The Lyme disease spirochete, Borrelia burgdorferi Johnson, Schmidt, Hyde, Steigerwalt, and Brenner was discovered in blacklegged ticks, Ixodes scapularis Say at Rondeau Provincial Park, Ontario, Canada During this 2-yr study, spirochetes were found in B. burgdorferi-positive I. scapularis larvae attached to B. burgdorferi-infected white-footed mice, Peromyscus leucopus Rafinesque. Isolates of B. burgdorferi were cultured from blacklegged tick adults, and confirmed positive with polymerase chain reaction by targeting OspA and rrf (5S)-rrl (23S) genes. These findings show an endemic area for B. burgdorferi within an established population of L. scapularis at Rondeau Provincial Park.
莱姆病螺旋体，即伯氏疏螺旋体约翰逊亚种、施密特亚种、海德亚种、施泰格瓦尔特亚种和布伦纳亚种，是在加拿大安大略省朗多省立公园的黑脚蜱（肩突硬蜱）中发现的。在这项为期两年的研究中，在附着于感染伯氏疏螺旋体的白足鼠（白足鼠属拉芬斯克种）身上的伯氏疏螺旋体阳性肩突硬蜱幼虫中发现了螺旋体。从黑脚蜱成虫中培养出伯氏疏螺旋体分离株，并通过靶向OspA和rrf（5S）-rrl（23S）基因的聚合酶链反应确认呈阳性。这些发现表明，在朗多省立公园已有的肩突硬蜱种群中存在伯氏疏螺旋体的流行区域。
