FIG. 2.
Genetic organization of the C. difficile CD5 tet(W) DNA region. The approximate extent and organization of the region are not necessarily to scale. ORFs and their orientation are represented by arrows: the tet(W) gene is designated by a gray arrow, whereas white arrows represent the three ORFs found in the DNA regions surrounding tet(W). Individual primers and their orientations are indicated by small black arrows.
