objective(s):brucellosis is a well-known domestic animal infectious disease, which is caused by brucella bacterium. groel antigen increases brucella survival and is one of the major antigens that stimulates the immune system. hence, the objective of the present study was cloning and bioinformatics analysis of groel gene. materials and methods: the full-length open reading frame of this gene was...

background: neisseria meningitidis, a life-threatening human pathogen with the potential to cause large epidemics, can be isolated from the nasopharynx of 5–15% of adults. the aim of the current study was to evaluate biophysical and biochemical properties and immunological aspects of chimeric acyl-carrier protein-macrophage infectivity potentiator protein-type iv pilus biogenesis protein antige...

mutations in the human hepatitis b virus (hbv) genome contribute to its escape from host immune surveillance and result in persistent infections. the aim of this study was to characterize the molecular variations of the surface gene and protein in chronically-infected patients from the southern part of iran. the  surface  genes  from  12  hbv  chronic  carriers  were  amplified, sequenced  and ...

Development of efficient peptide-based immunotherapy for shrimp allergy relies on the identification dominant T-cell epitopes its major allergen, tropomyosin. In this study, immunoinformatic tools, proliferation, cytokine release, IgG/IgE binding, and degranulation assays were used to identify characterize in Lit v 1 comparison with previously validated B-cell epitopes. The results showed that ...

abstract background: naturally occurred hepatitis b virus (hbv) with surface mutations in a variety of chronic hepatitis b (chb) patients who have received no vaccine or hbig bearing substitutions in surface protein, have been reported. objectives: current knowledge concerning the prevalence of these naturally occurring surface antigen mutations among iranian carriers is limited. patients and m...

Introduction: The Rubella virus has a worldwide occurrence and congenital syndromes are widely recognized as an emerging infection in several parts of the world. Miscarriage, perinatal mortality, stillbirth can develop pregnancy during first trimester. most frequent techniques for laboratory diagnosis IgM IgG-based serological detection methods. Such viral bacterial pathogen emphasizes developm...

Immunoglobulin molecules are folded in a way that assembles sequences from the variable regions of both the heavy and light chains into a surface feature (comprised of up to six complementarity-determining regions (CDRs)) that is complementary in shape to a surface structure on the antigen. These two surface features, the ‘paratope’ on the antibody and the ‘epitope’ on the antigen, may have a c...

Brucellosis is a well-known infection in domestic animals which caused by Brucella bacterium. Due toserious economic and medical consequences of this disease, various efforts have been made to prevent theinfection through the use of recombinant vaccines based on Brucella outer membrane protein (OMP)antigens. The objectives of the present study were cloning, sequencing and epitope prediction of ...
