| Outline of Final Research Achievements |
Human metapneumovirus (HMPV) is an important cause of lower respiratory tract infections in young children. Because of its slow replication and weak cytopathic effect in cultured cells, conventional neutralization assays for HMPV require about one week for completion. In this study we established a rapid neutralization assay based on a recombinant virus expressing highly sensitive luciferase genes. This assay could be completed within 12 h and eliminated the requirement of trypsin supporting multistep replication in cultured cells, as well as laborious processes including the plaque assay with immunostaining. Thus we succeeded in establishing the novel neutralization assay for HMPV, which is the fastest and the most straightforward of all previous assays and may be available for high throughput screening of neutralizing antibodies.
