Babesiosis is an emerging tick-transmitted zoonosis in large parts of the world. In Sweden, the occurrence and diversity of Babesia species is largely unknown. In order to estimate the exposure to Babesia from infected ticks, we collected questing Ixodes ricinus from several sites across southern Sweden during two consecutive field seasons and investigated the occurrence of Babesia species. We report for the first time the occurrence of the zoonotic species Babesia venatorum in Swedish ticks, with a prevalence of 1%. We also detected B. microti (prevalence 3.2%) and B. divergens (prevalence 0.2%). The incidence of Babesia in questing ticks is substantially lower than that of several other tick-borne diseases in Sweden. Nevertheless, babesiosis should not be neglected as a possible diagnosis following tick bites in humans and animals in Sweden.
巴贝斯虫病是世界大部分地区一种新出现的蜱传播人畜共患病。在瑞典,巴贝斯虫物种的发生情况和多样性很大程度上未知。为了估计受感染蜱传播的巴贝斯虫感染情况,我们在连续两个野外季节从瑞典南部的几个地点采集了饥饿的蓖麻硬蜱,并调查了巴贝斯虫物种的发生情况。我们首次报告了瑞典蜱中出现人畜共患病种巴贝斯虫(Babesia venatorum),患病率为1%。我们还检测到微小巴贝斯虫(患病率3.2%)和分歧巴贝斯虫(患病率0.2%)。饥饿蜱中巴贝斯虫的发病率明显低于瑞典其他几种蜱传播疾病。然而,在瑞典,蜱叮咬人和动物后,作为一种可能的诊断,巴贝斯虫病不应被忽视。
