| leukocyte response to eastern equine encephalomyelitis virus in a wild passerine bird. | leukocyte counts are frequently used to assess the immunologic status of animals; however, few studies have directly looked at the predictive value of leukocyte counts and an animal's ability to respond to an infection with a pathogen. understanding how an animal's leukocyte profile is altered by an active infection can assist with interpretation of leukocyte profiles in animals for which infection status is not known. in this study we examine the leukocyte counts of gray catbirds (dumetella car ... | 2013 | 24597116 |
| 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 |
| 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 |
| experimental infection of wading birds with eastern equine encephalitis virus. | to study the susceptibility of wading birds to eastern equine encephalitis (eee) virus and to determine their potential as reservoir or amplifying hosts, fledgling glossy ibises (plegadis falcinellus) and snowy egrets (egretta thula) were captured in new jersey (usa) and shipped to colorado (usa) where they were experimentally inoculated with eee virus. all 16 snowy egrets and 14 (93%) of 15 of the glossy ibises inoculated became viremic with moderate titers, and all survivors developed neutrali ... | 1995 | 8592381 |
| antibody response of wild birds to natural infection with alphaviruses. | from 1986 to 1990, we conducted our second longitudinal study in the central (upstate) new york (cny) area on the wild avian hosts of eastern equine encephalomyelitis (eee) virus. field-collecting methods mirrored a study conducted from 1978 to 1980 at the same endemic focus. over the 5-yr study period, we captured 6,296 birds representing 99 species and took 4,174 blood samples from representatives of 83 species. gray catbirds, song sparrows, and veerys were the three dominant species captured ... | 2004 | 15605649 |
