Complete Genomic Sequence of an Australian Sindbis Virus Isolated 44 Years Ago Reveals Unique Indels in the E2 and nsP3 Proteins.

ABSTRACT The complete genome sequence of a Sindbis virus (SINV) strain (SINV_AUS_1975_18953) isolated in Australia in 1975 from Culex annulirostris mosquitoes revealed unique deletions in amino acid positions 182 to 184 and 201 to 228 of the E2 envelope protein and multiple indels in the nonstructural protein 3 (nsP3).
