疫苗株病毒引起1例成人水痘的病原分离与鉴定

本文旨在探讨1例由疫苗株病毒引起成人水痘的病例,以提高对水痘疫苗二次传播的认识。从1名23岁女性水痘患者皮肤水疱中采集水疱液,接种至人胚胎成纤维细胞,3d后观察到细胞发生病变效应。用水痘-带状疱疹病毒gE`糖蛋白单克隆抗体间接免疫荧光法鉴定,结果阳性。测序分析显示,分离到的毒株其疫苗相关的单核苷酸多态性位点与Oka疫苗株一致,为疫苗株病毒。回顾性调查显示,患者没有水痘史和疫苗接种史,病毒可能来自1名与患者直接接触的接种疫苗后发生带状疱疹的儿童。

A case of adult varicella attributable to a vaccine virus

The present paper aims to report a case of adult varicella attributable to the vOka vaccine, and to raise our awareness of secondary transmission through vaccination. A 23 year-old woman presented to hospital with a mild varicella infection. The fluid of the skin lesions was aspirated and inoculated to human embryonic fibroblasts. The cytopathic effect (CPE) was observed 3 days later and identified by indirect immunofluorescence using monoclonal antibodies against glycoprotein E of varicella-zoster virus (V...
