vector competence of north american mosquitoes (diptera: culicidae) for west nile virus.	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 wn virus outbreak, at the assateague island wildlife refuge, va, or from established colonies were allowed to feed on chickens infected with wn virus isolated from a crow that died during the 1999 outbreak. these mosquitoes were tested approximately 2 wk later to determine infection, disseminati ...	2001	11296813
potential north american vectors of west nile virus.	the outbreak of disease in the new york area in 1999 due to west nile (wn) virus was the first evidence of the occurrence of this virus in the americas. to determine potential vectors, more than 15 mosquito species (including culex pipiens, cx. nigripalpus, cx. quinquefasciatus, cx. salinarius, aedes albopictus, ae. vexans, ochlerotatus japonicus, oc. sollicitans, oc. taeniorhynchus, and oc. triseriatus) from the eastern united states were evaluated for their ability to serve as vectors for the ...	2001	11797788
experimental transmission of st. louis encephalitis virus by ochlerotatus j. japonicus.	ochlerotatus japonicus japonicus a newly discovered nonindigenous mosquito species in north america, and a colonized strain of culex pipiens were compared for their vector competence for st. louis encephalitis virus (sle). infection rates in oc. j. japonicus were 0-33% after feeding on chickens with viremias between 10(4.1) and 10(4.7) plaque-forming units (pfu)/ml of blood. in comparison, infection rates were 12-94% for cx. pipiens that fed on the same chickens. when fed on chickens with viremi ...	2003	12825669
host preferences in host-seeking and blood-fed mosquitoes in switzerland.	the avian zoonotic agent for west nile virus (wnv) can cause neuroinvasive disease in horses and humans and is expanding its range in europe. analyses of the risk for transmission to these hosts in non-endemic areas are necessary. host preferences of mosquitoes (diptera: culicidae), the main vectors of wnv, were determined in switzerland using animal-baited trap (horse, chickens) experiments at a natural and a periurban site. this was undertaken on four occasions during may-september 2014. in ad ...	2016	26685926
resource-effective serosurveillance for the detection of west nile virus in switzerland using abattoir samples of free-range laying hens.	west nile virus (wnv) is an important zoonotic pathogen maintained in a natural transmission cycle between mosquitoes and birds as reservoir hosts. in dead-end hosts, such as humans, infection may result in fatal neurologic disease translating into disease and death-related suffering and increased health care costs. in humans, wnv may also be transmitted through blood transfusions and organ transplants. wnv is not present in switzerland yet, but competent vector species (especially culex pipiens ...	2019	30457933
