[The determination of optimal regimens for producing Klebsiella antigenic erythrocytic immunoreagents].

The optimum conditions for obtaining sensitive K- and D-serovar-specific Klebsiella antigenic erythrocyte diagnosticum have been established. The methods of choice are sensitization with lipopolysaccharide antigens at pH 5.0 and in a neutral medium at a temperature of 45 degrees C for an hour. The reagents thus obtained have proved to be specific when tested in the passive hemagglutination test with antisera to Shigella, Salmonella and Escherichia.
