title: [The production of a latex immunoglobulin conjugate for the diagnosis of Gardnerella vaginalis].
abstract: To obtain an anti-Gadnerella vaginalis latex globulin, specific immunosera to reference strain (ATCC 14018) and to a clinical isolation strain pool were produced. These immunosera were characterized using PAGE-SDS and immunoblotting where a close antigenic relation between the clinical isolation strains and the reference strain was observed. The latex globulin conjugates obtained from these 2 immunosera were evaluated in vitro with a resulting level of detection of 10 ufc/mL of Gardnerella vaginalis. These two conjugates were also evaluated in clinical samples and compared with the 6 vaginalis culture and the criteria considered for diagnosing bacterial vaginosis. The anti-strain pool (II) latex globulin conjugate turned out to be more sensitive and specific than anti-G. vaginalis ATCC strain (I) latex globulin.
