  • Title: Immunological specificity of monoclonal antibodies to Chlamydia psittaci ovine abortion strain.
    Author: Puy H, Fuentes V, Eb F, Orfila J.
    Journal: Immunol Lett; 1990 Jan; 23(3):217-21. PubMed ID: 2307492.
    Abstract:
    Fifty-one monoclonal antibodies were prepared by two different techniques against Chlamydia psittaci strain A22 isolated from an ovine abortion. These antibodies were tested for reactivity by the indirect immunofluorescent antibody technique with eleven reference Chlamydia strains (nine C. psittaci, one Chlamydia trachomatis and one Chlamydia pneumoniae). Four classes of specificity were recognized for monoclonal antibodies: genus, species, subspecies and type specificity. The type-specific monoclonal antibodies were non-reactive with ovine arthritis isolates. Twenty monoclonal antibodies were specific for two mammalian strains: ovine abortion A22 and K mouse. Some monoclonal antibodies were reactive with C. pneumoniae strains and non-reactive with C. trachomatis strains. All these monoclonal antibodies were very useful for improving the diagnosis of chlamydial infection, the antigenic analysis and the serotyping of C. psittaci.
