| epidemiological features of dengue and chikungunya infections in burma. | a serological survey for antibody to dengue and chikungunya was carried out in all 14 divisions and states and 2 border towns in burma during 1973-74. dengue hi antibody prevalence rate of less than 10% was observed in arakan and shan states, 10 to 30% in the irrawaddy, pegu, mandalay divisions and kachin, mon and karen states, 31 to 60% in sagaing division, and over 60% in rangoon, magwe and tenasserim divisions. similarly, chikungunya hi antibody prevalence rate of less than 10% was observed i ... | 1975 | 126493 |
| isolation of dengue type 3 from mosquitoes in rangoon. | a virus was isolated in suckling mice from aedes aegypti collected from rangoon area, during the month of july 1969. the virus was identified as a member of group b arbovirus dengue type 3, by means of its ability to agglutinate goose erythrocyte at ph 6.6, haemagglutination inhibition and complement fixation tests, and its growth characteristics in aedes albopictus cell cultures. the isolated dengue type 3 virus differs slightly from the indian dengue type 3 virus in its ability to produce haem ... | 1976 | 140463 |
| the effect of temperature and humidity on dengue virus propagation in aedes aegypti mosquitos. | the effect of temperature and relative humidity on dengue virus propagation in the mosquito as one of the possible contributing factors to dengue hemorrhagic fever (dhf) outbreaks was studied. ae. aegypti mosquitos were reared under standard conditions and inoculated intrathoracically with dengue virus. virus propagation in the mosquitos was determined at the temperature and relative humidity of all 3 seasons of yangon and for the simulated temperature and relative humidity of singapore. the vir ... | 1998 | 9886113 |
| diverse dengue type 2 virus populations contain recombinant and both parental viruses in a single mosquito host. | envelope (e) protein genes sampled from populations of dengue 2 (den-2) virus in individual aedes aegypti mosquitoes and in serum from dengue patients were copied to cdna, cloned, and sequenced. the nucleotide sequences of the e genes in more than 70% of the clones differed from the consensus sequence for the corresponding virus population at up to 11 sites, and 24 of the 94 clones contained at least one stop codon. virus populations recovered up to 2 years apart yielded clones with similar poly ... | 2003 | 12634407 |
