主 题：Oligonucleotide chip Hepatitis B virus Genotype
摘 要：AIM： TO determine the genotype distribution of hepatitis B virus （HBV） with a newly oligonucleotide chip assay among the HBV carriers in Eastern China. METHODS： An assay using oligonucleotide chip was developed for detection of HBV genotypes in serum samples from HBV DNA-positive patients in Eastern China. This method is based on the principle of reverse hybridization with Cy5-labeled amplicons hybridizing to type-specific oligonucleotide probes that are immobilized on slides. The results of 80 randomly chosen sera were confirmed by direct sequencing. RESULTS： HBV genotype B, C and mixed genotype were detected in 400 serum samples, accounting for 8.3% （n = 33）, 83.2% （n = 333）, and 8.5% （n = 34）, respectively. The evaluation of the oligonucleotide assay showed 100% concordance with the amplicon phylogenetic analysis except 9 mixed genotype infections undetected by sequencing. CONCLUSION： The study indicates that HBV genotype C and B prevail in the Eastern China. It is suggested that the oligonucleotide chip is a reliable and convenient tool for the detection of HBV genotyping.
