Application of monoclonal antibody for Riemerella anatipestifer in preparation of immune colloidal gold test paper

The invention belongs to the field of biotechnology and particularly relates to a monoclonal antibody for Riemerella anatipestifer and an application thereof. The monoclonal antibody 5G7 has a preservation number of CGMCC (China General Microbiological Culture Collection Center) No.5165. The invention also discloses an application of the monoclonal antibody in preparation of an immune colloidal gold test paper for detecting the Riemerella anatipestifer. According to the invention, the immune colloidal gold test paper can be used to not only detect cause of disease directly but also detect RA (Riemerella Anatipestifer) strains of different serotypes 1, 2, 3 and 11 at the same time, so that the immune colloidal gold test paper has higher application value.
