Comparison of Delmée and Polish serogroup-specific Clostridium difficile strains.

In this study we compared Delmée and Polish serogroup-specific Clostridium difficile strains by slide agglutination, observation of flagella and SDS-PAGE protein patterns. Among Delmée serogroup specific strains we observed flagella in groups A, D and K. Among Polish serogroup-specific Clostridium difficile strains we did not observe flagella. The Polish serogroup-specific strains gave different protein patterns compared to Delmée strains. SDS-PAGE protein pattern analyses of Polish serogroup-specific strains divide these strains into 3 groups: 71, 88 and third embracing 18, 27, 70, 72, and 89.
