A History of the Development of Brucella Vaccines

Immunogencity of HSA-L7/L12 (Brucella abortus Ribosomal Protein) in an Animal Model

Background: The immunogenic Brucella abortus ribosomal protein L7/L12 is a promising candidate antigen for the development of subunit vaccines against brucellosis. Objective: This study was aimed to evaluate the protection of recombinant Human Serum Albumin (HAS)-L7/L12 fusion protein in Balb/c mice. Methods: The amplified L7/L12 gene was cloned in pYHSA5 vector, pYHSA5-L7/L12 construct was tra...

B and T-Cell Epitope Prediction of the OMP25 Antigen for Developing Brucella melitensis Vaccines for Sheep

Brucellosis, produced by Brucella species, is a disease that causes severe economic losses for livestock farms worldwide Due to serious economic and medical consequences of this disease, many efforts have been made to prevent the infection through the use of recombinant vaccines based on Brucella outer membrane protein (OMP) antigens. In the present study, a wide range of on-line prediction sof...

Evaluation of biochemical differences and Immunological effects of LPS and Lipid A extracted from Brucella strains

Background: The intrinsic heterogeneity determination in Brucella Lipopolysaccharide (LPS) is important for explaining its chemicalnature and biological behavior. This is significant for practical purposes, since LPS is the most relevant antigen during infectionand vaccination.Objectives: The purpose of the present study was to compare biochemical and immunological differences of LPS and lipid ...

Immunogenicity evaluation of plasmids encoding Brucella melitensis Omp25 and Omp31 antigens in BALB/c mice

Objective(s): Vaccination is one of the most effective means to protect humans and animals against brucellosis. Live attenuated Brucella vaccines are considered effective in animals but they may be potentially infectious to humans, so it is vital to improve the immunoprotective effects and safety of vaccines against Brucella. This study was designed to evaluate the immunogenicity of DNA vaccine...
