[Characteristics of the serologic properties of bacteria of the genus Moraxella]

Antigenic relationships between different Moraxella species and closely related bacteria were examined in agglutination (AT), indirect immunofluorescence (IIF), double gel immunodiffusion tests, and counter-current immunoelectrophoresis with experimentally obtained antisera. Specificities of commercial antibody reagents, manufactured by Abbott, USA, intended for enzyme immunoassay diagnosis of gonorrhea and urogenital chlamydia infections, were assessed. Results of donor blood serum examinations helped establish AT and IIF diagnostic titres to be used in serologic diagnosis of infections induced by various Moraxella species.
