Identification of Moraxella bovis by using a monoclonal antibody to a lipopolysaccharide epitope.
نویسندگان
چکیده
A monoclonal antibody to the lipopolysaccharide of Moraxella bovis is described. In an indirect fluorescent-antibody test, this monoclonal antibody reacted with 39 of 39 strains of M. bovis tested and did not react with 26 nonfermenting gram-negative coccobacilli other than M. bovis. When used in an indirect fluorescent-antibody test, it proved useful for rapid and easy identification of M. bovis.

Characterization of hemolysin of Moraxella bovis using a hemolysis-neutralizing monoclonal antibody.
A concentrated bacterial culture supernatant from the hemolytic Moraxella bovis strain UQV 148NF was used to immunize mice and generate monoclonal antibodies (MAbs). One, MAb G3/D7, neutralized the hemolytic activity of M. bovis and recognized a 94-kDa protein by Western blot analysis in hemolytic M. bovis strains representing each of the different fimbrial serogroups. Exposure of corneal epith...
متن کاملProduction of Monoclonal Antibody against Prokaryotically Expressed G1 Protein of Bovine Ephemeral Fever Virus
Epitope-G1 of bovine ephemeral fever virus (BEFV) G glycoprotein has been genetically and antigenically conserved among various isolates of BEFV and only reacts with anti-BEFV neutralising antibodies. Therefore, it is a candidate antigen for development of the enzyme linked immunosorbent assay (ELISA) for serological identification bovine ephemeral fever (BEF)-infected animals. The aim of this ...
متن کاملProduction and Characterization of Murine Monoclonal Antibodies Recognizing Conformational and Linear Epitopes Localized on Human IgA2 Molecules
Background: There are two subclasses of human IgA (IgA1 and IgA2) that differ in antigenic properties and in chemical composition. The constant domains of α1 and α2 heavy chains have >95% sequence homology though major structural differences exist in the hinge region. Quantitation of IgA subclass levels depends on the availability of monoclonal antibodies (MAbs) specific for conserved conformat...

Background and Objective: Lipoarabinomannan mannesylated (ManLAm) is one of the lipoglycans which forms a considerable percent of Mycobacterium Bovis BCG’ cellular wall. Considering that generation of monoclonal antibody against ManLAM antigen has many applications, specifically, in order to design the diagnostic kit for rapid diagnosing of tuberculosis, so the main objective of this study wa...

Type 4 fimbriae have been identified on the cell surface of Actinobacillus pleuropneumoniae by electron microscopy and N-terminal sequencing analysis. A. pleuropneumoniae type 4 fimbrial subunit protein, purified from cell cultures and from outer membrane preparations, reacted with polyclonal antibody raised against type 4 fimbriae of Moraxella bovis on Western blots. N-terminal sequence analys...
