A seroepidemiological survey, using an indirect immunofluorescence test, was carried out on serum samples obtained from New Brunswick and Manitoba blood donors during 1986. The antigens were Coxiella burnetii phase I and phase II from strain Nine Mile. Eighty of the 503 (15.9%) Manitoba blood donors had a phase II antibody titer of greater than or equal to 1:8, while 41 (4.2%) of the 966 New Brunswick blood donors had such antibodies. We have recently diagnosed three cases of Q fever in New Brunswick but none have been diagnosed in Manitoba. Our data suggest that Q fever may be increasing in New Brunswick and repeated seroepidemiological studies are indicated. It is likely that undetected cases of Q fever are occurring in Manitoba.
1986年，采用间接免疫荧光试验对从新不伦瑞克省和曼尼托巴省献血者采集的血清样本进行了血清流行病学调查。抗原为来自九里株的伯纳特立克次体Ⅰ相和Ⅱ相。在503名曼尼托巴省献血者中，有80人（15.9%）Ⅱ相抗体滴度大于或等于1:8，而在966名新不伦瑞克省献血者中，有41人（4.2%）有此类抗体。我们最近在新不伦瑞克省诊断出3例Q热病例，但在曼尼托巴省未诊断出任何病例。我们的数据表明，Q热在新不伦瑞克省可能正在增加，因此需要进行重复的血清流行病学研究。很可能在曼尼托巴省存在未被发现的Q热病例。
