title: Filamentous structures in dengue type 3 virus infected mouse neurones.
abstract: Dengue type 3 (H-87) virus was inoculated into suckling mouse brain and animals were sacrificed at 24 hr intervals. Parallel filamentous structures were found in infected neurones in close association with virus particles in the distended endoplasmic cisternae. They were usually arranged in a crystalloid pattern, oriented in different directions within the cisternae. Faint helical features were sometimes observed. These filamentous structures measured 15-25 nm in width and varied in length. Their possible involvement with viral material or a viral core is postulated.
