is an obligate intracellular protozoan that causes toxoplasmosis in warm-blooded animals. Although most infections in humans and animals are subclinical, an infection can nevertheless be fatal. One of the important characteristics in the epidemiology of this parasite is waterborne transmission. The American mink (), a mammal closely adapted to freshwater ecosystems, is a potential sentinel for . We analysed meat juice from the heart of 194 wild minks collected between 2019 and 2022 in five study areas from Germany and Poland and tested for the presence of antibodies against . The analysis was performed using a commercial enzyme-linked immunosorbent assay test (ELISA). Antibodies were detected in 45.36% (88/194, 95% confidence interval (CI): 38.39-52.41%) of the analysed animals. While the prevalence values ranged from 37.50% to 49.30%, there was no significant difference in seroprevalence between the study areas. Juveniles were less likely to carry antibodies than adults (odds ratio: 0.216), whereas there was no significant difference in prevalence between the sexes (odds ratio: 0.933). The results of our study show that contact with is widespread in minks, and the parasite is common in inland freshwater ecosystems in Germany and Poland. This indicates that watercourses play an important role in the spread of oocysts.
是一种专性细胞内原生动物，可在温血动物中引起弓形虫病。虽然人类和动物的大多数感染都是亚临床的，但感染仍可能是致命的。这种寄生虫流行病学的一个重要特征是水传播。美洲水貂（）是一种与淡水生态系统密切适应的哺乳动物，是 的潜在哨兵。我们分析了2019年至2022年期间在德国和波兰的五个研究区域收集的194只野生水貂心脏的肉汁，并检测了抗 的抗体的存在。分析使用商业酶联免疫吸附试验（ELISA）进行。在45.36%（88/194，95%置信区间（CI）：38.39-52.41%）的分析动物中检测到抗体。虽然流行率值在37.50%至49.30%之间，但研究区域之间的血清流行率没有显著差异。幼年水貂比成年水貂携带 抗体的可能性更小（优势比：0.216），而两性之间的流行率没有显著差异（优势比：0.933）。我们的研究结果表明，水貂与 的接触很普遍，这种寄生虫在德国和波兰的内陆淡水生态系统中很常见。这表明水道在 卵囊的传播中起着重要作用。
