[A method of rapid indication of an antigen].

A simple and sensitive method for rapid detection of an antigen is offered. 0.025 ml of antiserum is placed on the slide, 0.025 ml of clarified extract containing the antigen added, and then 0.025 ml of intact 20.10(6) suspension of Kowan 1 Staphylococcus strain is added. When antigen-antibody complex is forming, staphylococcal cell aggregation starts. A staphylococcal reagent, manufactured by the Pasteur Research Institute of Epidemiology and Microbiology in Leningrad, may be employed, this making the method more available. The indication sensitivity is 0.2-1.25 mln cells per ml, this value depending on the bacterial species.

[Escherichia-erythrocyte diagnostic agents].

The conditions of a simple and practicable method for the preparation of effective antigenic nonprotein diagnosticums on the basis of water-phenol extracts of 23 Escherichia species have been developed. The method consists in heating the mixture of erythrocytes and the antigen in a boiling water bath for 60 minutes. The diagnosticums thus obtained are 16-30 times more sensitive in the passive hemagglutination test and 4-6 times more sensitive in the passive hemagglutination inhibition test than diagnosticums prepared with the use of tannin, rivanol, as well as by the common method for the preparation of nonprotein antigens. The minimum concentration of Escherichia cells detected in the passive hemagglutination inhibition test is 0.8-1.2 million cells/ml.
