In other words JBE virus was isolated from mosquitoes collected in nature in Okayama mix ed with Culex tritaenior hync.hus and C. pipiens var. pallens , and seven species of mosquitoes, C. tritaeniorhynchus , C . pipiens var. porllens, Aedes japonicus , A. togoi, A. albopictus, Armigeres oblurbans and Anopheles hyrcanus sinensis which were found very commo nly in Japan in the summer season were able to transmit JBE virus experimentally i n mice and in a few monkeys. Furthermore the results obtained in the experime nt on the distribution of virus in the body of artificially infected mosquitoes with JBE virus in favor of the mosquito theory, namely, it has been made clear that the virus multiplied mainly in the salivary gh nd but not in midgut or Malpighi's canal (3) . Well the mosquito theory was understood to be established first by the theoretical assumptio n independently on the foreign worker and then by the experimental basis . The seasonal fluctuation of mosquitoes in nature throu ghout the 'year in OkaYama and the relationship between the infectivity of the mosquito with JBE virus and the outbreak of epidemic had been investigated for five years from 1938 to 1942 whenever the mosquito in nature had occasionally been collected in every summer season for the virus isolation from 1933 to 1937 (Mitamura , 4, 5, 6, 7, 8, 9, 10). In Tokyo the isolation of JBE virus was undertaken from the mosquite collected i n nature in the summermonths during the period from 1945 to 1947. Furthermore the survey on the seasonal occurrence of mosquitoes in nature throughout the year a nd the infectivity of the mosquito with JBE virus have been followed up since 1948 , (11, 12, 13, 14, 15) and the zoophilia of each species of mosquitoes was investigated a s well. In this paper the seasonal fluctuation of mosquitoes in Tokyo and the zoophilia of mosquitoes were described and the virus isolation from th e mosquito and the relationship . between the mosquito and JBE virus will be publish ed in the next report .","PeriodicalId":86969,"journal":{"name":"Japanese medical journal","volume":"94 1","pages":"311-47"},"PeriodicalIF":0.0,"publicationDate":"1950-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75617293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
