[Immunoenzyme method of diagnosing suppurative-septic complications due to Pseudomonas aeruginosa and Proteus]

Two test systems, based on the inhibition of the reaction of enzyme-labeled antibodies and on the indirect reaction of enzyme-labeled antibodies, have been developed with a view to diagnosing purulent and septic complications caused by P. aeruginosa and Proteus in accordance with the results of the determination of the corresponding microbial antigens and antibodies to these antigens in the patients' blood. An increase in the levels of P. aeruginosa and Proteus antigens during the first 3 days of the development of complications and in the titers of antibodies on days 7-10 indicates that the purulent septic complication is caused by the given infective agent. A high correlation of the results obtained by bacteriological and serological diagnostic methods has been observed.
