Summary: | Evaluate prevalence of genetic variants of hepatitis B, viruses in population of various regions of Uzbekistan with hepatitis of various genesis and different severity levels of liver fibrosis and cirrhosis.
Blood plasma and liverbiopsy from 39 patients with different severity levels of liver fibrosis and cirrhosis served as study material. Genotyping based on direct sequencing of Pre-S1/Pre-S2/S HBV DNAregion was applied.
Hepatitis B virus was detected in 32 samples ofthe 39 provided, frequency of occurrence - 82%, respectively. Phylogenetic analysis has shown, that only genotype D was detected among the examined,patients, hepatitis B virus subtype D1 predominated (84.38%) compared with D2 (3.12%) and.D3 (12.5%) subtypes.
Large-scale sequencing of HBV in, Central Asia will allow to evaluate routes of transmission and time of evolutionary separation or virus isolates. Understanding the epidemiology of the infectious process is important for development of programs for prophylaxis and therapy of the infection. |
