Serum samples from yearling Thoroughbred horses (n = 176) in the magisterial districts of Colesberg, Venterstad, and Wodehouse in the Northern and Eastern Cape Provinces were collected between September and November 1995 to determine the prevalence of antibodies to Babesia equi and Babesia caballi in these regions. Samples were examined for specific antibodies using the indirect fluorescent antibody test. The 95% confidence intervals for the prevalence of serum antibodies in the 3 districts combined varied from 47% to 61% for B. equi and from 26% to 40% for B. caballi. Antibody prevalence did not correlate with the known distributions of the tick vectors (Rhipicephalus evertsi evertsi and Hyalomma truncatum). Colts had a significantly higher prevalence of antibodies against B. caballi than fillies. No such difference could be determined for B. equi.
1995年9月至11月期间，在北开普省和东开普省的科尔斯堡、文特斯塔德和沃德豪斯治安区采集了176匹一岁纯种马的血清样本，以确定这些地区马巴贝斯虫和驽巴贝斯虫抗体的流行情况。使用间接荧光抗体试验检测样本中的特异性抗体。三个地区血清抗体流行率的95%置信区间，马巴贝斯虫为47%至61%，驽巴贝斯虫为26%至40%。抗体流行率与已知的蜱传播媒介（南非小旋蜱和截形璃眼蜱）分布无关。公马抗驽巴贝斯虫抗体的流行率显著高于母马。对于马巴贝斯虫，未发现此类差异。
