| california arbovirus (la crosse) infections. iii. epidemiology of california encephalitis in minnesota. | mosquitoes (eggs, larvae, and adults), small woodland animals, and residents of an area where california encephalitis is endemic were studied to elucidate the host-vector cycle of la crosse virus. elementary schoolchildren from surrounding communities and gray squirrels from another area were tested to compare the prevelence of serum antibodies to la crosse virus in areas where the disease is endemic with the prevalence of these antibodies in areas where the disease is not endemic. from 1971 to ... | 1976 | 3613 |
| 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 |
| california arbovirus (la crosse) infections. ii. precipitin antibody tests for the diagnosis of california encephalitis. | precipitin antibodies to california group arboviruses were studied by double agar gel immunodiffusion (id) and counterimmunoelectrophoresis (cep). forty children with california encephalitis (ce), 12 patients with other forms of meningoencephalitis, and 120 residents of endemic ce areas were tested. precipitin antibodies were detected only in the 40 patients with ce, whereas hemagglutination-inhibiting, neutralizing, and complement-fixing antibodies were also found in persons without a history o ... | 1973 | 4361728 |

| 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 |
| potential for la crosse virus segment reassortment in nature. | the evolutionary success of la crosse virus (lacv, family bunyaviridae) is due to its ability to adapt to changing conditions through intramolecular genetic changes and segment reassortment. vertical transmission of lacv in mosquitoes increases the potential for segment reassortment. studies were conducted to determine if segment reassortment was occurring in naturally infected aedes triseriatus from wisconsin and minnesota in 2000, 2004, 2006 and 2007. mosquito eggs were collected from various ... | 2008 | 19114023 |
