宫本疏螺旋体是一种日益被认识的人类病原体，在北方半球由硬蜱传播。在北美，B的感染流行。miyamotoi在肩胛硬蜱（Say;阿卡里：硬蜱科）和太平洋硬蜱（Cooley&Kohls;阿卡里：硬蜱科）中的特征性低（<10%），这两种硬蜱都容易叮咬人类。我们测试了3,255个寻找宿主的I型。2004年从加州北部沿海的门多西诺县的79个地点收集了一批太平洋白蛉，以确定是否存在B。宫本井。采集地点代表了各种森林类型，从东南部的干热橡树林地到西部的沿海红杉，以及该县北方以黄松和道格拉斯冷杉为主的地区。我们找到了那个B。miyamotoi在地理上广泛分布，但感染了I。太平洋吸虫病很少发生（累积患病率为1.4%）。感染率与地理区域或林地类型无显著相关性，无论是宿主寻求性寄生虫的密度，还是狭义伯氏疏螺旋体感染与B相关。个体蜱的miyamotoi感染状态。因为B。在同一地点的伯氏病流行率以前与林地类型和若虫密度有关，我们的研究结果表明，尽管共享一个共同的载体，但这两种病原体的地方病维持的主要模式可能不同。
Borrelia miyamotoi is an increasingly recognized human pathogen transmitted by Ixodes ticks in the Northern Hemisphere. In North America, infection prevalences of B. miyamotoi are characteristically low (<10%) in Ixodes scapularis (Say; Acari: Ixodidae) and Ixodes pacificus (Cooley & Kohls; Acari: Ixodidae), both of which readily bite humans. We tested 3,255 host-seeking I. pacificus nymphs collected in 2004 from 79 sites throughout Mendocino County in north-coastal California for presence of B. miyamotoi. The collection sites represented a variety of forest types ranging from hot, dry oak woodlands in the southeast, to coastal redwoods in the west, and Ponderosa pine and Douglas fir-dominated areas in the northern part of the county. We found that B. miyamotoi was geographically widespread, but infected I. pacificus nymphs infrequently (cumulative prevalence of 1.4%). Infection prevalence was not significantly associated with geographic region or woodland type, and neither density of host-seeking nymphs, nor infection with Borrelia burgdorferi sensu stricto was associated with B. miyamotoi infection status in individual ticks. Because B. burgdorferi prevalence at the same sites was previously associated with woodland type and nymphal density, our results suggest that despite sharing a common vector, the primary modes of enzootic maintenance for the two pathogens are likely different.
