Expression in Escherichia coli of a cloned DNA sequence encoding the pre-S2 region of hepatitis B virus [PDF]

, 1985
A DNA sequence encoding the entire pre-S2 region (amino acids 120-174; serotype ayw) of human hepatitis B virus envelope protein has been inserted into the lacZ gene of the plasmid pSKS105 yielding a recombinant, pWS3.

A common HLA-DPA1 variant is associated with hepatitis B virus infection but fails to distinguish active from inactive Caucasian carriers [PDF]

, 2012
Background and Aims: Chronic infection with the hepatitis B virus (HBV) is a major health issue worldwide. Recently, single nucleotide polymorphisms (SNPs) within the human leukocyte antigen (HLA)-DP locus were identified to be associated with HBV ...

Serum HBeAg and HBV DNA levels are not always proportional and only high levels of HBeAg most likely correlate with high levels of HBV DNA

Medicine, 2017
This study aimed to investigate the correlation between quantitative hepatitis B e antigen (HBeAg) and hepatitis B virus (HBV) DNA levels, and to determine whether semiquantitative measurement of HBeAg can indicate the extent of HBV replication in HBeAg ...

Correlation between hepatitis B G1896A precore mutations and HBeAg in chronic HBV patients [PDF]

, 2015
Background: Hepatitis B virus (HBV) infection is an important health concern worldwide, with critical outcomes. Hepatitis B e antigen (HBeAg) negative chronic hepatitis B is frequently caused by a mutation (G1896A) in the hepatitis B virus (HBV) precore (

Xenosurveillance reflects traditional sampling techniques for the identification of human pathogens: A comparative study in West Africa [PDF]

, 2018
BACKGROUND: Novel surveillance strategies are needed to detect the rapid and continuous emergence of infectious disease agents. Ideally, new sampling strategies should be simple to implement, technologically uncomplicated, and applicable to areas where ...

Occult Hepatitis B Virus Infection in Chacma Baboons, South Africa

Emerging Infectious Diseases, 2013
During previous studies of susceptibility to hepatitis B virus (HBV) infection, HBV DNA was detected in 2/6 wild-caught baboons. In the present study, HBV DNA was amplified from 15/69 wild-caught baboons. All animals were negative for HBV surface antigen

HBV DNA Quantitation Using Real-time PCR

Annals of Laboratory Medicine, 2006
Accurate measurement of the concentration of hepatitis B virus (HBV) DNA in clinical samples is important for the appropriate treatment of patients and evaluation of their therapeutic responses. In addition, the concentration of HBV DNA in the serum of patients with chronic HBV infection has a very broad range.
