title: [Possible diagnosis of Pseudomonas aeruginosa infection by an immunoenzyme method using pyoimmunogen as the antigen].
abstract: The possibility of detecting P. aeruginosa antibodies in patients by means of indirect solid-phase EIA techniques is shown. This assay is carried out with the use of reagents produced in the USSR: polystyrene assay plates manufactured by the Lenigrad Medpolymer Works are used as carriers, P. aeruginosa vaccine (pyoimmunogen) obtained under semi-industrial conditions at the Mechnikov Central Research Institute for Vaccines and Sera is used as antigenic complex and the commercial preparation produced by the Gamaleia Research Institute of Epidemiology and Microbiology serves as conjugate. The studies have revealed that in 95% of cases the level of antibodies in the sera of patients with acute destructive pneumonia accompanied by pleural empyema, abscesses of internal organs and acute hematogenic osteomyelitis is essentially higher than the level of "normal" antibodies in healthy donors from whom biologically confirmed P. aeruginosa cultures can be isolated. In the groups of patients with similar nosological forms of diseases caused by other infective agents such difference in antibody titers is not detected. These results suggest that the detection of antibodies to P. aeruginosa in patients' sera by means of EIA can be used as an additional test for the diagnosis of P. aeruginosa infections.
