Eastern equine encephalomyelitis virus and Culiseta melanura activity at the Patuxent Wildlife Research Center, 1985-90.
Mosquito population densities, virus isolations and seroconversion in sentinel quail were used to monitor eastern equine encephalomyelitis virus (EEE) activity at the Patuxent Wildlife Research Center, Laurel, Maryland, from 1985 through 1990. A dramatic increase in the number of Culiseta melanura collected in 1989, as compared with the 3 previous years, was associated with virus isolations from this species (5/75 pools; n = 542 mosquitoes) and with seroconversion in sentinel quail (4/22 birds positive). This was the first detection of EEE virus activity in this area since a 1984 EEE outbreak killed 7 whooping cranes.
