In Europe, is the most prevalent species, and this protozoan is transmitted by phlebotomine sandflies. A recent publication has shown that sheep harbor antibodies. This raises questions about the epidemiological role of small ruminants. Therefore, sera from small ruminants located in two southern German federal states, Baden-Wuerttemberg (BW) and Bavaria (BAV), were analyzed with an ELISA to determine the presence of antibodies. The species, sex and age (gimmer vs. ewe) were recorded, and a univariate analysis was conducted to determine possible associations. In total, seven sheep flocks (274 sheep/10 goats) from BW and seven sheep flocks (277 sheep/78 goats) from BAV were examined. In BW, four sheep from three flocks tested positive for antibodies. In BAV, the same number of positive sheep were detected but in four flocks. The total seropositivity rate in sheep was 1.45%. All goats tested negative. No significant association ( > 0.05) was detected between seropositivity and the variables evaluated. Our study reveals the exposure of sheep to in a non-endemic area. Further investigation is needed to determine whether sheep can be used as sentinels to identify new phlebotomine habitats and risk areas.
在欧洲，[具体物种名称]是最普遍的[具体物种名称]物种，这种原生动物通过白蛉传播。最近的一篇出版物表明绵羊体内存在[具体物种名称]抗体。这引发了关于小型反刍动物流行病学作用的问题。因此，对位于德国南部两个联邦州巴登 - 符腾堡州（BW）和巴伐利亚州（BAV）的小型反刍动物的血清进行了酶联免疫吸附测定（ELISA）分析，以确定[具体物种名称]抗体的存在情况。记录了物种、性别和年龄（青年母羊与成年母羊），并进行了单变量分析以确定可能的关联。总共检查了来自BW的7个羊群（274只绵羊/10只山羊）和来自BAV的7个羊群（277只绵羊/78只山羊）。在BW，来自3个羊群的4只绵羊[具体物种名称]抗体检测呈阳性。在BAV，检测到相同数量的阳性绵羊，但分布在4个羊群中。绵羊的总血清阳性率为1.45%。所有山羊检测均为阴性。在[具体物种名称]血清阳性与所评估的变量之间未检测到显著关联（P>0.05）。我们的研究揭示了非流行地区绵羊接触[具体物种名称]的情况。需要进一步调查以确定绵羊是否可作为哨兵来识别新的白蛉栖息地和[具体物种名称]风险区域。
