Evidence of an Exponential Decay Pattern of the Hepatitis Delta Virus Evolution Rate and Fluctuations in Quasispecies Complexity in Long-Term Studies of Chronic Delta Infection. [PDF]

PLoS ONE, 2016
Chronic HDV infection can cause a severe form of viral hepatitis for which there is no specific treatment. Characterization of the hepatitis B or C viral quasispecies has provided insight into treatment failure and disease recurrence following liver ...

Correlation Between Quantitative Hepatitis B Surface Antigen and Hepatitis B Virus Deoxyribonucleic Acid Levels in Hepatitis B e Antigen-Positive and Hepatitis B e AntigenNegative Chronic Hepatitis B Patients

Turkish Journal of Gastroenterology, 2020
Background: This study aimed to analyze the relationship between quantitative hepatitis B surface antigen and hepatitis B virus deoxyribonucleic acid in hepatitis B e antigen-positive and hepatitis B e antigen-negative chronic hepatitis B patients and to determine the best cut-off value for quantitative hepatitis B surface antigen to predict high ...

Prevalence of viral hepatitis B markers among blood donors in the Republic of Guinea

Вопросы вирусологии, 2022
Introduction. The problem of transfusion safety in relation to parenteral viral hepatitis still remains relevant. Viral hepatitis B (HB) remains the most common viral infection transmitted through transfusion procedures.

e antigen in acute hepatitis B. [PDF]

BMJ, 1976
To examine the association between e antigen and hepatitis-B surface antigen (HBs Ag) we studied 90 inpatients with acute viral hepatitis type B. e Antigen was present in 24 of the patients; these patients had detectable levels of HBs Ag for significantly longer than the 66 with no e antigen in their serum.

Comparison of hepatitis B viral loads and viral antigen levels in child-bearing age women with and without pregnancy

BMC Pregnancy and Childbirth, 2018
Background Pregnancy is a unique physiological condition with the cellular immune functions compromised at some extents to allow the mature of growing fetus. Whether pregnancy may influence the replication of hepatitis B virus (HBV) is less studied.

Seroprevalence for Hepatitis E and Other Viral Hepatitides among Diverse Populations, Malawi

Emerging Infectious Diseases, 2015
Data on prevalence of hepatitis E virus (HEV) in Malawi is limited. We tested blood samples from HIV-uninfected and -infected populations of women and men enrolled in research studies in Malawi during 1989–2008 to determine the seroprevalence of HEV ...

Demonstration of the Immunogenicity of Hepatitis B Core Antigen in a Hepatitis B e Antigen Polypeptide (P19)

Journal of General Virology, 1981
The core of Dane particles, the presently accepted hepatitis B virus nucleocapsid, contains two polypeptides (P19 and P45) with the antigenicity of hepatitis B e antigen (HBeAg). The antigenicity of hepatitis B core antigen (HBcAg) was not detectable in either of them by the conventional in vitro assay methods, despite the fact that both of these ...

Hepatitis associated with hepatitis B virus in broilers

Journal of Integrative Agriculture, 2016
Infection by hepatitis B virus (HBV) results in acute and chronic liver damages in humans. Liver products of broilers as a primary food consumed in our daily life have a close connection with public health. The prevalence of the virus in livers and serum
