在罗得岛州的34个地点测定了感染白足鼠（Peromyscus leucopus Rafinesque）的小巴贝斯虫脊体的人畜共患流行率，这些地点的黑脚蜱（Ixodes scapularis Say）的密度从低到高不等（每小时标记1.7-525.3只）。巴贝斯虫仅在蜱虫丰度中高（每小时约有20只若虫）的地点检测到，且呈块状分布。在检测到巴贝斯虫的地点，每小时采集的蜱虫平均数量为229.2只，而在未检测到巴贝斯虫的地点，每小时采集的蜱虫平均数量为40.1只。将巴贝虫的空间发生与地理信息系统中的蜱虫密度数据库相结合，有可能预测人畜共患和人类感染巴贝虫的模式。
Zoonotic prevalence of Babesia microti Franca piroplasms infecting white-footed mice, Peromyscus leucopus Rafinesque, was determined at 34 sites in Rhode Island where nymphal blacklegged tick, Ixodes scapularis Say, densities ranged from low to hyperabundant (1.7-525.3 nymphs per hour of flagging). Babesia was only detected at sites where tick abundance was moderate to high (>20 nymphs per hour of flagging) and appeared to exhibit a clumped distribution. Where B. microti was detected, the mean number of nymphal ticks collected per hour of flagging was 229.2 compared with a mean of 40.1 at sites where Babesia was not detected. By combining the spatial occurrence of Babesia with a tick density database in a geographic information system, it may be possible to predict the pattern of zoonotic and human infection with B. microti.
