title: Hepatozoon spp.: report of some cases in dogs in Brasília, Brazil.
abstract: Canine hepatozoonosis is a disease caused by the tick-borne protozoan Hepatozoon spp. It has been reported in the United States, southern Europe, the Middle East, Africa and the Far East. In Brazil, canine hepatozoonosis is an emerging protozoal tick-borne disease, and is characterized by distinct clinical signs. The objective of this study was to analyze the laboratory findings of some hepatozoonosis cases in dogs in Brasília, Brazil, and their clinical signs. The animals of this experiment showed low parasitemia, similar to H. americanum, but the clinical signs presented were similar to H. canis. According to our observations and in agreement with O'Dwyer et al. [Vet. Parasitol. 94 (2001) 143], the Brazilian Hepatozoon appears more to resemble the species found in the eastern Hemisphere than with H. americanum of North America, or could be caused by a new species. Our data revealed that hepatozoonosis could be considered endemic in Brasília.
