AFLP profiles of C. diphtheriae produced by primer PstI-G. Lanes 1, 4, 7, 10, 13, 16, and 19, 100-bp molecular weight standard (with sizes indicated on the left). The remaining lanes show AFLP profiles of the following strains: C93/46 (lane 2), C95/66 (lane 3), C95/87 (lane 5), C93/69 (lane 6), C93/78 (lane 8), C93/266 (lane 9), C95/115 (lane 11), C93/181 (lane 12), C95/59 (lane 14), C93/45 (lane 15), C93/274 (lane 17), and C93/277 (lane 18). AFLP types are given above each lane, and ribotype designations are given at the bottom of each lane.
