摘要
The complete nucleotide sequence of the measles virus strain IMB-1,which was isolated in China,was determined.As in other measles viruses,its genome is 15,894 nucleotides in length and encodes six proteins.The full-length nucleotide sequence of the IMB-1 isolate differed from vaccine strains (including wild-type Edmonston strain) by 4%-5% at the nucleotide sequence level.This isolate has amino acid variations over the full genome,including in the hemagglutinin and fusion genes.This report is the first to describe the full-length genome of a genotype H1 strain and provide an overview of the diversity of genetic characteristics of a circulating measles virus.
