Abstract: Objective To detect the genotype of hepatitis C virus(HCV)in chronic hepatitis C(CHC)infection patients using gene sequence method and observe the distributive characteristic of HCV genotype in Hubei.Methods A total of 447 HCV-RNA-positive plasma samples were collected from chronic hepatitis C patients in Infectious Diseases Department of Renmin Hospital of Wuhan University from February 2013 to July 2015.Then NS5B region gene sequence of HCV genome were de-tected by Sanger sequencing method and compared with HCV genotype in NCBI genebank database for analyzing HCV geno-type.Results A total of 11 kinds of genotypes were detected,including genotypes 1a,1b,2a,3a,3b,6a,6b,1b/2a,1b/2k,6a/1b and 6d/6k,respectively.Detection cases of various genotypes were respectively 7 cases (1.57%),325 cases (72.71%),67 cases (14.99%),7 cases (1.57%),20 cases (4.47%),14 cases (3.13%),2 cases (0.45%),2 cases (0.45%),1 case (0.22%),1 case (0.22%)and 1 case (0.22%).Conclusion Genotype 1b was the major type of HCV-RNA genotype,fol-lowed by 2a,also other genotypes existed,which prompted that the prevalence of HCV genotype was diversity in Hubei.
