| transmission of ockelbo virus by aedes cinereus, ae. communis, and ae. excrucians (diptera: culicidae) collected in an enzootic area in central sweden. | studies were conducted to determine the ability of aedes excrucians (walker), ae. cinereus meigen, and ae. communis (de geer) group mosquitoes, collected in an ockelbo (ock) virus enzootic area in central sweden, to transmit this virus. all three species were highly susceptible to infection; at least 96% of the specimens of each species became infected after ingesting blood from a viremic chicken. recovery of virus from the legs of all 61 of the ae. excrucians and from 51% (24 of 47) and 75% (6 ... | 1990 | 2159073 |
| ecologic studies of mosquitoes and birds as hosts of ockelbo virus in sweden and isolation of inkoo and batai viruses from mosquitoes. | field studies were conducted in central sweden from 1983 through 1985 to obtain information on the etiologic agent of ockelbo disease, described in sweden in the 1960s and probably identical to pogosta disease in finland and to karelian fever in the western ussr. mosquitoes (63,644) collected during this 3 year period yielded 21 virus strains. ockelbo virus isolations were from culiseta morsitans (5 strains), culex pipiens and/or cx. torrentium (6 strains), and aedes cinereus (3 strains). inkoo ... | 1989 | 2572178 |
