| Outline of Final Research Achievements |
More than half of cases of encephalitis remain unknown. We examined the causative virus in cerebrospinal fluid samples from encephalitis children with unknown aetiology by RT-PCR. The nucleotide sequence of viral gene was identified by direct-sequencing of PCR products and phylogenetic analysis was conducted. Human adenovirus, Human herpesvirus, Human enterovirus, Human parechovirus, Human bocavirus and Human echovirus were detected in cerebrospinal fluid samples from encephalitis children. It indicated these viruses might be considered as the causative pathogen of encephalitis in children in Oita, Japan. Moreover, we evaluated high-sensitivity detection method for viral encephalitis using next generation sequencing.
