Safranin O-stained antigen microagglutination test for detection of brucella antibodies.
A microagglutination test was compared with a standard tube agglutination test for the detection of brucella antibodies. Advantages of the microagglutination test were that it required less time to perform, had a shorter incubation period, and used less antigen.
متن کاملMicroagglutination test for detecting and measuring serum agglutinins of Francisella tularensis.
A microagglutination method utilizing stained antigen for detecting and measuring serum agglutinins against Francisella tularensis is described. The microagglutination and standard tube agglutination techniques were demonstrated to be comparable in sensitivity and specificity. Advantages of the micro method are rapidity and ease of performance, economy of reagents and, in particular, ease of in...
متن کاملCharacterization of the O-antigen polymerase (Wzy) of Francisella tularensis.
The O-antigen polymerase of gram-negative bacteria has been difficult to characterize. Herein we report the biochemical and functional characterization of the protein product (Wzy) of the gene annotated as the putative O-antigen polymerase, which is located in the O-antigen biosynthetic locus of Francisella tularensis. In silico analysis (homology searching, hydropathy plotting, and codon usage...
متن کاملIdentification, Characterization and Immunogenicity of an O-Antigen Capsular Polysaccharide of Francisella tularensis
Capsular polysaccharides are important factors in bacterial pathogenesis and have been the target of a number of successful vaccines. Francisella tularensis has been considered to express a capsular antigen but none has been isolated or characterized. We have developed a monoclonal antibody, 11B7, which recognizes the capsular polysaccharide of F. tularensis migrating on Western blot as a diffu...
متن کاملRole of the wbt locus of Francisella tularensis in lipopolysaccharide O-antigen biogenesis and pathogenicity.
Francisella tularensis is a highly infectious bacterial pathogen, responsible for the zoonotic disease tularemia. We screened a bank of transposon insertion mutants of F. tularensis subsp. holarctica LVS for colony morphology alterations and selected a mutant with a transposon insertion in wbtA, the first gene of the predicted lipopolysaccharide O-antigen gene cluster. Inactivation of wbtA led ...
