Little has been known about the zoonotic parasite in the remote isolated archipelago of the Faroe Islands. This study was conducted to estimate seroprevalence in domestic sheep in the Faroe Islands. We tested samples from 122 sheep slaughtered for human consumption in October 2021 for presence of antibodies against the parasite using a commercial multi-species ELISA. The sheep originated from 14 land lots across the Faroe Islands. Four sheep were seropositive for , corresponding to a seroprevalence estimate of 3.3 %. All four seropositive sheep were adult ewes; the seroprevalence estimate among adult ewes was 19.0 %. At least one seropositive sheep was found from three of the 14 land lots (21.4 %). All seropositive sheep were adult ewes, suggesting acquired infections from oocysts. The infections occurred in three distant out-fields, indicating multifocal environmental oocyst contamination.
对于法罗群岛这个偏远孤立的群岛中的人畜共患寄生虫，人们了解甚少。本研究旨在估计法罗群岛家养绵羊的血清阳性率。我们使用商业多物种酶联免疫吸附测定法（ELISA），检测了2021年10月为供人类食用而屠宰的122只绵羊的样本，以检测是否存在针对该寄生虫的抗体。这些绵羊来自法罗群岛的14个地块。有4只绵羊对该寄生虫血清呈阳性，血清阳性率估计为3.3%。所有4只血清呈阳性的绵羊均为成年母羊；成年母羊中的血清阳性率估计为19.0%。在14个地块中的3个地块（21.4%）发现了至少一只血清呈阳性的绵羊。所有血清呈阳性的绵羊均为成年母羊，表明是从卵囊中获得的感染。感染发生在三个遥远的外场，表明存在多灶性环境卵囊污染。
