| antibodies to la crosse virus in eastern chipmunks in indiana near an aedes albopictus population. | blood samples of 34 eastern chipmunks trapped in the vicinity of an aedes albopictus population near new alsace, in, were tested for neutralizing antibodies to la crosse (lac) virus and other california group viruses. two samples were positive for lac antibodies. analysis of mosquito bloodmeals demonstrated that both ae. albopictus and ae. triseriatus from the site fed on chipmunks. this note documents the first record of lac antibodies in sylvan rodents from indiana, the presence of lac virus i ... | 1991 | 1787412 |
| seroconversion rates to jamestown canyon virus among six populations of white-tailed deer (odocoileus virginianus) in indiana. | the annual seroconversion of fawns, yearlings, and adult white-tailed deer (odocoileus virginianus) to jamestown canyon virus (california group) was followed at six indiana sites from 1981 through 1984. in all, sera from 1,642 deer (515 fawns, 618 yearlings, and 509 adults) were tested for neutralizing antibody to three california serogroup viruses: jamestown canyon, la crosse, and trivittatus. virtually all deer with specific neutralizing antibody showed evidence of a prior infection with james ... | 1987 | 3820426 |
| serologic evidence for widespread infection with la crosse and st. louis encephalitis viruses in the indiana human population. | the vast under-reporting of la crosse virus and st. louis encephalitis virus infections in indiana residents was evident when numerous inapparent infections were detected retrospectively using serum dilution neutralization analyses of serum obtained in november 1978-april 1979 from 10,208 persons (0.2% of the state's population). an antibody prevalence rate of 3.6% to st. louis encephalitis virus was detected in the sample population as a whole, with rates as high as 13.2% for residents of indiv ... | 1984 | 6328975 |
| 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 |
