The maned wolf (Chrysocyon brachyurus), an inhabitant of the Brazilian savanna, is considered the largest canid of South America and is classified as a near-threatened species by the International Union for Conservation of Nature (IUNC). The purpose of this study was to investigate the presence of antibodies against Toxoplasma gondii, -Neospora caninum, -Leishmania spp., and -Ehrlichia canis in free-ranging maned wolves in the northeastern region of the state of São Paulo, Brazil. Of the 17 serum samples tested by the indirect fluorescent antibody test (IFAT), 88.2% (15/17), 17.6% (3/17) and 52.9% (9/17) showed anti-T. gondii, -Leishmania spp., and -E. canis antibodies, respectively. None of the studied maned wolves tested positive for N. caninum antibodies. Our results indicated the exposure of free-ranging maned wolves to the agents in question. The presence of industrial complexes, extensive agriculture and habitat fragmentation in the northeastern region of the state of São Paulo puts these wild animals in proximity to urban areas, possibly contributing to the transmission of diseases between wild and domestic animals and human beings.
