Limited data currently exist on the prevalence of Toxoplasma infections in goats in the USA. The objective of this pilot investigation was to determine the prevalence of Toxoplasma gondii antibodies in Boer goats raised in Missouri. Sera collected from 367 Boer goats in 24 herds were tested using a commercial latex agglutination assay. Evidence of T. gondii antibodies was present in 25 of the 367 goats, with titres of 1 : 32 in 4, 1 : 64 in 11, 1 : 128 in 5, 1 : 256 in 3 and 1 : 1024 in 2. Estimates for the apparent animal-level and between-herd prevalence were 6.8% (95% CI = 4.7-9.9%) and 41.7% (95% CI = 24.5-61.2%). These results confirm that Boer goats in Missouri are exposed to T. gondii and may constitute a public health risks.
目前关于美国山羊弓形虫感染率的数据有限。本次初步调查的目的是确定密苏里州饲养的波尔山羊中弓形虫抗体的感染率。使用商业乳胶凝集试验对从24个畜群的367只波尔山羊采集的血清进行检测。367只山羊中有25只存在弓形虫抗体证据，其中4只滴度为1:32，11只滴度为1:64，5只滴度为1:128，3只滴度为1:256，2只滴度为1:1024。动物个体水平和畜群间的表观感染率估计分别为6.8%（95%置信区间=4.7-9.9%）和41.7%（95%置信区间=24.5-61.2%）。这些结果证实密苏里州的波尔山羊接触过弓形虫，可能构成公共卫生风险。
