| potential effect of global warming on mosquito-borne arboviruses. | if global warming occurs in california, daily mean temperatures may increase by 3 to 5 degrees c, precipitation patterns will change, and sea level may rise 1 m. studies were done on effect of temperature changes on survival of culex tarsalis coquillett, the primary vector of western equine encephalomyelitis (wee) and st. louis encephalitis (sle) viruses, in two regions where temperatures differed by 5 degrees c. daily mortality of adult vectors increased by 1% for each 1 degree c increase in te ... | 1994 | 8057305 |
| prevalence of antibodies to western equine encephalomyelitis and st. louis encephalitis viruses in residents of california exposed to sporadic and consistent enzootic transmission. | sera from outpatients attending county health department clinics in areas of california with consistent (imperial valley) and sporadic (sacramento valley) enzootic transmission of western equine encephalomyelitis (wee) and st. louis encephalitis (sle) viruses exhibited neutralizing antibody prevalence rates of 1.3% (n = 690) and 0.5% (n = 1,066) for wee and 11.0% and 0.8% for sle, respectively. seroprevalence for sle virus in imperial county increased as a function of both age and years of resid ... | 1997 | 9392590 |
| limited interdecadal variation in mosquito (diptera: culicidae) and avian host competence for western equine encephalomyelitis virus (togaviridae: alphavirus). | historically, western equine encephalomyelitis virus (weev) caused large equine and human epidemics in the americas from canada into argentina. despite recent enhanced surveillance for west nile virus, there have been few reports of equine or human cases and little documented enzootic activity of weev. during the past three years, weev has been active again in california, but without human or equine cases. in the current study, we compared host and vector competence of representative weev isolat ... | 2008 | 18385369 |
| persistent west nile virus transmission and the apparent displacement st. louis encephalitis virus in southeastern california, 2003-2006. | west nile virus (family flaviviridae, genus flavivirus, wnv) invaded the colorado desert biome of southern california during summer 2003 and seemed to displace previously endemic st. louis encephalitis virus (family flaviviridae, genus flavivirus, slev, an antigenically similar flavivirus in the japanese encephalitis virus serocomplex). western equine encephalomyelitis virus (family togaviridae, genus alphavirus, weev), an antigenically distinct alphavirus, was detected during 2005 and 2006, ind ... | 2008 | 18533445 |
