在本研究中，我们确定了红狐的体外寄生虫社区在三个地区的波兰，其中包括两个地方性地区的发生ofDermacentor reticulatus，以及一个地区，是免费的这种蜱物种（“间隙”区）。我们的研究地点的选择，使狐狸作为主机的作用，少年（巢居）和成人（嗜外）D。确定网状蜱，并评估它们对这一重要媒介犬巴贝虫传播的贡献。我们还比较了成年狐狸与狐狸幼崽之间的体外寄生虫群落。最后，我们对皮下蜱进行了系统的搜索，以确定其流行率和丰度。2016-2018年，对366只成年狐狸和25只活捕幼狐进行了体外寄生虫检查。根据形态特征、PCR扩增和测序鉴定体外寄生虫。体外寄生虫的总患病率在幼崽（68%）高于成人（62.8%）。在成虫中，记录了15种寄生虫，包括4种蜱，7种蚤，疥疮，以及在Felicola和Lipoptena属中各有一种按蚊。在幼崽中，发现了6种体外寄生虫，包括在成虫中未发现的Ixodes kaiseri。蓖麻硬蜱和D.网纹蜱是成年狐体表的优势蜱种，非D.在幼崽身上发现了网状蜱。在所有地区，皮下蜱都很常见（38%），数量很多。皮下结节的分子分析允许17 I的鉴定。ricinus和fiveD.网状的总之，赤狐作为D.网状的
In the present study, we identified the ectoparasite communities of red foxes in three regions of Poland that encompassed two endemic regions for the occurrence ofDermacentor reticulatus, as well as a region that is free of this tick species ('gap' area). Our study sites were selected to enable the role of foxes as hosts for juvenile (nest dwelling) and adult (exophilic)D. reticulatusticks to be determined, and to assess their contribution to the spread of this important vector ofBabesia canis. We compared also ectoparasite communities between adult foxes with those of fox cubs. Finally, we carried out a systematic search for subcutaneous ticks determining their prevalence and abundance. In 2016-2018, 366 adult foxes and 25 live-trapped cubs were examined for ectoparasites. Ectoparasites were identified based on morphological features, PCR amplification and sequencing. The total prevalence of ectoparasites was higher in cubs (68%) than in adults (62.8%). In adults, 15 parasite species were recorded, including four tick species, seven flea species, scabies, and one Anopluran species each in the generaFelicolaandLipoptena.In cubs, six ectoparasite species were found, includingIxodes kaiseri, a species not found in adults. AlthoughIxodes ricinusandD. reticulatuswere the dominant tick species on adult foxes, noD. reticulatusticks were found on cubs. Subcutaneous ticks were common (38%) and abundant in all areas. Molecular analysis of subcutaneous nodules allowed the identification of 17I. ricinusand fiveD. reticulatus. In conclusion, red foxes play a minor role as hosts ofD. reticulatus.
