title: [Flagellar antigens of E. coli serologically interrlelated to H40, 41 and H41, 42, 43 flagellar antigens of Citrobacter. New H-antigeny E. coli i Citrobacter].
abstract: The authors confirmed the reference of the test strains H13 (P6c) and H22 (A231a) of the international collection of E. coli to Citrobacter; their antigenic formula was established. As shown, strains P6c possessed a variety of the H-antigen which was not described in Citrobacter earlier, designated as H41a, 97. Three types of flagellar antigens characterized by the presence of an interrelationship with the partial factor H41 of the flagellar Citrobacter antigens were revealed in E. coli; the partial composition of H-antigenic components common for E. coli and Citrobacter was studied. Two of three new varieties of the E. coli H-antigen revealed was characterized by a cross correlation and a relation to the standard H19 E. coli antigen. The strain with the third variety of the H-antigen was capable of forming the H-antigenic mutants which acquired the antigenic component identical to the standard H16 E. coli antigen. E. coli strain is recommended for the replacement of the strain P6c in the International collection of E. coli.
