Pre‐Clinical Development of Two DNA Vaccines Encoding MrkA of Klebsiella pneumoniae: Effect of Plasmid Backbone on Immunogenicity and Protective Efficacy Against Sepsis

Microbial Biotechnology, Volume 19, Issue 8, August 2026.
Pre‐clinical development of two DNA vaccines encoding the MrkA fimbrial subunit of Klebsiella pneumoniae using different plasmid backbones: pVAX1 (commercial) and PLASMIVAX (with additional CpG motifs). Both DNA vaccine candidates expressed the antigen in eukaryotic cells but differed in their immunogenicity and protective efficacy against sepsis in ...

Hepatitis B virus genotype, HBsAg mutations and co-infection with HCV in occult HBV infection [PDF]

, 2011
Background: The association between mutations in the hepatitis B surface antigen (HBsAg) gene and the occurrence of occult HBV (OBI) in patients has not been studied adequately to determine if the two are correlated.

OCCULT HEPATITIS B VIRUS INFECTION AMONG BLOOD DONORS WITH ANTIBODIES TO HEPATITIS B CORE ANTIGEN [PDF]

Acta Medica Iranica, 2008
Diagnosis of hepatitis B is routinely based on of serological assay of hepatitis B surface antigen (HBsAg). Occult hepatitis B virus (HBV) infection is generally defined as the detection of HBV -DNA in the serum or tissues of subjects who have negative ...

Molecular analysis of hepatitis B virus (HBV) in an HIV co-infected patient with reactivation of occult HBV infection following discontinuation of lamivudine-including antiretroviral therapy

BMC Infectious Diseases, 2011
Background Occult hepatitis B virus (HBV) infection (OBI) is characterized by HBV DNA persistence even though the pattern of serological markers indicates an otherwise resolved HBV infection.
