| a survey of dengue viral infection in aedes aegypti and aedes albopictus from re-epidemic areas in the north of thailand using nucleic acid sequence based amplification assay. | immature stages of aedes aegypti and ae. albopictus were collected from 17 dengue re-epidemic areas in chiang mai and lampang provinces, in the north of thailand. they were reared to adults and tested for dengue viral rna by a nucleic acid sequence based amplification assay (nasba). of a total of 9,825 ae. aegypti and 150 ae. albopictus examined, none of them were found positive for the virus, suggesting that transovarial transmission may be very low in the vector populations and may not play a ... | 2007 | 17877218 |
| the effect of dengue virus infection on the clinical sequelae of japanese encephalitis: a one year follow-up study in thailand. | in order to determine if prior dengue virus infection reduces the severity of japanese encephalitis (je), we examined 127 patients hospitalized during the 1970 je epidemic in the chiangmai and lampang valleys of northern thailand. patients were studied during the first 30 days after onset of je; 120 of these patients were examined one year later for residual neurologic sequelae. about 21% of patients had serological evidence of a prior dengue virus infection. morbidity and mortality in patients ... | 1975 | 176736 |
| frequency of pyrethroid resistance in aedes aegypti and aedes albopictus (diptera: culicidae) in thailand. | thirty-two aedes aegypti populations collected throughout thailand and five populations of aedes albopictus from southern thailand were subjected to standard who contact bioassays to assess susceptibility to three commonly used synthetic pyrethroids: permethrin, deltamethrin, and lambda-cyhalothrin. a wide degree of physiological response to permethrin was detected in ae. aegypti, ranging from 56.5% survival (lampang, northern thailand) to only 4% (kalasin in northeastern and phuket in southern ... | 2011 | 21635659 |
