FIG. 1.

Hybridization patterns of DIG-labeled 16S rRNA gene probes with Southern-blotted EcoRI restriction fragments of DNA from strains of all 11 repeatedly observed ribotype profiles. DIG-labeled HindIII restriction fragments were used as markers. Lanes B, C, D, and E, ribotype group I, ribotype profiles 1, 2, 3, and 4, respectively; lanes G, H, and I, ribotype group II, ribotype profiles 5, 6, and 7, respectively; lanes K, L, M, and N, ribotype group III, ribotype profiles 8, 9, 10, and 11, respectively; lanes A, F, J, and O, marker DNA. The numbers on the left are in base pairs.
