Summary
Hepatitis B virus (HBV) genotyping revealed genotypes B and C as the most prevalent. Coinfections with genotypes B and C or B and D were rare, with no gender association observed.
Area of Science:
- Virology
- Molecular Biology
- Genetics
Context:
- Hepatitis B virus (HBV) infection is a global health concern.
- Accurate HBV genotyping is crucial for understanding viral evolution and disease progression.
- Previous genotyping methods had limitations in reliability and scope.
Purpose:
- To develop and validate robust methods for HBV genotyping.
- To determine the prevalence and distribution of HBV genotypes in a specific cohort.
- To investigate potential associations between HBV genotypes and patient demographics.
Summary:
- Developed type-specific primers based on S gene nucleotide analysis for reliable HBV genotyping.
- Genotyped 238 HBV strains using PCR, identifying 159 (66.8%) as genotype B and 69 (28.9%) as genotype C.
- Found rare instances of mixed genotypes (B/C and B/D) and no association between HBV genotypes and patient gender.
Impact:
- Establishes effective HBV genotyping methodologies for clinical and research applications.
- Provides critical epidemiological data on HBV genotype distribution, particularly highlighting the dominance of genotypes B and C.
- Informs public health strategies and personalized treatment approaches for Hepatitis B.
