Objective:
To detect HBV DNA and its genotypes.
Methods:
The 6 isoforms of HBV DNA was detected out using of different probes by Polymerase Chain Reaction and Nucleic Acid hybridization.
Results:
Of 150 HBV DNA positive patients who lived in Shenzhen, 50 samples (33%) are type B, 36 samples (24%) are type C, 13 samples (9%) are type D, 3 samples is type F, 1 sample is type A, 48 samples (31%) are mixed type. The ALT value was significantly higher in genotype B than in genotype C. HBe positivity were higher in genotype B than genotype C. HBeAg positivity were higher in genotype C than in genotype B. There are not obvious relations between genotype and age or sex.
Conclusion:
In the detected samples, the major genotype of HBV DNA is type B, several are type C, D. The type E haven't been found. There are some relations between all kinds of genotypes and the severity of hepatitis B.
