Ehrlichia spp. from human and equine sources in the northeastern Unites States were detected by PCR, isolated, and propagated in the HL-60 promyelocytic leukemia cell line. Growth of Ehrlichia from both equine and human sources was enhanced by addition of retinoic acid, which causes granulocytic differentiation of the HL-60 cells. DNA sequencing of a portion of the 16S rDNA gene supported the hypothesis that the same pathogen was responsible for both equine and human granulocytic ehrlichiosis.
通过聚合酶链反应(PCR)检测了来自美国东北部人类和马源的埃立克体属细菌,进行分离,并在HL-60早幼粒细胞白血病细胞系中传代培养。添加视黄酸可促进来自马源和人源的埃立克体生长,视黄酸可使HL-60细胞发生粒细胞分化。16S核糖体DNA(rDNA)基因部分序列的DNA测序支持了以下假说:同一病原体导致了马和人的粒细胞埃立克体病。
