| absence of la crosse virus in the presence of aedes triseriatus on the delmarva peninsula. | between 1980 and 1984, field studies were conducted in 2 areas on the delmarva peninsula to identify the presence of la crosse (lac) virus. ovitraps were used to collect eggs of aedes triseriatus complex mosquitoes. no virus was obtained from 969 pools containing 22,370 adult mosquitoes reared from eggs. only 1 of 143 raccoon serum samples had neutralizing antibody to lac virus; 36 sentinel domestic goats, and 99 other wild mammal serum samples were negative. the apparent absence of lac virus ma ... | 1986 | 3507467 |
| natural la crosse virus infection in the red fox (vulpes fulva), gray fox (urocyon cinereoargenteus), raccoon (procyon lotor), and opossum (didelphis virginiana). | natural infection of sentinel red foxes (vulpes fulva) and free-ranging red foxes, gray foxes (urocyon cinereoargenteus) and raccoons (procyon lotor) with la crosse (lac) virus was demonstrated. one isolate of lac virus was obtained from a sentinel red fox in an enzootic area. the viremia titer of the lac virus-infected red fox was above the threshold of infection for aedes triseriatus mosquitoes. antibody responses were measured by the microneutralization test employing four california group vi ... | 1981 | 7258486 |
| experimental la crosse virus infection of red fox (vulpes fulva), raccoon (procyon lotor), opossum (didelphis virginiana), and woodchuck (marmota monax). | susceptibility to infection, resulting viremia and antibody responses, and potential to provide infectious blood meals for aedes triseriatus were determined and compared for the red fox (vulpes fulva), raccoon (procyon lotor), and opossum (didelphis virginiana) exposed to la crosse (lac) virus transmitted by mosquitoes, ae. triseriatus. woodchucks (marmota monax) were infected with lac virus by needle and syringe. all 5 red foxes became viremic following the bite of a single lac virus-infected f ... | 1985 | 4003669 |
