Comparative motility assays for C. difficile strains. The motility of strain 630 was compared to that of both recent and historic 027 ribotypes, R20291, BI-16 and CD196; M120 was the non-motile control. Strains were inoculated into 0.05% BHI agar and incubated for 24 hours in an anaerobe chamber. The motility is visualized as stalactite projections.
