Infections with zoonotic pathogens have received increasing attention in recent years, as reflected in the literature of both veterinary and human medicine. and are recognised as the principal causes of waterborne outbreaks worldwide, but there is still limited data on the role of wild carnivores, such as red foxes and wolves, as reservoir hosts and in disseminating these pathogens in the environment. The aim of the current project was to analyse the prevalence and abundance of and infections in foxes from seven voivodeships and in wolves from the Warmia-Masuria Voivodeship in Poland and to conduct a phylogenetic analysis of the detected parasites. For the detection of both parasites, we used the commercial immunofluorescent assay MeriFluor /. For detection we also applied modified Ziehl-Neelsen (ZN) staining of faecal smears and, following PCR amplification, sequenced the rDNA locus. For detection, we sequenced the glutamate dehydrogenase () gene. In total, 117 and 69 faecal samples obtained from red foxes and wolves, respectively, were screened for the presence of /. In red foxes, prevalence was 38.5% and 15.4% for spp. and , respectively. In wolves, the prevalence of spp. was 14.5%, and only one sample was -positive. , sp. vole genotype, and sp. were identified in red foxes, while and sp. were detected in wolves. Our results indicate that red foxes and grey wolves act as reservoir hosts of spp. and in natural areas in Poland.
近年来,人畜共患病原体感染受到了越来越多的关注,这在兽医和人类医学文献中均有体现。[具体病原体1]和[具体病原体2]被认为是全球水源性疾病暴发的主要原因,但关于野生食肉动物(如赤狐和狼)作为储存宿主以及在环境中传播这些病原体方面的作用,数据仍然有限。当前项目的目的是分析波兰七个省的狐狸以及瓦尔米亚-马祖里省的狼中[具体病原体1]和[具体病原体2]感染的流行情况和丰度,并对检测到的寄生虫进行系统发育分析。为了检测这两种寄生虫,我们使用了商业免疫荧光检测试剂盒MeriFluor /[具体检测内容]。对于[具体病原体1]的检测,我们还对粪便涂片进行了改良齐尔-尼尔森(ZN)染色,并在PCR扩增后对[具体病原体1]的rDNA位点进行测序。对于[具体病原体2]的检测,我们对谷氨酸脱氢酶([具体酶名称])基因进行了测序。总共分别从赤狐和狼中获取了117份和69份粪便样本,用于筛查[具体病原体1]和[具体病原体2]的存在情况。在赤狐中,[具体病原体1]属和[具体病原体1]的感染率分别为38.5%和15.4%。在狼中,[具体病原体1]属的感染率为14.5%,只有一个样本为[具体病原体2]阳性。在赤狐中鉴定出了[具体病原体1]、田鼠基因型[具体病原体1]、[具体病原体3]和[具体病原体4],而在狼中检测到了[具体病原体3]和[具体病原体5]。我们的结果表明,在波兰的自然区域,赤狐和灰狼是[具体病原体1]属和[具体病原体2]的储存宿主。
