| virus isolations from mosquitoes in southern ontario, 1976 and 1977. | following the 1975 epidemic of st. louis encephalitis (sle) in ontario, programs were instituted to monitor virus activity in mosquito populations during 1976 and 1977. mosquitoes were trapped with cdc light traps and co2 cone traps, pooled by species, and tested for virus by intracerebral inoculation of suckling mice. in 1976, 51 175 mosquitoes were tested. sle virus was isolated from two mixed pools of culex pipiens--c. restuans mosquitoes. five isolations of california serogroup viruses were ... | 1980 | 6103747 |
| sensitivity to carbon dioxide in mosquitoes infected with california serogroup arboviruses. | ten species of mosquitoes became sensitive to co2 following intrathoracic (i.t.) inoculation of california encephalitis (ce) virus. these included field-collected aedes melanimon, aedes nigromaculis and culiseta incidens and laboratory-colonized strains of aedes dorsalis, aedes triseriatus, anopheles freeborni, culex peus, culex pipiens pipiens, culex pipiens quinquefasciatus and culex tarsalis. another california serogroup virus, jerry slough (= jamestown canyon) (js), also induced co2 sensitiv ... | 1982 | 6122383 |
| investigations on california serogroup orthobunyaviruses in the tyrols: first description of tahyna virus in the alps. | seroprevalence rates for immunoglobulin g (igg) antibodies to tahyna virus (tahv) and inkoo virus (inkv) were determined in sera of 1630 blood donors from north, east, and south tyrol by immunofluorescence assays (ifas) and confirmatory serum neutralization tests (snts). ten sera (0.6%) reacted positive by tahv ifa, five of which (0.3%) were confirmed by snt. eleven sera (0.7%) reacted positive in the inkv ifa; only one thereof (0.06%) was verified by subsequent snt. to identify the source of in ... | 2014 | 24689784 |
