| adult body size and survivorship in a field population of aedes triseriatus. | aedes triseriatus pupae, host-seeking, and ovipositing females were collected at a southern wisconsin site endemic for la crosse encephalitis virus. the host-seeking and ovipositing females were age-graded by the detinova and polovodova techniques, respectively. wing lengths were determined for all mosquitoes. wing lengths of the mosquitoes collected as pupae were predicted from pupal weight by a simple regression equation. there was significant seasonal variation in body size of adult females, ... | 1988 | 3193107 |
| 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 |
| serologic evidence of arboviral infections in white-tailed deer from central wisconsin. | a survey conducted during 1979-1980 on white-tailed deer (odocoileus virginianus) in central wisconsin revealed serological evidence of infection by selected arboviruses. among sera from 41 deer, antibody was detected for jamestown canyon virus (56%) and bunyamwera group virus (80%), demonstrating their continuing endemic activity. antibody for la crosse virus, not found previously in sera from deer in central wisconsin, also was detected (5%) in this study. | 1989 | 2716117 |
| spatial distribution of aedes triseriatus eggs in a site endemic for la crosse encephalitis virus. | egg laying behavior in aedes triseriatus was studied in an oak woodlot endemic for la crosse encephalitis virus in southwestern wisconsin. daily counts from oviposition traps allowed the calculation of spatial distribution parameters for eggs during 1988. egg distribution along an ellipsoidal transect of 25 traps was clumped with some traps being more attractive to ovipositing female ae. triseriatus than others. females were estimated to deposit a mean of 31 +/- 9.8 eggs per oviposition. | 1990 | 2370533 |
| california serogroup virus infections in wisconsin domestic animals. | a serologic survey and experimental virus transmission studies were done to assess the role of domestic animals as amplifier hosts of la crosse (lacv) and jamestown canyon (jcv) viruses. serum from 319 cows, 88 dogs, 122 equines, 47 swine, 10 goats, and 4 cats were tested for neutralizing antibody to lacv, jcv, trivittatus (tvtv), and snowshoe hare (sshv) viruses. antibody prevalences of lacv, tvtv, and sshv were less than 10% in all species. antibody to jcv was detected in all species except ca ... | 1988 | 3189702 |

| tickborne powassan virus infections among wisconsin residents. | powassan virus (powv) is a tickborne flavivirus that causes a rare but potentially life-threatening illness. the first reported case of powv infection in a wisconsin resident occurred in 2003. enhanced surveillance and testing detected 2 additional cases. | 2010 | 20443328 |
| bloodmeal sources of aedes triseriatus and aedes vexans in a southern wisconsin forest endemic for la crosse encephalitis virus. | the micro enzyme-linked immunosorbent assay (elisa) was used to specifically identify bloodmeal sources of aedes triseriatus say and aedes vexans meigen collected at a site endemic for la crosse (lac) encephalitis virus. deer were the source of 65% of ae. triseriatus and 94% of aedes vexans bloodmeals, respectively. chipmunks and tree squirrels, which are considered to be the major vertebrate amplifying hosts of lac virus, were the sources of 8% and 16%, respectively, of the bloodmeals of ae. tr ... | 1982 | 7072901 |

| natural la crosse virus infection in the red fox (vulpes fulva), gray fox (urocyon cinereoargenteus), raccoon (procyon lotor), and opossum (didelphis virginiana). | natural infection of sentinel red foxes (vulpes fulva) and free-ranging red foxes, gray foxes (urocyon cinereoargenteus) and raccoons (procyon lotor) with la crosse (lac) virus was demonstrated. one isolate of lac virus was obtained from a sentinel red fox in an enzootic area. the viremia titer of the lac virus-infected red fox was above the threshold of infection for aedes triseriatus mosquitoes. antibody responses were measured by the microneutralization test employing four california group vi ... | 1981 | 7258486 |

| 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 |
| 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 |
