title: Use of the Mycoplasma hominis 102-116 kD proteins as antigen in an enzyme-linked immunosorbent assay.
abstract: Mycoplasma hominis surface structures involved in human immune response and in the pathogenesis of this bacterial infection are inadequately defined. Attempts have been made to identify M. hominis surface proteins, to determine the antigenicity of these polypeptides, and to examine antigens which could lead to the development of species-specific diagnostic tests. By means of Western blotting, using a pool of sera from patients with culturally proven vaginal infection, most antigens recognized were surface exposed. Among these proteins, antigens of molecular weights between 102 and 116 kD were most consistently revealed. These polypeptides were recovered by electroelution and assayed in an IgG-ELISA. The electroeluted antigen specificity was examined by ELISA and immunoblotting with different mycoplasma species. Electroeluted proteins may be effective and specific for establishing a reliable diagnosis test.
