摘要: Hepatozoon canis is a tick-borne parasite that occurs worldwide. In rural areas of Brazil, H. vectors remain unknown, which has led to speculation about alternative routes transmission. Small rodents can play role in the transmission (via predation) americanum, us question whether predation might be an mode for canis. Thus, this study investigated spp. are present wild small forest fragments surround Botucatu County, Sao Paulo, where canine hepatozoonosis endemic. The included blood samples from 158 dogs, were screened by microscopy and molecular analysis. Blood tissues 67 obtained histopathology detection. prevalence was high (66.45%) dogs Botucatu, Brazil. analysis showed rodent species Brazil infected with other than Therefore, although hypothesis sylvatic act as reservoirs not supported, presence monozoic cysts suggests that, addition intermediate hosts, paratenic hosts because they harbor infective stages host predators.
