Babesia caballi and Theileria equi are the causative agents of equine piroplasmosis. In this epidemiological study, 294 horses reared in a rural area of northern Italy were studied. During January 2008-January 2009, blood samples were taken for serology (indirect fluorescent antibody test) and for polymerase chain reaction (PCR). Data on the geographical area, sex, and age were collected for statistical analysis of risk factors associated with infection. A seroprevalence of 8.5% was found: 8.2% of the animals were positive for anti-T. equi antibodies and 0.3% for anti-B. caballi antibodies. No dual infections were observed. Of those horses with positive serology to T. equi, 33% were also positive in PCR, whereas none of the seropositive horses for B. caballi was positive in PCR. No significant correlation between sex or age was found for infection status.
巴贝西原虫和马媾疫锥虫是马梨形虫病的病原体。在这项流行病学研究中，对意大利北部农村地区的 294 匹马进行了研究。2008 年 1 月至 2009 年 1 月期间，采集血样进行血清学（间接荧光抗体试验）和聚合酶链反应（PCR）检测。收集了有关地理区域、性别和年龄的数据，以对与感染相关的危险因素进行统计分析。结果发现血清阳性率为 8.5%：8.2%的动物抗马媾疫锥虫抗体阳性，0.3%的动物抗巴贝斯虫抗体阳性。未观察到双重感染。在 T. equi 血清学阳性的马中，33%的马在 PCR 中也呈阳性，而 B. caballi 血清学阳性的马在 PCR 中均为阴性。感染状态与性别或年龄之间未发现显著相关性。
