A serological survey for Coxiella burnetii was undertaken on a randomly selected population of 103 Ontario sheep flocks. Twenty-two flocks had at least one positive ewe; seven flocks had two or more reactors. The positive flocks were geographically clustered northwest of Guelph. Crutch-clipping of the ewe's wool prior to lambing, and total confinement housing at lambing in winter and spring seemed to lower the probability of seroreactivity of the flock (p less than 0.05). The study suggests that sheep are not a major reservoir for Coxiella burnetii in Ontario.
对安大略省103个羊群的随机抽样群体进行了伯氏考克斯氏体血清学调查。22个羊群至少有一只阳性母羊；7个羊群有两只或更多反应动物。阳性羊群在圭尔夫市西北部呈地理聚集。在产羔前对母羊进行剪毛，以及在冬春季节产羔时完全圈养，似乎会降低羊群血清反应阳性的概率（p<0.05）。该研究表明，在安大略省，绵羊不是伯氏考克斯氏体的主要宿主。
