Abstract：
:The polymerase chain reaction (PCR) and restriction enzyme analysis were used to develop a rapid and simple procedure for identifying geographic subgroups of dengue virus within serotypes for epidemiologic investigations. The entire structural protein region of dengue viruses was amplified and the products were digested with the endonucleases AluI or DdeI. By comparing the restriction fragment length polymorphisms (RFLPs), we recognized dengue-2 and dengue-3 subgroups that corresponded to those previously determined by oligonucleotide fingerprinting or genomic sequencing. This procedure can be performed in 2 days without the use of radioisotopes, and results can be interpreted without computer analysis. For those analyses which require only subgroup affiliations, this is a useful tool for rapidly screening multiple virus isolates.
