| Research Abstract |
Improved system for rapid determination of viral RNA sequences (RDV) contributed to the identification and discovery of various types of the viruses. In Vietnam, Japanese encephalitis virus, Dak Nong virus (unclassified Mesonidoviridae), Culex flavivirus, Nam Dinh virus and Banna virus were isolated from mosquitoes. In the Philippines, Negev virus was isolated from Culex vishnui, and several infectious agents were found in mosquito pools. Shamonda virus and Sathuperi virus were isolated from Culicoides biting midges in Japan. PCR-based virus diagnosis was established based on the genetic information of these virus isolates. It was suggested that Aedes aegypti is regarded as the primary vector of Dengue fever in Luzon island, Philippines. The sensitivity to pyrethroid insecticide was low in Ae. aegypti. It was clarified that the pyrethroid resistance gene is widely spread throughout Luzon island.
