SEROLOGICAL SURVEY OF TOXOPLASMA GONDII INFECTION IN NEOTROPICAL MAMMALS KEPT IN CAPTIVITY AT THE TRIAGE CENTER FOR WILD ANIMALS IN GOIÁS STATE, BRAZIL

Abstract

Toxoplasmosis is one of the most widespread and prevalent diseases worldwide, including among wild, free-living and captive animals. It is one of the most widely studied parasitic infections due to its medical and veterinary importance. In the State of Goiás, Central Brazil, there are not many reports on studies dealing with toxoplasmosis in animals, especially in wild animals. The current study aimed to look for the presence of anti-Toxoplasma gondii antibodies in some species of
tropical mammals kept in captivity in the Triage Center for Wild Animals in Goiás State (Centro de Triagem de Animais Silvestres do Estado de Goiás; CETAS-GO). For this purpose, blood samples were collected from 70 animals, adults and young, of both sexes, including: two oncillas (Leopardus tigrinus); one ocelot (Leopardus pardalis); one pampas cat (Leopardus colocolo); seven cougars (Puma concolor); 13 crab-eating foxes (Cerdocyon thous); one hoary fox (Lycalopex vetulus); seven coatis (Nasua nasua); one red-handed howler monkey (Alouatta belzebul); ten black
howler monkeys (Alouatta caraya); ten bearded capuchins (Cebus libidinosus); four black-tufted marmosets (Callithrix penicillata); one black bearded saki (Chiropotes satanas); six giant anteaters (Myrmecophaga tridactyla); two lesser anteaters (Tamandua tetradactyla) and four capybaras (Hydrochoerus hydrochaeris). Research for anti-Toxoplasma gondii antibodies was carried out by the modified agglutination test (MAT). Of the 70 neotropical mammals, only two individuals (2.8%)
tested positive, and these were one bearded capuchin (Cebus libidinosus) and one crab-eating fox (Cerdocyon thous). The titer found was 1/256 in the bearded capuchin (C. libidinosus) and 1/64 in the crab-eating fox (C. thous). The results highlight the importance of a deeper study of infection by T. gondii in neotropical mammals.
