| observations on a natural cycle of la crosse virus (california group) in southwestern wisconsin. | ecological studies were conducted to document the role of the eastern chipmunk (tramias striatus) as a vertebrate host for la crosse (lac) virus in nature during late summer when aedes triseriatus mosquitoes are most abundant. movement, home range and density of chipmunk populations were determined by trap mark and recapture techniques on grid study areas. the temporal distribution of a. triseriatus was estimated by use of oviposition traps. passive antibodies were found in spring-born juveniles ... | 1974 | 4451237 |
| isolation of jamestown canyon and snowshoe hare viruses (california serogroup) from aedes mosquitoes in western massachusetts. | three isolates of jamestown canyon virus and one isolate of snowshoe hare virus (california serogroup) were obtained from adult aedes females collected in western massachusetts in 1982. jamestown canyon virus was isolated from aedes abserratus/punctor once, and from aedes intrudens twice. snowshoe hare virus was isolated from aedes stimulans group mosquitoes. la crosse encephalitis (lac) virus was not isolated from 1,552 adult aedes triseriatus, nor from 22,557 aedes triseriatus larvae. however, ... | 1993 | 8350066 |
| 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 |
