人类小DNA病毒B19(Parvovirus B19,本文简称B19)的发展历史较短,它是1975年筛查健康献血员中乙型肝炎时偶然发现的。Cossart用免疫扩散的方法发现了编号为“B19”的一批志愿者血液没带有乙型肝炎病毒而带有另外一种病毒,于是用“B19”命名了这一病毒。“B19“是指第一次分离时标本的编号,更合理的选择应是“HPV”即Human Parvovirus。但是这一首字母 The history of the human small DNA virus B19 (Parvovirus B19, referred to as B19 for short) has a relatively short history of discovery and was occasionally revealed in 1975 in the screening of hepatitis B in healthy blood donors.
