[Identification of Vibrio cholerae serogroups O1 and O139 by monoclonal antibodies in the slide agglutination test].

ABSTRACT

The agglutinating properties of MCA-O1 of the IgG class and MCA-O139 of the IgM class towards epitopes of O-antigen of Vibrio cholerae O1 and accordingly Vibrio cholerae O139 were studied. The ascitic and cultural fluids by hybridomas F8G12 and D11 deposited in the specialized Collection of Cell Cultures of Vertebrates (Saint Petersburg) under RKKK (II) 386 D and RKKK (II) 674 D were the sources of monoclonal immunoglobulins. The advantage of diagnostic monoclonal immunoglobulins is that they are distinguished for strict specificity and their use in practical health care contributes to the higher specificity of a laboratory test for cholera and to its shorter performance.
