| a comparison of la crosse virus isolated obtained from different ecological niches and an analysis of the structural components of california encephalitis serogroup viruses and other bunyaviruses. | analyses of the oligonucleotide fingerprints of the three genome ribonucleic acid (rna) species of 11 isolates of la crosse (lac) virus, obtained from various ecological niches in the northern united states and compared to those of prototype lac virus, showed that in each place from which these isolates were obtained lac variants and varieties were present with related, but distinguishable, nucleotide sequences for their large, medium, or small rna species. the rna genomes of prototypes trivitta ... | 1979 | 453439 |
| 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 |

| 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 |
| genotypic varieties of la crosse virus isolated from different geographic regions of the continental united states and evidence for a naturally occurring intertypic recombinant la crosse virus. | the tripartite ribonucleic acid (rna) genomes of 23 alternate isolates of la crosse virus have been analyzed by the procedure of oligonucleotide fingerprinting. by comparison with the fingerprints of the three viral rna species (large, medium and small) of prototype la crosse virus, the viruses have been categorized in terms of the degree of their rna sequence relatedness. the a type la crosse viruses, which have been recovered from wisconsin, minnesota, indiana and ohio, have viral rna sequence ... | 1981 | 7246519 |
| detection of arboviral rna directly from mosquito homogenates by reverse-transcription-polymerase chain reaction. | many arthropod-borne viruses (arboviruses) are important human pathogens medically. the development of an effective technique to detect the viruses by using nucleic acid amplification, such as polymerase chain reaction (pcr), improves not only clinical diagnosis but also virologic surveillance of mosquito vectors in the field. in this study, the development of an improved and simplified assay is described for detection of mosquitoes infected with eastern equine encephalitis (eee) virus, cache va ... | 2001 | 11337046 |
| genetic relationships of jamestown canyon virus strains infecting mosquitoes collected in connecticut. | jamestown canyon virus (jcv) (family bunyaviridae, genus orthobunyavirus) is maintained in a mosquito-deer cycle and has been implicated in the etiology of meningitis and encephalitis with human cases reported from ontario, canada, michigan, connecticut, and new york. despite the recognition of symptomatic cases in the northeastern united states, little is known about the genetic relationships of jcv variants circulating in this region. accordingly, we compared the phylogenetic relationships of ... | 2007 | 18165540 |
