Phylogenetic analysis revealed that some JEV strains have recently migrated from south-east and continental east Asian countries. One phylogenetic subcluster of the JEV strains circulating in Japan was closely related to viruses isolated in Vietnam and China's inland region while other JEV subclusters were related to viruses isolated in Shanghai, China. One virus subcluster, however, was isolated solely in Japan and was not found in any other Asian country. Therefore, our data suggests that the JEVs that have remained or are circulating in Japan include a mixture of viruses that have previously migrated from south-east and continental east Asian countries.<\/jats:p>","DOI":"10.1099\/vir.0.007617-0","type":"journal-article","created":{"date-parts":[[2009,3,10]],"date-time":"2009-03-10T18:38:47Z","timestamp":1236710327000},"page":"827-832","source":"Crossref","is-referenced-by-count":48,"title":["Evidence of frequent introductions of Japanese encephalitis virus from south-east Asia and continental east Asia to Japan"],"prefix":"10.1099","volume":"90","author":[{"given":"Takeshi","family":"Nabeshima","sequence":"first","affiliation":[{"name":"Department of Virology, Institute of Tropical Medicine, Nagasaki University, Sakamoto-machi 1-12-4, Nagasaki City 852-8523, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hyunh Thi Kim","family":"Loan","sequence":"additional","affiliation":[{"name":"National Institute of Hygiene and Epidemiology, Hanoi, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shingo","family":"Inoue","sequence":"additional","affiliation":[{"name":"Department of Virology, Institute of Tropical Medicine, Nagasaki University, Sakamoto-machi 1-12-4, Nagasaki City 852-8523, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Makoto","family":"Sumiyoshi","sequence":"additional","affiliation":[{"name":"Department of Virology, Institute of Tropical Medicine, Nagasaki University, Sakamoto-machi 1-12-4, Nagasaki City 852-8523, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yasuhiro","family":"Haruta","sequence":"additional","affiliation":[{"name":"Department of Virology, Institute of Tropical Medicine, Nagasaki University, Sakamoto-machi 1-12-4, Nagasaki City 852-8523, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Phan Thi","family":"Nga","sequence":"additional","affiliation":[{"name":"National Institute of Hygiene and Epidemiology, Hanoi, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vu Thi Que","family":"Huoung","sequence":"additional","affiliation":[{"name":"National Institute of Hygiene and Epidemiology, Hanoi, Vietnam"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria","family":"del Carmen Parquet","sequence":"additional","affiliation":[{"name":"Department of Virology, Institute of Tropical Medicine, Nagasaki University, Sakamoto-machi 1-12-4, Nagasaki City 852-8523, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Futoshi","family":"Hasebe","sequence":"additional","affiliation":[{"name":"Department of Virology, Institute of Tropical Medicine, Nagasaki University, Sakamoto-machi 1-12-4, Nagasaki City 852-8523, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kouichi","family":"Morita","sequence":"additional","affiliation":[{"name":"Department of Virology, Institute of Tropical Medicine, Nagasaki University, Sakamoto-machi 1-12-4, Nagasaki City 852-8523, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"345","reference":[{"key":"R1","doi-asserted-by":"crossref","first-page":"255","DOI":"10.7883\/yoken1952.23.255","article-title":"Transoceanic flight of mosquitoes on the Northwest Pacific","volume":"23","author":"Asahina","year":"1970","journal-title":"Jpn J Med Sci Biol"},{"key":"R2","doi-asserted-by":"crossref","first-page":"333","DOI":"10.7601\/mez.37.333","article-title":"Ecological studies on the overwintering of mosquitoes, especially of Culex tritaeniorhynchus Giles in Osaka prefecture","volume":"37","author":"Buei","year":"1986","journal-title":"Jap J Sanit Zool"},{"key":"R3","doi-asserted-by":"crossref","first-page":"165","DOI":"10.1603\/0022-2585-40.2.165","article-title":"Population structure and dispersal of the freshwater mosquitoes Culex annulirostris and Culex palpalis (Diptera: Culicidae) in Papua New Guinea and northern Australia","volume":"40","author":"Chapman","year":"2003","journal-title":"J Med Entomol"},{"key":"R4","doi-asserted-by":"crossref","first-page":"181","DOI":"10.1016\/S0168-1923(97)00040-3","article-title":"Atmospheric influences on light-trap catches of the brown planthopper rice pest","volume":"88","author":"Crummay","year":"1997","journal-title":"Agric For Meteorol"},{"key":"R5","first-page":"125","article-title":"Studies on Japanese encephalitis virus infection of reptiles.
