A nested polymerase chain reaction specific for Ehrlichia chaffeensis was used to attempt to amplify DNA from extracts of 100 individual ticks collected from 13 counties in central Missouri. Seventeen of 59 Amblyomma americanum and six of 41 Dermacentor variabilis ticks exhibited the characteristic 389-basepair product. This supports the hypothesis that these tick species may be vectors of human monocytic ehrlichiosis.
采用针对恰菲埃立克体的巢式聚合酶链反应，试图从密苏里州中部13个县采集的100只蜱虫个体的提取物中扩增DNA。59只美洲钝眼蜱中的17只和41只变异革蜱中的6只呈现出特征性的389碱基对产物。这支持了这些蜱虫种类可能是人类单核细胞埃立克体病传播媒介的假说。
