The Analysis on Hepatitis B Virus Genotypes in Some Regious of Hangzhou / 医学研究杂志

ABSTRACT

Objective To investigate the distribution of hepatitis B virus genotypes in Hangzhou area and preliminarily identify and evaluate the applied characteristics of oligonuleotides(oligo)microarray for genotyping hepatitis B virus(HBV).Methods HBV PCR products were hybridized with oligonucleotide probes,which were prestablized on the chip.The hybridized results were colorized.According to the hybridization signal and the corresponding probe sequence,HBV genotype was determined.Results Of the 106 HBV DNA positive patients 37(34.91%)were genotype B,and 69(65.09%)were genotype C,No genotype A,E and F were found in the studied subjects.Conclusions HBV genotype B and C exsited in Hangzhou No HBV genotype A,D,E and F were found in the studied subjects.We should take further investigation for HBV genotypes by enlarging study population.The advantages of this assay are sensitive accurate,fast and economical when using it for HBV genotype test comparing with other relative methods.
