[Evaluation of ectoparasites and hemoparasites in dogs kept in apartments and houses with yards in the city of Juiz de Fora, Minas Gerais, Brazil].
Fleas and ticks transmit various pathogens while feeding on the blood of dogs. This study sought to verify the occurrence of ectoparasitism and hemoparasitism in dogs from two urban areas in the city of Juiz de Fora, Minas Gerais, Brazil. Between February and August 2003, 101 dogs were studied: 50 came from apartments in the downtown region and 51 from houses with grassy yards. The ectoparasites were collected and conserved in etanol 70%. The occurrence of hemoparasites was verified by examining blood smears from sample taken from the dogs'ears. The blood smears were stained with Giemsa and 100 fields per slide were examined, studying the erythrocytes to determine parasitism. From among the dogs living in apartments, we found (with respective prevalence and mean intensity): Ctenocephalides felis (12%), (3.3+/-2.0); Rhipicephalus sanguineus (2%); and ixodid nymphs (2%). In this environment in the dogs were not found hemoparasites. From the houses with grassy yards, we observed the following prevalence levels and mean intensities: C. felis (14%), (2.28+/-1.9); R. sanguineus (35%), (7.8+/-9.8); ixodid nymph (18%), (1.4+/-0.7); and ixodid larvae (4%), (12+/-14.4). The hemoparasites found were: Ehrlichia canis (16%) and Babesia canis (2%).
