Sera from 155 ewes representing 21 different sheep flocks from the central parts of Sweden were examined for the presence of antibodies to Toxoplasma gondii by the indirect fluorescent-antibody test. Seropositive animals were found in 14 flocks, which corresponded to 55 % of the tested sera. Animals from the same flock were with few exceptions either all positive or all negative. Some ewes with a history of abortion a few months before blood sampling showed high titers indicating causative correlation with toxoplasmosis. These are the first verified cases of ovine toxoplasmal abortions in Sweden.
通过间接荧光抗体试验，对来自瑞典中部21个不同羊群的155只母羊的血清进行检测，以检查是否存在抗弓形虫抗体。在14个羊群中发现了血清阳性动物，这相当于所检测血清的55%。同一羊群中的动物除少数例外，要么全部呈阳性，要么全部呈阴性。一些在采血前几个月有流产史的母羊显示出高滴度，表明与弓形虫病存在因果关系。这些是瑞典首批经证实的绵羊弓形虫流产病例。
