Abstract
On the basis of 8 new O and 11 new H antigens determined in 22 strains, the M. morganii antigenic schema was supplemented with 8 serogroups (O35-O42) and 13 serotypes. Four strains belonged to O groups described earlier and 2 strains contained new O antigens in combination with known O antigens. Known H antigens were present in 1 strain as a single factor and in 1 strain as combination of 2 factors. New H antigens were demonstrated in 5 serotypes in combination with known H antigens. Six out of the 22 isolates were classified into O group 35. Two isolates contained different B-type surface antigens; these factors were not related to Escherichia coli B antigens and, unlike the latter, their living suspension gave a higher titer agglutination in OK serum as compared to the boiled culture.
