Eight genotypes of hepatitis B virus (A–H) are currently recognized, and subgenotypes have
recently been described in four of these genotypes (A, B, C and F). The genotypes show a …

Bedbugs are brown and flat hematophagous insects. The 2 cosmopolite species, Cimex
lectularius and Cimex hemipterus, feed on humans and/or domestic animals, and recent …

Hepatitis B virus (HBV) is divided into nine genotypes, A to I. Currently, it remains unclear
how the individual genotypes contribute to the estimated 250 million chronic HBV infections …

Of approximately 360 million people in the world chronically infected with hepatitis B virus
(HBV), 65 million reside in Africa. Thus, Africa, with 12% of the world's population, carries …

Background Chronic infection with hepatitis B virus (HBV) is associated with a high lifetime
risk of developing hepatocellular carcinoma (HCC) and cirrhosis of the liver. Purpose To …

Hepatitis B virus (HBV) is one of the most widely distributed viruses that infect humankind.
Distinct clinical and virological characteristics of the HBV‐infection have been reported in …

We conducted a phylogenetic analysis of 19 hepatitis B virus strains from Laos that
belonged to 2 subgenotypes of a new genotype I. This emerging new genotype likely …

The genetic variability of hepatitis B virus (HBV) represents a challenge for the sensitivity of
immunologic and molecular based assays. Based on sequence divergence in the entire …

Using phylogenetic analysis and pairwise comparison of 670 complete hepatitis B virus
(HBV) genomes, we demonstrated that nucleotide divergence greater than 7.5% can be …

Background Occult hepatitis B virus infection (OBI) characterized by the absence of
detectable HBsAg remains a potential threat in blood safety. We investigated the actual …
