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%).
跳蚤和蜱虫在吸食犬类血液时会传播各种病原体。本研究旨在核实巴西米纳斯吉拉斯州茹伊斯迪福拉市两个城区犬类身上体外寄生虫病和血液寄生虫病的发生情况。2003年2月至8月期间，对101只犬进行了研究：50只来自市中心区域的公寓，51只来自带有草地院子的房屋。体外寄生虫被采集并保存在70%乙醇中。通过检查从犬耳部采集的血涂片来核实血液寄生虫的存在。血涂片用吉姆萨染色，每张涂片检查100个视野，研究红细胞以确定是否存在寄生虫。在居住在公寓的犬中，我们发现（分别为患病率和平均感染强度）：猫栉首蚤（12%），（3.3±2.0）；血红扇头蜱（2%）；以及硬蜱若虫（2%）。在这种环境下，未在犬身上发现血液寄生虫。在带有草地院子的房屋中的犬身上，我们观察到以下患病率水平和平均感染强度：猫栉首蚤（14%），（2.28±1.9）；血红扇头蜱（35%），（7.8±9.8）；硬蜱若虫（18%），（1.4±0.7）；以及硬蜱幼虫（4%），（12±14.4）。发现的血液寄生虫有：犬埃立克体（16%）和犬巴贝斯虫（2%）。
