    Using the reverse transcription-polymerase chain reaction (RT-PCR) and direct sequencing, capsid protein and non-structural protein 1 (nsP1) regions of Sagiyama virus and eight Getah virus strains were analysed. The viruses were isolated from Malaysia and various areas of Japan over a period of 30 years. Based on the available published sequence data, oligonucleotide primers were designed for RT-PCR and the sequences were determined. Our findings showed that though there were differences in the nucleotide sequences in the nsP1 region, there was 100% amino acid homology. On the other hand, in the capsid region, the nucleotide differences caused a major difference in the amino acid sequence. Therefore, the difference in the capsid region is one of the useful markers in the genetic classification between Sagiyama virus and strains of Getah virus, and might be responsible for the serological difference in complement fixation test. The genomic differences among the Getah virus strains are due to time factor rather than geographical distribution.
