The purpose of this study was to describe the geographic distribution and model the ecological niche for Borrelia burgdorferi (Johnson, Schmidt, Hyde, Steigerwaldt & Brenner), Ixodes pacificus (Cooley & Kohls), and Ixodes angustus (Neumann), the bacterium and primary tick vectors for Lyme disease, in British Columbia (BC), Canada. We employed a landscape epidemiology approach using geographic information systems mapping and ecological niche modeling (Genetic Algorithm for Rule-set Prediction) to identify geographical areas of disease transmission risk. Forecasted optimal ecological niche areas for B. burgdorferi are focused along the coast of Vancouver Island, the southwestern coast of the BC mainland, and in valley systems of interior BC roughly along and below the N51 degree line of latitude. These findings have been used to increase public and physician awareness of Lyme disease risk, and prioritize future field sampling for ticks in BC.
本研究旨在描述加拿大不列颠哥伦比亚省（BC）莱姆病的病原体博氏疏螺旋体（Johnson、Schmidt、Hyde、Steigerwaldt 和 Brenner）、太平洋硬蜱（Cooley 和 Kohls）和安氏革蜱（Neumann）的地理分布，并对其生态位进行建模。我们采用了景观流行病学方法，利用地理信息系统制图和生态位建模（遗传算法规则集预测）来确定疾病传播风险的地理区域。博氏疏螺旋体的预测最佳生态位区域集中在温哥华岛沿海、BC 大陆的西南沿海，以及 BC 内陆沿 N51 纬度线及其以下的山谷系统中。这些发现已被用于提高公众和医生对莱姆病风险的认识，并优先考虑在 BC 进行未来的蜱虫实地采样。
