SUMMARY:

The environmental changes caused by the degradation of Brazilian biomes have been causing a great impact on wild animals, increasing the proximity of wild species with domestic animals and man, favoring the of parasitic and infectious diseases. The objective of the study was to identify the parasites found in wild free-living animals treated at a private veterinary clinic. Samples of feces, blood and ectoparasites were collected from wild animals from December 2019 to June 2020. For identification, coproparasitological and adult worms were collected at necropsy, blood smear for hemoparasites and collected ectoparasites. The sample group was 87 wild animals (58 birds and 29 mammals), corresponding to 34 different species of birds and four mammals. Of these animals, 44 (50.57%) showed positive results for parasitism (gastrointestinal or ectoparasite). Of the positives, 18 showed parasitism only by ectoparasites, 13 only by gastrointestinal parasites and 13 by both. Weaker animals showed greater infestation and parasitic infection than healthy animals. The ectoparasites birds were malophagous lice in baby birds of passerines and debilitated individuals (60%), flies of the of the genus Pseudolynchia sp. in predators (24%), and Amblyomma sp. on the eyelid of a Araçari-poca (Selenidera maculirostris) (4%). In mammals ticks of the genus Amblyomma sp. in Black-eared Opossums (Didelphis aurita), Graxaim (Cerdocyon thous) and Capybara (Hydrochoerus hydrachaeris). Two specimens of Black-eared Opossum and two of Graxaim showed puliciosis by Ctenocephalides felis, and a opossum was parasitized by a wild species of Siphonaptera (is in process of identification). Among birds, 53,3% had gastrointestinal infection by protozoa of de genus Eimeria and Isospora and 46,7% with nematode worms (Capillaria sp., Heterakis sp. and strongylids). In the group of mammals black-eared opossums present intestinal infection by Cruzia tentaculata, Ancylostoma sp. and Toxocara sp. Graxains showed parasitism by Ancylostoma sp. and Trichuris sp., capybara has negative results. Black-tuffed marmosets rescued in the peridomiciliary region (synanthropic) showed ascarid parasitism (Toxocara sp. And one to be identified), being potential transmitters of toxocariasis for domestic animals. Individuals of owl-devils (Asyo stygius) parasitized by Pseudolynchia sp. they, concomitantly, infection by Haemoprotheus sp., highlighting the importance of this fly as a vector in the transmission of hematozoa. A diversity of parasites in wild hosts is expected to find, because of the diversity of eating habits and environments in which they circulate. The presence of parasites of domestic hosts in wild animals indicates the proximity of these animals and the occurrence of cross contamination.
