title: [Analysis of genetic characteristics of wild-type measles viruses in Jilin Province 2005].
abstract: OBJECTIVE
  To investigate the know gene types of main wild type measles virus strains and take measures to control measles in Jilin Province.
  
  
  METHODS
  Genetic characterization of 9 measles viruses isolated from 72 throat swabs or urine specimens of measles patients using CDW(150) cells line was studied in Jilin Province in 2005.
  
  
  RESULTS
  Sequence analysis of 450 nucleotides of COOH-terminal of nucleoprotein (N) genes of 9 isolates indicated that all were members of H(1) genotype, in which there are 7 strains of H1a and 2 strains of H1b, the H1a subgroup differed from H1b by 2.0% approximately 3.5% at the nucleotide level in the COOH-terminal of the N gene.
  
  
  CONCLUSIONS
  The H(1) genotype of wild-type measles viruses should be the main epidemic strain and main pathogen that caused measles outbreaks and sporadic cases in Jilin Province.
