Production of a species specific monoclonal antibody against a 56-kDa Mycobacterium marinum antigen which is potentially useful in culture identification

A monoclonal antibody (MoAb) designated 1H11 has been produced against a 56-kDa antigen from Mycobacterium marinum. This MoAb has been shown to be species specific by both enzyme-linked immunosorbent assay and Western blot. The relationship of this 56 kDa to other known mycobacterial antigens is currently under investigation. MoAb 1H11 recognised bacilli taken from cultures by both immunofluorescence and immunoperoxidase staining. This MoAb 1H11 may provide a simple method for rapid identification of M. marinum from cultures of clinical isolates. (C) 2001 Federation of European Microbiological Societies.
