We studied ectoparasites found on Canis lupus familiaris sampled in five areas in Mueang district, Khon Kaen Province, Thailand. The prevalence of fleas and ticks as well as their density were determined in 100 dogs that did not receive treatments. A total number of 458 ectoparasites was found corresponding to two species: 25.8% Ctenocephalides canis and 74.2% Rhipicephalus sanguineus. R. sanguineus was the most abundant species, and Ct. canis was the only flea species found. The stages of R. sanguineus were larvae (5.3%), nymphs (29.1%) and adults (39.1% in male and 26.5% in female). The stages of Ct. canis were larvae (41.5%) and adults (58.5%). Both species were commonly found on domestic dogs in all areas of the study. Ct. canis was not present on domestic dogs in one sub-district. The prevalence rates of tick-harboring domestic dogs was 80% (R. sanguineus), and flea-haboring domestic dogs was 26% (Ct. canis).
我们研究了在泰国孔敬府直辖县五个地区采集的家犬（Canis lupus familiaris）身上发现的体外寄生虫。在100只未接受过治疗的犬只中测定了跳蚤和蜱虫的感染率及其密度。共发现458只体外寄生虫，分属两个物种：犬栉首蚤（Ctenocephalides canis）占25.8%，血红扇头蜱（Rhipicephalus sanguineus）占74.2%。血红扇头蜱是数量最多的物种，犬栉首蚤是唯一发现的跳蚤物种。血红扇头蜱的各阶段包括幼虫（5.3%）、若虫（29.1%）和成虫（雄性占39.1%，雌性占26.5%）。犬栉首蚤的各阶段包括幼虫（41.5%）和成虫（58.5%）。在研究的所有地区，这两个物种在家犬身上都很常见。在一个分区的家犬身上未发现犬栉首蚤。携带蜱虫的家犬感染率为80%（血红扇头蜱），携带跳蚤的家犬感染率为26%（犬栉首蚤）。
