Amino acid differences between Malaysian Chikungunya strains of Asian and East/Central/South African genotypes.

Amino acid differences are reported following alignment of sequences obtained in this study from the Bagan Panchor strains MY/06/37348 and MY/06/37350 (Asian genotype), and the Johor strains MY/08/065 and MY/08/068 (ECSA genotype). The first amino acid named is found in the Asian strains, while the second amino acid is found in the ECSA strains. Differences at sites reported to be mosquito adaptation determinants in other alphaviruses are underlined.
