Significant neutropenia, as well as thrombocytopenia and a mild anemia, occurs in patients infected with Colorado tick fever virus. In this study, human bone marrow CD34+ cells and KG-1a cells, a human hematopoietic progenitor cell line, were infected in vitro with Colorado tick fever virus. The time course and morphological appearance of viral replication in human progenitor cells were similar to those seen in erythroblasts and in HEL cells and suggest one possible mechanism for the clinical hematologic findings.
感染科罗拉多蜱传热病毒的患者会出现显著的中性粒细胞减少,以及血小板减少和轻度贫血。在本研究中,人骨髓CD34+细胞和人造血祖细胞系KG-1a细胞在体外被科罗拉多蜱传热病毒感染。人祖细胞中病毒复制的时间进程和形态学表现与成红细胞和HEL细胞中的相似,提示了临床血液学表现的一种可能机制。
