The prevalence of toxoplasma antibodies (Sabin and Feldman’s dye test) was examined in 1929 lambs and mature sheep from 4 different parts of the southern Norway. Blood samples were collected from 1377 lambs from 211 flocks at slaughtering during September and October in 1968 and 1969, and from 552 ewes from 65 flocks during the winters of 1970—1971 and 1971—1972. Toxoplasma antibodies were found in 20—39 % of the lambs, and in 42—50 % of the mature ewes. The prevalence of flocks with at least 1 dye test positive (titre ≥ 1/16) lamb ranged between 48 and 80 %, and of flocks with at least 1 dye test positive breeding ewe between 79 and 90 %. The results from each part of the country are discussed, and conclusions of regional differences in the epidemiology of Toxoplasma gondii are deduced. In spite of variations in the epidemiological pattern, no evidence was found of significant differences in the geographical distribution of the parasite.
对来自挪威南部4个不同地区的1929只羔羊和成年绵羊进行了弓形虫抗体（萨宾和费尔德曼染色试验）患病率检测。在1968年和1969年9月及10月屠宰时，从211个羊群的1377只羔羊采集了血样，在1970 - 1971年和1971 - 1972年冬季，从65个羊群的552只母羊采集了血样。在20% - 39%的羔羊和42% - 50%的成年母羊中发现了弓形虫抗体。至少有1只染色试验呈阳性（滴度≥1/16）羔羊的羊群患病率在48%至80%之间，至少有1只染色试验呈阳性繁殖母羊的羊群患病率在79%至90%之间。对该国各地区的结果进行了讨论，并推断出弓形虫病流行病学区域差异的结论。尽管流行病学模式存在差异，但未发现该寄生虫地理分布存在显著差异的证据。
