The red fox (Vulpes vulpes) is widely distributed in the Northern Hemisphere and Australia. The presence of nematode-infected foxes in urbanized areas increases the risk of transmission of nematodes to domestic dogs and thus, to humans. The aim of this study was to determine the prevalence and species composition of intestinal nematodiasis in red foxes in Western Pomerania, a province in north-western Poland. The intestinal contents of 620 red foxes killed during a government reduction shooting programme were examined for adult nematodes using the sedimentation and counting technique (SCT).
Intestinal nematodes, including Toxocara canis, Toxascaris leonina, Uncinaria stenocephala and Trichuris vulpis, were found in 77.3% (95% CI 73.8-80.4%) of the examined foxes with a mean infection burden of 20.1 nematode per animal. Male and female foxes had similar infection burdens.
The nematodes are present in high prevalence and intensity among foxes in north-western Poland. Furthermore, this high prevalence of nematodes in foxes may likely constitute a health risk to humans and domestic animals due to increasing fox densities in urban and periurban areas.
赤狐（Vulpes vulpes）广泛分布于北半球和澳大利亚。城市化地区存在感染线虫的狐狸，增加了线虫传播给家犬进而传播给人类的风险。本研究的目的是确定波兰西北部省份西波美拉尼亚赤狐肠道线虫病的患病率和种类组成。使用沉淀计数技术（SCT）对在政府减少捕杀计划中捕杀的620只赤狐的肠道内容物进行成虫线虫检查。
在所检查的狐狸中，77.3%（95%可信区间73.8 - 80.4%）发现有肠道线虫，包括犬弓首蛔虫、狮弓蛔虫、窄头钩虫和狐毛首线虫，每只动物的平均感染负荷为20.1条线虫。雄性和雌性狐狸的感染负荷相似。
波兰西北部狐狸中线虫的患病率和感染强度很高。此外，由于城市和城郊地区狐狸密度增加，狐狸中线虫的这种高患病率可能对人类和家畜构成健康风险。
