| california serogroup viruses in new york state: the role of subtypes in human infections. | the roles of various subtypes of the california serogroup viruses as infectious agents and as neuropathogens were evaluated by using the plaque reduction neutralization test. sera from 394 patients with central nervous system (cns) infections during 1971-1982 and from 501 persons without cns manifestations were studied. jamestown canyon (jc) and la crosse (lac) viruses were found to have been common infectious agents in new york state for at least 16 years. jc virus was the prevalent indicated a ... | 1984 | 6507732 |
| oral transmission of jamestown canyon virus by aedes provocans mosquitoes from northeastern new york. | aedes provocans were allowed to feed on a bloodmeal containing 5.6 log10 tcid50/ml of jamestown canyon (jc) virus. after 14 days of incubation at 21 degrees c and 80% rh, 100% (36/36) were midgut infected, 50% (18/36) developed disseminated infections and 50% (9/18) of the latter specimens transmitted virus to capillary tubes. when mosquitoes were intrathoracically inoculated with 6.1 log10 tcid50/ml of jc virus, 100% (40/40) became disseminated infected and 95% (38/40) transmitted virus after 1 ... | 1991 | 1675258 |
| incrimination of aedes provocans as a vector of jamestown canyon virus in an enzootic focus of northeastern new york. | a 2-year field study was conducted in southern saratoga county, new york, to determine which species of the aedes communis group mosquitoes were potential vectors of jamestown canyon (jc) virus. a total of 23,890 mosquitoes (890 pools) were processed for virus isolation in 1988-89, yielding 17 jc virus isolates from ae. provocans and one isolate each from ae. communis, ae. intrudens and ae. punctor. minimum field infection rates (mfir) and daily mfirs as high as 1:219 and 1:38, respectively, wer ... | 1990 | 2230781 |
