| stabilized infection of california encephalitis virus in aedes dorsalis, and its implications for viral maintenance in nature. | three populations of aedes dorsalis were selected which transmitted california encephalitis (ce) virus vertically to over 90% of their progeny. infected progeny in these subpopulations transmitted virus at similar rates through five generations; females from the last generation transmitted virus by bite to suckling mice. these high rates of vertical transmission appeared to be due to the development of a stabilized infection with ce virus rather than to genetic selection for a more efficient tra ... | 1982 | 7149111 |
| transovarial and trans-stadial transmission of california encephalitis virus in aedes dorsalis and aedes melanimon. | california encephalitis (ce) virus was transmitted transovarially by its natural vectors, aedes dorsalis and aedes melanimon following infection by intrathoracic inoculation. virus was recovered from adult ae. melanimon reared from eggs that were stored for up to 19 months and exposed to repeated freezing and thawing. neither time since oviposition nor storage conditions affected infection rates in surviving embryos. survival rates were highest in eggs stored at 4 degrees c. transovarial infecti ... | 1982 | 6889818 |
| carbon dioxide sensitivity of mosquitoes infected with california encephalitis virus. | four species of mosquitoes became sensitive to carbon dioxide approximately 3 to 4 days after they received intrathoracic injectins of california encephalitis virus. aedes melanimon and aedes dorsalis infected orally with california encephalitis virus also became carbon dioxide-sensitive, but mosquitoes infected transovarially did not. sensitivity to carbon dioxide was inhibited by antiserum to california encephalitis virus. to our knowledge this is the first report of carbon dioxide sensitivity ... | 1980 | 6773145 |
