| pilot sero-epidemiological survey on japanese encephalitis in north-western burma. | a pilot sero-epidemiological survey of japanese encephalitis was carried out in three areas of north-western burma applying the hemagglutination-inhibition test. the existence of japanese encephalitis infection in these areas was confirmed and its incidences in these areas were estimated and compared graphically. | 1979 | 233227 |
| arbovirus infections in sarawak, october 1968--february 1970 tembusu and sindbis virus isolations from mosquitoes. | thirty isolations of tembusu virus and four of sindbis virus were obtained from approximately 280 000 mosquitoes collected between october 1968 and february 1970 in sarawak, particularly from k. tijirak, a land dyak village 19 miles south of kuching. twenty-two isolations of tembusu virus and two of sindbis virus were from culex tritaeniorhynchus; two of tembusu virus and two of sindbis virus came from culex gelidus. tembusu virus was active throughout the year at k. tijirak, the highest infecti ... | 1975 | 235907 |
| arbovirus infections in sarawak, october 1968-february 1970: getah virus isolations from mosquitoes. | 14 strains of getah virus were isolated from a variety of mosquito species collected in sarawak between october 1968 and february 1970. ten strains were isolated from c. tritaeniorhynchus 7 of them at k. tijirak. single strains were isolated from c. gelidus, c. pseudovishnui, m. bonneae/dives and aanopheles species. 6 of the isolates were obtained in october 1968 when japanese encephalitis, tembusu and sindbis viruses were also very active. the available evidence suggest that getah virus in sara ... | 1975 | 238314 |
| use of duck embryo cell cultures for the study of arbovirus reproduction. | duck embryo cell (dec) cultures were used for the study of arbovirus reproduction. high sensitivity of dec cultures to japanese encephalitis, west nile, tyuleniy, sakhalin and baku viruses was established. dec cultures are recommended for investigation of arbovirus reproduction. | 1975 | 241248 |

| neutralization tests for dengue and japanese encephalitis viruses by the focus reduction method using peroxidase-anti-peroxidase staining. | neutralization tests were made on 4 types of dengue (den) virus and japanese encephalitis (je) virus by incubation of serially diluted antisera and constant amounts of the viruses and then focus assay of surviving virus infectivity with peroxidase-anti-peroxidase (pap) staining. neutralization reactions were virtually completed in 2 hr on incubation of serum-virus mixtures at 28 c. a straight regression line was obtained on a probit chart by plotting the focus reduction rates at various dilution ... | 1978 | 383069 |

| geographic distribution of arbovirus antibodies in indigenous human populations in the indo-australian archipelago. | sera from lifetime residents in 16 localities of the indo-australian archipelago and adjacent areas were tested for hemagglutination-inhibition antibody against four alpha-viruses (sindbis, getah, chikungunya, and ross river) and for neutralizing antibody against six flaviviruses (dengue 2 and 3, japanese encephalitis, murray valley encephalitis, kunjin, and edge hill). mosquito collections were carried out in some of the localities to study vector relationships to distribution of the arbovirus ... | 1979 | 453438 |
| proteins specified by togaviruses in infected aedes albopictus (singh) mosquito cells. | yields of greater than 10(7) p.f.u./ml at 28 or 37 degrees c of the alphavirus sindbis and the flavivirus kunjin were obtained in the aedes albopictus (singh) cell line, the latent periods being 4 to 6 and 10 to 12 h, respectively. despite a high background of host protein synthesis, virtually all the virus-specified proteins of the flaviviruses kunjin, dengue-2 and japanese encephalitis were labelled and resolved by slab gel electrophoresis of infected and uninfected cell proteins. in contrast, ... | 1979 | 479844 |

| intracellular distribution of virus-specific rna in chick embryo cells infected with japanese encephalitis virus. | japanese encephalitis virus (jev) infected chick embryo (ce) cells were treated with 4 mug actinomycin d/ml and 5 mm-d-glucosamine at 2 or 3 h before harvesting. production of jev was not affected by the short-time treatment of these drugs. the radioactivity in virus-specific rna in the glucosamine-treated cells was a-parently higher than in non-treated cells. nuclear and cytoplasmic extracts were prepared from the jev-infected cells pulse-labelled with 3h-uridine at 15 h after infection. analys ... | 1977 | 556758 |
| polykaryocytosis induced by certain arboviruses in monolayers of bhk-21-528 cells. | multinucleated giant cell formation in a clone of bhk-21 cells, bhk-21-528, was tested with certain arboviruses. eleven out of 19 viruses tested, chikungunya, getah, sagiyama, sindbis, western equine encephalitis, st. louis encephalitis, japanese encephalitis, west nile, bunyamwera, germiston and california encephalitis virus induced cell fusion after infection. all cases where giant cells were observed during the experiments, involved the b type cell fusion (fusion from within). | 1977 | 557074 |
| association of virus specific replicative ribonucleic acid with nuclear membrane in chick embryo cells infected with japanese encephalitis virus. | using high resolution electron microscopic autoradiography and velocity sedimentation, rna synthesis was examined in chick embryo cells infected with japanese encephalitis virus (jev). rna was labelled with 3h-uridine for 5 min or 10 min at 15 h after infection in the presence of actinomycin d and d-glucosamine. microautoradiography showed significantly numbers of silver grains on the nuclear membranes of 5 min pulse-labelled thin cell sections. the rna species in membrane fractions obtained fro ... | 1978 | 564392 |
| critical evaluation of the role of immunization as an etiological factor of infantile spasms. | one hundred and ten cases of infantile spasms with detailed information about immunization available were selected as the masterial to evaluate the significance of immunization as an etiological factor of infantile spasms. in 80% of the cases, immunization could not be considered to have any relation with causation of infantile spasms, because 44 cases (40%) never had innoculations as yet, and other 44 cases (40%) had been immunized by some vaccines over one month before or after the onset of th ... | 1977 | 578294 |
