在1985年和1986年的产羔季节，纽约州科布斯基尔一个农场的200只母羊中有29只（14.5%）流产或产羔死亡。15只流产母羊中13只经改良凝集试验检测弓形虫抗体滴度高（1,024），1只胎儿组织中分离出弓形虫。1987年产羔季节有5只母羊流产，但不是因为感染弓形虫。1987年1月，从592只母羊血清中检出弓形虫抗体，阳性率为73.8%，表明该场存在地方性弓形虫病。血清阳性率随年龄增加; 40.2%的1岁母羊与89.2%的2岁母羊可检测到抗体。
Twenty-nine of 200 (14.5%) ewes on a farm in Cobleskill, NY aborted or had dead lambs during the lambing seasons of 1985 and 1986. Thirteen of 15 ewes that aborted had high Toxoplasma gondii antibody titers (1,024), via the modified agglutination test, and T gondii was isolated from the tissues of 1 fetus. In the 1987 lambing season, 5 ewes aborted, but not because of T gondii infection. Toxoplasma gondii antibodies were detected in 73.8% of sera obtained from 592 ewes in January 1987, indicating enzootic toxoplasmosis on this farm. Seropositivity increased with age; 40.2% of 1-year-old ewes had detectable antibody vs 89.2% of 2-year-old ewes.
