Abstract This study investigated infection by Leishmania spp., Leptospira Toxoplasma gondii, and Trypanosoma cruzi in six-banded armadillos (Euphractus sexcinctus) from the semiarid region of northeastern Brazil. Twenty specimens E. sexcinctus were captured alive wildlife veterinarians their natural habitats different locations. The animals euthanized following induction anesthesia, biological samples collected. Infection with four pathogens was subsequently evaluated: spleen liver Polymerase Chain Reaction (PCR); spp. evaluated kidney PCR serologically microscopic agglutination test; T. gondii assessed heart, lung, spleen; heart whole blood hemoculture. All tests presented negative results apart to detect cruzi, which positive one 20 tested confirmed genetic sequencing. It is important highlight that this first comprising a molecular investigation zoonotic armadillos, findings reported here bring new knowledge regarding diseases species.

Leishmaniasis and toxoplasmosis are two of the most common parasitic zoonoses. is endemic to 98 countries around world, whereas widely distributed throughout causing significant health expenditure. Horses can play a relevant role in transmission disease, being silent reservoir, as clinical signs not common. Serum samples from 166 horses living eastern Spain (Mediterranean basin) were analysed determine presence antibodies against Leishmania spp. T. gondii by ELISA (Enzyme-linked Immunosorbent Assay.) The risk factors evaluated geographical area relative humidity average temperature, epidemiological such sex, reproductive status, age, breed, morphotype, with other domestic animals, use access outdoors. Seroprevalence infection was found 28.92%, 16.27% respectively, co-infection parasites only males. seroprevalence high castrated males several mesodolichomorphic equine breeds used for teaching, well outdoor animals. elevated winter higher levels rainfall, crossbreeding animals those breeding. High Mediterranean basin. These data suggest that act reservoir this species has potential humans, areas rainfall.
