Serum samples from 1,000 dairy goats from northwest United States (1982 to 1984) were examined for Toxoplasma gondii antibodies by a modified agglutination test. Toxoplasma gondii antibody titers were less than 1.40 for 779 goats, 1.40 for 153 goats, and greater than or equal to 1:400 for 68 goats. Seroprevalence increased with age of goats; 3.7% of 54 six-month-old goats were seropositive (greater than or equal to 1:40) vs 17.8% of 218 one-year-old goats.
采用改良凝集试验对1982年至1984年来自美国西北部的1000只奶山羊的血清样本进行了弓形虫抗体检测。779只山羊的弓形虫抗体滴度低于1:40，153只山羊的抗体滴度为1:40，68只山羊的抗体滴度大于或等于1:400。血清阳性率随山羊年龄增长而升高；54只6月龄山羊中3.7%血清呈阳性（大于或等于1:40），而218只1岁山羊中这一比例为17.8%。
