a veterinary hospital in recife, pernambuco state, brazil. the animal died despite emergency treatment. the brain was collected aseptically and destined for mouse bioassay. one is ... | 2017 | 28119049 |
| detection of antibodies to toxoplasma gondii in wild animals in brazil. | toxoplasmosis is a worldwide zoonosis caused by an obligate intracellular protozoan parasite, toxoplasma gondii, that affects all warm-blooded animals, including wild animals. the increased number of cases of parasitic infections is mainly due to the destruction of environmental conservation areas, which is driving wild animals out of their habitats and towards urban areas. in this study, the occurrence of t. gondii infection was investigated by the modified agglutination test (mat) in 26 differ ... | 2014 | 25278979 |
| genotyping of toxoplasma gondii and sarcocystis spp. in road-killed wild mammals from the central western region of the state of são paulo, brazil. | road-killed wild animals host zoonotic pathogens such as toxoplasma gondii, offering a new opportunity for the epidemiological study of these infectious organisms. | 2016 | 27812655 |
