Serum samples from 5724 rams on 534 farms in New South Wales were tested in the indirect fluorescent antibody test for toxoplasmosis. Nine per cent of rams had titres of 64 or higher and 41% of flocks had either one or more rams with a titre of 64 or higher. There were significant differences in the geographical distribution of infected flocks, ranging from 57.8% of flocks infected on the tablelands to 41% on the slopes and 22.4% on the plains. There were significantly more infected commercial flocks (47.5%) than stud flocks (32.9%). The results indicated that the prevalence of infection was influenced by management, with a higher prevalence of infection in flocks kept under an intensive or semi-intensive system of management.
对新南威尔士州534个农场的5724只公羊的血清样本进行了弓形虫病间接荧光抗体检测。9%的公羊滴度为64或更高，41%的羊群中有一只或多只公羊滴度为64或更高。受感染羊群的地理分布存在显著差异，高原地区受感染的羊群占57.8%，山区为41%，平原地区为22.4%。受感染的商业羊群（47.5%）明显多于种羊场羊群（32.9%）。结果表明，感染率受管理方式影响，在集约化或半集约化管理系统下饲养的羊群中感染率较高。
