Objective:To survey the current prevalence strain of wild measles virus in Jiangsu Province. Methods:In May 2005,the throat swab samples of the suspected measles patients in hospital and measles outbreak spot were collected,and inoculated into B95a cell derived from EB virus. Strains of wild measles virus were gottern. Results:RT-PCR and the sequence analysis of its product suggested that these 58 strains of measles viruses should belong to the H1 genotype of the eighth genetic group of wild measles virus. Conclusion:The genotype of wild measles virus isolated from Jiangsu province was the same as the dominant genotype prevalence in China.
