In the midgut epithelium of Aedes albopictus (Oahu strain) orally infected with chikungunya virus, the distribution of the virus at day 3 and 14 postinfection was observed using electron microscopy. The virus cores in the cytoplasma, virus particles budding from a cytoplasmic extension to the basal labyrinth and a large number of mature virus particles in the basal labyrinth, were observed on day 3 post-infection. The virus particles were observed in the opening of the basal labyrinth and basal lamina. On day 14 post-infection, many virus particles in the basal labyrinth and massive particles in the basal lamina were observed. There were few virus particles in the basal lamina compared with many virus particles in the basal labyrinth. This observation suggests that the virus particles do not pass through a basal lamina readily; and also, that the massive virus particles observed in the basal lamina were one process for the virus to disseminate into the hemocoel side from the midgut epithelial cells.
