The neozoan species raccoon dog (Nyctereutes procyonoides) and raccoon (Procyon lotor) are widespread in Europe and potential vectors of many diseases that can threaten human and domestic animal health. Facing a further spread of these species, it is important to know about (i) pathogens imported and/or (ii) pathogens acquired in the new habitat. Thus, we investigated the parasite fauna of wild raccoon dogs and raccoons from Austria, at the edge of their new distribution range. The eight examined raccoons were nearly free of pathogens including Baylisascaris procyonis, and thus assumed to have a low epidemiological impact, so far. Out of ten raccoon dog specimens, we found one from western Austria to be infected with Echinococcus multilocularis and another three from the eastern wetland regions to harbour adults of Alaria alata. Furthermore, we detected Babesia cf. microti in five of eight raccoon dogs all over Austria but none of our samples were tested positive for Trichinella spp. Nevertheless, the raccoon dog seems to be a relevant host, at least for the zoonotic pathogens E. multilocularis and A. alata, and we suggest to further monitor the raccoon dogs parasite fauna.
新物种貉（Nyctereutes procyonoides）和浣熊（Procyon lotor）在欧洲广泛分布，是许多可能威胁人类和家畜健康的疾病的潜在传播媒介。面对这些物种的进一步扩散，了解（i）引入的病原体和/或（ii）在新栖息地获得的病原体非常重要。因此，我们调查了来自奥地利、处于其新分布范围边缘的野生貉和浣熊的寄生虫群落。所检查的八只浣熊几乎没有包括浣熊贝蛔虫在内的病原体，因此目前认为其流行病学影响较低。在十只貉标本中，我们发现来自奥地利西部的一只感染了多房棘球绦虫，另外三只来自东部湿地地区的貉体内寄生有翼状棘口吸虫成虫。此外，我们在奥地利各地的八只貉中有五只检测到微小巴贝斯虫，但我们的样本中没有旋毛虫属检测呈阳性。尽管如此，貉似乎是至少对于人畜共患病原体多房棘球绦虫和翼状棘口吸虫而言的相关宿主，我们建议进一步监测貉的寄生虫群落。
