Toward the incrimination of epidemic vectors of eastern equine encephalomyelitis virus in Massachusetts: abundance of mosquito populations at epidemic foci.
نویسندگان
چکیده
Putative epidemic/epizootic eastern equine encephalomyelitis virus (EEE) vector populations were compared at 15 recent (1982-90) human and horse case sites in Bristol and Plymouth counties in southeastern Massachusetts. Carbon dioxide-baited American Biophysics Corporation light traps were used for trapping adult mosquitoes to estimate biting risk in these foci of known transmission. Population data suggest that Coquillettidia perturbans, Aedes canadensis, and Culex salinarius are more likely vectors of EEE in Massachusetts than Aedes vexans, Anopheles punctipennis, and Anopheles quadrimaculatus.

Sampling with light traps and human bait in epidemic foci for eastern equine encephalomyelitis virus in southeastern Massachusetts.
To estimate human exposure to potential vectors of eastern equine encephalomyelitis (EEE) virus, we compared collections of putative EEE virus vectors from human biting collections with collections from CDC, AB (American Biophysics), and New Jersey light traps and resting boxes in enzootic/epidemic foci of EEE virus in southeastern Massachusetts. Human biting collections caught significantly mo...
متن کاملSusceptibility to Eastern Equine Encepkalomyelitis
In the summer of 1938 an outbreak of encephalomyelitis in man in the vicinity of Massachusetts was proved to be due to the virus of equine encephalomyetitis, Eastern strain (1). An epidemic of encephalomyelitis in horses had appeared a month before and continued during the human outbreak (2). I t was thought, although not proved, that the virus was transmitted by mosquito vectors (3). The age d...
متن کاملImpact of naled (Dibrom 14) on the mosquito vectors of eastern equine encephalitis virus.
In central New York, aerial mosquito adulticide applications have been used in response to eastern equine encephalitis (EEE) outbreaks and have targeted the swamp habitats of the primary enzootic vector of EEE virus, Culiseta melanura (Coquillett). The organophosphate insecticide naled (1, 2, dibromo-2, 2-dichloroethyl dimethyl phosphate) has been the insecticide of choice in this region. This ...
متن کاملInfection 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...

In the summer of 1938 human cases of acute encephalitis appeared in New England in sufficient numbers to warrant designating the outbreak as an epidemic.' In Massachusetts this epidemic involved more than 30 persons, mostly children, with a mortality rate of almost 75%. In the same area and at the same time, 90%o of some 250 local horses which had encephalitis died. The causative virus of easte...
