In total, 796 serum samples of sheep on commune alpine pastures in the region of Vorarlberg were investigated by a commercial ELISA kit for antibodies against Chlamydia abortus, the agent of ovine enzootic abortion. The aim of the study was to determine the seroprevalence within this region and to compare these results with the seroprevalence in the neighboring canton Graubünden as well as to obtain data on the seroconversion after alpine pasturing. Therefore, 421 samples were collected before and 375 samples after alpine pasturing, whereas corresponding serum samples were available from 359 sheep. Within the region of Vorarlberg, a mean seroprevalence of 9.2 % was calculated with a threshold of 60 %. Seroconversion for C. abortus occurred in 5.0 % of animals with corresponding serum samples. Seroprevalence values were comparable to Swiss regions with similar management systems, although the neighboring canton Graubünden is known to have a much more higher seroprevalence of 43 %. In conclusion, the traditional animal exchange between these two regions is not significantly favoring the spread of C. abortus.
总共，使用一种用于检测抗流产衣原体抗体的商业酶联免疫吸附测定（ELISA）试剂盒，对福拉尔贝格州山区公社高山牧场的796份绵羊血清样本进行了检测，流产衣原体是绵羊地方流行性流产的病原体。本研究的目的是确定该地区的血清阳性率，并将这些结果与邻近的格劳宾登州的血清阳性率进行比较，以及获取高山放牧后血清转化的数据。因此，在高山放牧前采集了421份样本，放牧后采集了375份样本，而从359只绵羊中获得了相应的血清样本。在福拉尔贝格州地区，以60%为阈值计算出平均血清阳性率为9.2%。有相应血清样本的动物中，流产衣原体的血清转化率为5.0%。血清阳性率值与管理系统相似的瑞士地区相当，尽管已知邻近的格劳宾登州血清阳性率要高得多，为43%。总之，这两个地区之间传统的动物交换并没有显著促进流产衣原体的传播。
