| seroprevalence of eastern equine encephalomyelitis virus in birds and larval survey of culiseta melanura coquillett during an interepizootic period in central ohio. | from june through august in 1999 and 2000, we conducted an avian serosurvey for eastern equine encephalomyelitis (eee) virus at killbuck marsh wildlife area (kmwa), a focus of infection in central ohio. we also monitored abundance of the suspected enzootic vector, culiseta melanura coquillett, in brown's lake bog, an adjacent wetland. of the 363 birds of 30 species sampled in 1999, three gray catbirds (dumetella carolinensis) were positive for antibodies to eee virus, representing 1.2% of the av ... | 2004 | 15266743 |
| population size, parity structure, and wing length of coquillettidia perturbans in an ohio focus of eastern equine encephalitis. | adult female density, parity status, and wing length were determined weekly for a population of coquillettidia perturbans in an area enzootic for eastern equine encephalitis virus in central ohio. samples were collected in co2-baited cdc miniature light traps from the first week in june through the 2nd week of september 1992. population density indicated a single emergence peak during the 2nd week in july. however, parity rates showed 2 peaks, occurring in the first week of august (70.9% parous) ... | 1996 | 8723260 |
| test of recrudescence hypothesis for overwintering of eastern equine encephalomyelitis virus in gray catbirds. | eastern equine encephalitis virus (eeev; family togaviridae, genus alphavirus) epizootics are infrequent, but they can lead to high mortality in infected horses and humans. despite the importance of eeev to human and animal health, little is known about how the virus overwinters and reinitiates transmission each spring, particularly in temperate regions where infected adult mosquitoes are unlikely to survive through the winter. one hypothesis to explain the mechanism by which this virus persists ... | 2011 | 21845951 |
| eastern equine encephalitis virus in ohio during 1991. | during august and september of 1991, an epizootic of eastern equine encephalitis (eee) virus in horses occurred in wayne and holmes countries, oh. this was the first recorded epizootic of eee virus in the state. twelve horses were confirmed positive for eee virus through virus isolation or seroconversion, and seven additional horses with compatible symptoms were in close spatial and temporal proximity to the confirmed cases and were presumed to have died from eee virus. the outbreak was centered ... | 1993 | 8094461 |
