Fleas (Insecta: Siphonaptera) are considered as highly specialized bloodsucking on mammals such as humans, livestock, dog, cat, rabbit, squirrels, rats, and mice. The desire for blood feeding from warm-blooded animals has led to becoming an intermediate host for some tapeworms like . The aim of this study was to detect larval infection in fleas of dogs living in Mesh-kinshahr County, northwest of Iran.
Fleas were collected from 42 dogs using brushing the hair in Meshkinshahr for one year (2014-2015). After the morphological study, fleas were preserved in 90% ethanol for molecular identification. After DNA extraction, the 28S ribosomal RNA gene (∼670 bp) of was amplified using specific primers. Finally, the PCR products were sequenced.
Overs, 974 fleas were collected from the dogs. In the morphological study, three species , and were identified. PCR and sequence analysis results showed that 4 isolates were infected with . Also, no positive specimens were isolated from the other two species.
is reported as the most important species of fleas in transferring in that region.
跳蚤（昆虫纲：蚤目）被认为是高度特化的以人类、家畜、狗、猫、兔子、松鼠、大鼠和小鼠等哺乳动物为宿主的吸血昆虫。对温血动物血液的吸食欲望导致其成为某些绦虫的中间宿主，如 。本研究的目的是检测生活在伊朗西北部Mesh-kinshahr县的狗身上跳蚤的 幼虫感染情况。
在Meshkinshahr通过梳理毛发从42只狗身上收集跳蚤，为期一年（2014 - 2015年）。经过形态学研究后，将跳蚤保存在90%乙醇中用于分子鉴定。提取DNA后，使用特异性引物扩增 的28S核糖体RNA基因（约670 bp）。最后，对PCR产物进行测序。
从狗身上共收集到974只跳蚤。在形态学研究中，鉴定出三种跳蚤，即 、 和 。PCR和序列分析结果显示，4个分离株感染了 。此外，从其他两个物种中未分离到阳性标本。
据报道， 在该地区是传播 最重要的跳蚤种类。
