Production and Characterization of Monoclonal Antibodies against Brucella abortus S (99) Surface Antigens
By immunizing mice with killed whole bacterial cells of Brucella abortus S (99), a panel of six hybridomas producing monoclonal antibodies (mAb) specific for the surface antigens of this bacterium were produced. ELISA was used to screen the hybridoma supernatants. Immunoblots of the cell extract indicated that three mAb were specific for S-LPS (Ba-1, Ba-2, Ba-3) and three others were reactive w...
متن کاملProtection of BALB/c mice against pathogenic Brucella abortus and Brucella melitensis by vaccination with recombinant Omp16
Objective(s): Prevention of the globally spread zoonotic infection, brucellosis which affects an extensive range of hosts is still challenging researchers. There are no approved vaccines for the prevention of human disease and those used for animal brucellosis have adverse properties, which limit their application. We investigated the immunological and protective effec...
متن کاملSerological confirmation of Brucella abortus and Yersinia enterocolitica O:9 O-antigens by monoclonal antibodies.
Murine monoclonal antibodies that bind the O-antigens of Yersinia enterocolitica serotype O:9 and Brucella abortus 1119-3 were generated after immunization of BALB/c mice with killed, whole cells. Highly purified lipopolysaccharide preparations from each organism were used to screen for antigen-specific antibodies. Immunization with B. abortus cells induced 56 antigen-specific hybrids, and 10 o...
متن کاملPolysaccharide Specific Monoclonal Antibodies Provide Passive Protection against Intranasal Challenge with Burkholderia pseudomallei
Burkholderia pseudomallei is a Gram-negative bacillus that is the causative agent of melioidosis. The bacterium is inherently resistant to many antibiotics and mortality rates remain high in endemic areas. The lipopolysaccharide (LPS) and capsular polysaccharide (CPS) are two surface-associated antigens that contribute to pathogenesis. We previously developed two monoclonal antibodies (mAbs) sp...
متن کاملEffectiveness of natural and synthetic complexes of porin and O polysaccharide as vaccines against Brucella abortus in mice.
A single vaccination of mice with a complex of porin and smooth lipopolysaccharide (porin-S-LPS) extracted from virulent Brucella abortus 2308 provided significant protection (P less than 0.01 to P less than 0.001) against challenge with the same strain, equivalent to that achieved by vaccination with living attenuated B. abortus 19. The porin-S-LPS vaccine given without adjuvant or in several ...
