Map of the α-hly region of plasmid pEO5 (FM180012). The positions of PCR-primers used for investigation of strains with plasmid and chromosomally inherited α-hly genes are indicated as leaders carrying the primer designations (Table 2). Regulatory sequences inside the hlyR gene (A, B and OPS) are shown as filled ballons. "phly152" is a stretch of non-coding DNA showing strong homology to corresponding regions in the α-hly plasmid pHly152.
