| vector-host interactions and epizootiology of eastern equine encephalitis virus in massachusetts. | eastern equine encephalitis (eee) virus is a highly pathogenic mosquito-borne zoonosis that is responsible for outbreaks of severe disease in humans and equines, resulting in high mortality or severe neurological impairment in most survivors. in the northeastern united states, eee virus is maintained in an enzootic cycle involving the ornithophilic mosquito, culiseta melanura (coquillett) and passerine birds in freshwater swamp habitats. to evaluate the role of cs. melanura and culiseta morsitan ... | 2013 | 23473221 |
| dynamics of vector-host interactions in avian communities in four eastern equine encephalitis virus foci in the northeastern u.s. | eastern equine encephalitis (eee) virus (togaviridae, alphavirus) is a highly pathogenic mosquito-borne zoonosis that is responsible for occasional outbreaks of severe disease in humans and equines, resulting in high mortality and neurological impairment in most survivors. in the past, human disease outbreaks in the northeastern u.s. have occurred intermittently with no apparent pattern; however, during the last decade we have witnessed recurring annual emergence where eee virus activity had bee ... | 2016 | 26751704 |
| risk of exposure to eastern equine encephalomyelitis virus increases with the density of northern cardinals. | for a variety of infectious diseases, the richness of the community of potential host species has emerged as an important factor in pathogen transmission, whereby a higher richness of host species is associated with a lowered disease risk. the proposed mechanism driving this pattern is an increased likelihood in species-rich communities that infectious individuals will encounter dead-end hosts. mosquito-borne pathogen systems potentially are exceptions to such "dilution effects" because mosquito ... | 2013 | 23469095 |
| vector-host interactions of culiseta melanura in a focus of eastern equine encephalitis virus activity in southeastern virginia. | eastern equine encephalitis virus (eeev) causes a highly pathogenic mosquito-borne zoonosis that is responsible for sporadic outbreaks of severe illness in humans and equines in the eastern usa. culiseta (cs.) melanura is the primary vector of eeev in most geographic regions but its feeding patterns on specific avian and mammalian hosts are largely unknown in the mid-atlantic region. the objectives of our study were to: 1) identify avian hosts of cs. melanura and evaluate their potential role in ... | 2015 | 26327226 |
| a multi-year study of mosquito feeding patterns on avian hosts in a southeastern focus of eastern equine encephalitis virus. | abstract. eastern equine encephalitis virus (eeev) is a mosquito-borne pathogen that cycles in birds but also causes severe disease in humans and horses. we examined patterns of avian host use by vectors of eeev in alabama from 2001 to 2009 using blood-meal analysis of field-collected mosquitoes and avian abundance surveys. the northern cardinal (cardinalis cardinalis) was the only preferred host (fed on significantly more than expected based on abundance) of culiseta melanura, the enzootic vect ... | 2011 | 21540380 |
| west nile virus epizootiology in the southeastern united states, 2001. | we investigated mosquito and bird involvement in west nile virus (wnv) transmission in july 2001 in jefferson county, fl, and lowndes county, ga. we detected 16 wnv-infected pools from culex quinquefasciatus, cx. salinarius, cx. nigripalpus, and culiseta melanura. in florida, 11% of 353 bird sera neutralized wnv. antibody prevalence was greatest in northern cardinal (cardinalis cardinalis, 75%), northern mockingbird (mimus polyglottus, 50%), common ground-dove (columbina passerina, 25%), common ... | 2005 | 15815153 |
