title: Immunologic characterization and specificity of three monoclonal antibodies against the 58-kilodalton protein of Legionella pneumophila.
abstract: Three monoclonal antibodies against the Legionella pneumophila 58-kDa protein were produced. By using immunoblot analysis, the percentages of reactivity against 47 serogroups of Legionella representing 29 species were determined to be 80.9, 87.2, and 95.6 for monoclonal antibodies GB5BE8, GB5AF6, and CA4AF5, respectively. Specificities obtained from testing 63 heterologous organisms representing 22 genera and 46 species were 90.7, 92.2, and 95.3% for monoclonal antibodies GB5BE8, GB5AF6, and CA4AF5, respectively. No single heterologous strain was reactive with all three monoclonal antibodies. These monoclonal antibodies successfully identified all 10 clinical isolates of Legionella examined in a dot blot assay and should be excellent reagents for use in genuswide diagnostic immunoassays.
