Although few studies have investigated the prevalence of chlamydial infections in cattle, reported prevalence rates vary hugely. In order to assess the prevalence of this infection in cattle in Ireland, serum samples (100 herds, 20 samples/herd) collected for statutory screening for brucellosis were examined by soluble chlamydial antigen indirect ELISA. The assay detects antibodies to the two most common Chlamydiaceae spp. affecting cattle, namely Chlamydia abortus and Chlamydia pecorum. A total of 95 samples from 57 herds were seropositive, representing an observed prevalence rate of 4.75%. The parametric bootstrap estimate of the mean disease prevalence in the population was 6.04% (95%, CI 4.70-7.50). The results suggest the prevalence of chlamydial infection is low in cattle in Ireland.
尽管很少有研究调查牛群中衣原体感染的流行率，但报告的流行率差异很大。为了评估衣原体感染在爱尔兰牛群中的流行情况，对为法定布鲁氏菌病筛查而采集的血清样本（100 个牛群，每个牛群 20 个样本）进行了可溶性衣原体抗原间接 ELISA 检测。该检测方法可检测到最常见的两种感染牛的衣原体科 spp.，即流产衣原体和绵羊衣原体。共有来自 57 个牛群的 95 个样本呈血清阳性，表明观察到的流行率为 4.75%。人群中疾病流行率的参数 bootstrap 估计值为 6.04%（95%CI 4.70-7.50）。结果表明，衣原体感染在爱尔兰牛群中的流行率较低。
