mosquito collection in endemic areas of japanese encephalitis in hokkaido, japan. | a study was conducted during 1985 and 1986 to evaluate the roles of mosquito species as possible vectors of japanese encephalitis (je) virus in hokkaido. the number of culex tritaeniorhynchus was very low among the four pig farms where outbreaks of abortion caused by je virus were observed in swine populations. at one farm near sapporo, only one cx. tritaeniorhynchus was found among a total of 510 mosquitoes collected during the survey period from july to october 1985, even when je virus activit ... | 1989 | 2575185 |

ecological studies of japanese encephalitis virus in hokkaido: interepidemic outbreaks of swine abortion and evidence for the virus to overwinter locally. | outbreaks of abortion and stillbirth caused by japanese encephalitis virus were observed in swine populations in hokkaido in 1984 and 1985. two strains of japanese encephalitis virus were isolated from aborted fetuses in different outbreaks, and the antigenic types of the strains found to be different from nakayama and jagar-01. the outbreak of 1985 was in early june, the interepidemic period of japanese encephalitis in northern temperate zones. a seroepidemiological survey carried out from 1984 ... | 1988 | 2833128 |

epidemiology of tick-borne encephalitis in japan. | a tick-borne encephalitis (tbe) patient has not been reported for many years in japan although a serological survey of domestic animal sera suggested the presence of tbe foci in hokkaido, the northern island of japan. in october 1993 in hokkaido, a severe encephalitis case in a farm wife was diagnosed as tick-borne encephalitis. serological examination of paired sera showed a rise of neutralization (nt) antibody titer to russian spring summer encephalitis virus. a sero-epizootiological survey of ... | 1998 | 9611678 |
[current status of japanese encephalitis in japan]. | japanese encephalitis (je) cases confirmed by serological and/or virological tests, and clinically typical fatal je cases have been collected using individual report cards in japan since 1965. a total of 324 confirmed cases (male: 167, female: 157) reported between 1982 and 1996 were analyzed. annual incidence of je cases was less than one hundred cases from 1982 to 1991, and less than 10 cases after 1992. age distribution of the patients was: 0-9 years old, 43 cases (13%); 10-39 years old, 30 c ... | 1999 | 10213985 |
antibodies to flaviviruses in wild ducks captured in hokkaido, japan: risk assessment of invasive flaviviruses. | recently, the distribution of japanese encephalitis virus (jev) and west nile virus (wnv) has expanded into new territories. the invasion of wnv into japan is of great concern. the migration of birds is suggested to be involved in the expanded distribution of these flaviviruses. in this study, 92 wild ducks--20 anas poecilorhyncha (migratory breeders), 50 anas platyrhynchos (undetermined), 16 anas acuta (winter visitors), and 6 anas penelope (winter visitors)--were captured in autumn of 2005 and ... | 2009 | 19514809 |
detection of antibodies against japanese encephalitis virus in raccoons, raccoon dogs and wild boars in japan. | japanese encephalitis virus (jev) infects numerous animal species including humans, horses and pigs. in this study, antibodies against jev in feral raccoons (procyon lotor), wild boars (sus scrofa) and raccoon dogs (nyctereutes procyonoides) in japan were examined. the results showed that 40.7% (22 out of 54), 64.5% (40 out of 62), 69.1% (47 out of 68) and 0% (0 out of 20) of raccoons in hyogo, osaka, wakayama and hokkaido, respectively, had virus-neutralizing antibodies against jev. in addition ... | 2009 | 19721354 |
antibodies to h5 subtype avian influenza virus and japanese encephalitis virus in northern pintails (anas acuta) sampled in japan. | blood samples from 105 northern pintails (anas acuta) captured on hokkaido, japan were tested for antibodies to avian influenza virus (aiv), japanese encephalitis virus (jev), and west nile virus (wnv) to assess possible involvement of this species in the spread of economically important and potentially zoonotic pathogens. antibodies to aiv were detected in 64 of 105 samples (61%). of the 64 positives, 95% and 81% inhibited agglutination of two different h5 aiv antigens (h5n1 and h5n9), respecti ... | 2013 | 24059097 |
