Serological investigation by the indirect haemagglutination test for Toxoplasma antibodies was carried out in a flock of dairy goats. Antibody titres ranging from 1:4 to 1:1,024 were found in 34% of 371 apparently healthy animals. High antibody titres of 1:256 suggestive of recent infection were noted in 18(4.9%) animals including 13 nannies. The occurrence of a number of non-brucella abortions associated with high serological titres and the isolation of the parasite from the brain tissues of an aborted foetus suggested Toxoplasma as a probable aetiologic factor. Sera having significantly levels of haemagglutinating antibodies (greater than or equal to 1:128) were also found positive to the card agglutination test. Epidemiological aspects and the public health potential of subclinical toxoplasmosis in dairy goats are discussed.
采用间接血凝试验对一群奶山羊进行了弓形虫抗体的血清学调查。在371只表面健康的动物中，34%的动物抗体滴度在1:4至1:1024之间。18只（4.9%）动物，包括13只母羊，抗体滴度高达1:256，提示近期感染。出现了一些与高血清滴度相关的非布鲁氏菌性流产，并且从一只流产胎儿的脑组织中分离出了该寄生虫，这表明弓形虫可能是病因。血凝抗体水平显著（大于或等于1:128）的血清对卡片凝集试验也呈阳性。本文讨论了奶山羊亚临床弓形虫病的流行病学情况及其对公共卫生的潜在影响。
