Serosurvey of antibodies against zoonotic pathogens in free-ranging wild canids (Cerdocyon thous and Lycalopex gymnocercus) from Southern Brazil

Absence of Leishmania spp. DNA in road-killed wild mammals in Southern Brazil

“…Leishmania DNA was not detected in M. gouazoubira and C. spinosus in the state of Paraná, Brazil ( Caldart et al, 2021 ) and in M. coypus in São Paulo ( Richini-Pereira et al, 2014 ) and antibodies against the agent was also not found in L. gymnocercus in Minas Gerais ( Curi et al, 2006 ) and Rio Grande do Sul ( Padilha et al, 2021 ), in Brazil. These results are similar to those of the present study for these species.…”

“…According to the literature, to date only two studies have been carried out in RS with the aim of detecting the presence of Leishmania spp. in land mammals: one involving C. thous ( Padilha et al, 2021 ) and another involving D. albiventris ( Soares, 2019 ). Both species are considered potential reservoirs of the protozoan ( Azami-Conesa et al, 2021 ; OPAS, 2021 ), however, marsupials stand out, as they can be infected without showing clinical signs of the disease and the fact that they keep the agent in their organism contributes to the maintenance of the parasite in the environment ( Azami-Conesa et al, 2021 ).…”

Padilha et al (2021) carried out a serological survey of antibodies against zoonotic pathogens such as L. infantum in free-ranging wild canids captured in the Pampa biome, including C. thous , but none of the animals sampled showed the presence of antibodies. Despite the use of different techniques, the results corroborate the present work.…”
