| [Study on the etiological and molecular characteristics of aseptic meningitis epidemic in Zhejiang Province in 2002-2004]. | In order to confirm the cause of the outbreak of aseptic meningitis in Zhejiang Province in 2002-2004, trace the pathogen and analyze the molecular characteristics, 271 cerebrospinal fluid (CSF) and faeces specimens were collected from suspected patients. The virus strains from the specimens were isolated with RD and Hep-2 cell lines. The VP1 and VP4/VP2 genes of the isolated viruses were sequenced, and their phylogenetic and homology trees were also constructed. Of the total 271 samples, 78 Ech ... | 2011 | 21998959 |
