We evaluated the potential for several North American mosquito species to transmit the newly introduced West Nile (WN) virus. Mosquitoes collected in the New York City Metropolitan Area during the recent (1999) WN outbreak were allowed to feed on chickens infected with WN virus isolated from a crow that had died during this outbreak. These mosquitoes were(More)
Modern neuroimaging technologies allow scientists to uncover interspecies differences and similarities in hemispheric asymmetries that may shed light on the origin of brain asymmetry and its functional correlates. We analyzed asymmetries in ratios of white to grey matter in the lateral aspect of the lobes of the brains of chimpanzees. We found marked(More)
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(More)
Ochlerotatus japonicus (Theobald) collected in gravid traps were held individually in modified BioQuip breeders in a darkened room under ambient conditions and readily oviposited on Styrofoam blocks. Counts were made of eggs laid on Styrofoam blocks, container sides, and water surface, and dissections allowed for counts of retained eggs to determine the(More)
The host-feeding patterns of Anopheles quadrimaculatus Say and Anopheles punctipennis (Say) were examined in order to evaluate their potential contributions to the transmission of eastern equine encephalitis virus (EEEv) and other arboviruses in the northeastern U.S.A. Engorged mosquitoes of the two species were collected from EEEv foci in central New York(More)
A regional surveillance system for eastern equine encephalitis (EEE) virus was established in central New York in 1984 after the 2nd human EEE fatality occurred in 1983. Extensive mosquito surveillance activities were coordinated with the rapid laboratory processing of mosquito specimens for EEE virus. Active surveillance for EEE infections in humans and(More)
Eastern equine encephalitis (EEE) virus perpetuates in an enzootic cycle involving ornithophilic mosquito vectors, principally Culiseta melanura (Coquillett) and avian amplification hosts. To better understand the role of Cs. melanura and Culiseta morsitans (Theobald) in the epizootiology of EEE virus, we collected blood-fed mosquitoes between 31 May and 15(More)
Admission to hospital has been found to have a negative impact on people with dementia. The Scottish Dementia Champions programme was developed to prepare health and social service Dementia Champions working in acute settings as Change Agents. The programme was initially delivered to a cohort of 100 health professionals via blended learning, and comprised(More)
Tires and other water-holding containers throughout New York State were sampled during 2000 for the presence of immature or adult Ochlerotatus japonicus to determine the geographic distribution of this species. Waste tire stockpiles were one of the primary sites surveyed. Immature or adult Oc. japonicus were confirmed in 18 counties in New York State,(More)
A West Nile virus (WNV) surveillance system was created and implemented in New York State (NYS) in 2000 and described previously (White et al. 2001). We examine and evaluate the results of mosquito and virus surveillance for 2000 through 2004 exclusive of New York City. Forty-nine counties submitted 1,095,426 mosquitoes in 35,280 pools for WNV assay.(More)
