FIG. 7.
PCR analyses of the region between the cpe gene and downstream IS1470-like sequences. (A) PCR product amplified from specified type A isolates using primers for cpe gene sequences and sequences present in IS1470-like sequences of F4969, which generate an ∼2.2-kbp product (arrow at right) with DNA from F4969. Numbers on the left indicate migration of molecular size markers. (B) PCR products amplified from specified type A isolates using primers specific for internal IS1470-like sequences. This reaction generated the expected 0.9-kbp product from F4969 DNA (arrow). Numbers on the left indicate migration of molecular size markers.
