A rapid method for Proteus serologic typing is suggested, based on Soviet commercial diagnostic adsorbed type sera. The rapid system involves replacing two-staged typing with one-staged, making use of polyvalent sera constructed by uniting 8-9 type sera according to the suggested schemes. O- and H-antigens are types in accordance with special tables. Fifteen O-antigens and 4 H-antigens, whose total incidence among Proteus clinical strains is under 2 percent, cannot be typed with the use of this system. The suggested rapid system is suggested as a rapid simple method for typing Proteus clinical strains in intricate epidemiologic situations.
The authors present literature and personal data on the intragenera O-antigenic relations of the strains of a collection of bacteria belonging to Providencia genus, including standard strains of 53 serological O-groups whose antigenic interrelations were studied serologically in the tests of agglutination and adsorption of agglutinins. Experimental results confirmed the presence of unilateral relations by the O-antigen between the serological groups 01-021, 03-021 and bilateral relations between the serological groups 01-03; there were also revealed relations by the O-antigens between the serological groups 09-036, 014-023, 018-035, 039-053, and 039-027 of a unilateral character. The data obtained added information to the antigenic structure of Providencia and were of significance for the preparation of diagnostic O-sera of Providencia.
