Amplification of viral RNA for the detection of dengue types 1 and 2 virus

J Infect. 1992 Jan;24(1):23-9. doi: 10.1016/0163-4453(92)90842-t.


In vitro DNA amplification by means of the polymerase chain reaction (PCR) was used to amplify dengue types 1 and 2 viral genomes in cultured cells and in the serum of persons infected with dengue virus. Results of the present investigation suggest that the PCR method is type-specific in detecting dengue virus and has a detection sensitivity of less than 100 plaque-forming units (pfu) for both serotypes of the virus. The PCR method may be useful for detecting and typing dengue virus in clinical and epidemiological specimens.
