Susceptibility of mosquito and lepidopteran cell lines to the mosquito iridescent virus (IIV-3) from Aedes taeniorhynchus.

Transmission of African Horse-Sickness by Means of Mosquito Bites and Replication of the Virus in Aedes aegypti

Sublethal iridovirus disease of the mosquito Aedes aegypti is due to viral replication not cytotoxicity.

Invertebrate iridescent viruses (Iridoviridae) possess a highly cytotoxic protein. In mosquitoes (Diptera: Culicidae), invertebrate iridescent virus 6 (IIV-6) usually causes covert (inapparent) infection that reduces fitness. To determine whether sublethal effects of IIV-6 are principally due to cytotoxicity of the viral inoculum (which inhibits macromolecular synthesis in the host), or caused ...

Seasonality, prevalence and pathogenicity of the gregarine Ascogregarina taiwanensis (Apicomplexa: Lecudinidae) in mosquitoes from Florida.

Aedes albopictus larvae collected in Gainesville, FL, were infected with the gregarine Ascogregarina taiwanensis. Natural prevalence varied from 68 to 100%. Eight mosquito species were tested in the laboratory for susceptibility to A. taiwanensis isolated from field-collected Ae. albopictus. Aedes aegypti, Aedes albopictus, and Aedes taeniorhynchus became 100% infected in the larval stage, wher...

Genome of invertebrate iridescent virus type 3 (mosquito iridescent virus).

Iridoviruses (IVs) are classified into five genera: Iridovirus and Chloriridovirus, whose members infect invertebrates, and Ranavirus, Lymphocystivirus, and Megalocytivirus, whose members infect vertebrates. Until now, Chloriridovirus was the only IV genus for which a representative and complete genomic sequence was not available. Here, we report the genome sequence and comparative analysis of ...

Infection and dissemination of Venezuelan equine encephalitis virus in the epidemic mosquito vector, Aedes taeniorhynchus.

The mosquito Aedes taeniorhynchus is an important epidemic vector of Venezuelan equine encephalitis virus (VEEV), but detailed studies of its infection are lacking. We compared infection by an epidemic VEEV strain to that by an enzootic strain using virus titrations, immunohistochemistry, and a virus expressing the green fluorescent protein. Ae. taeniorhynchus was more susceptible to the epidem...
