  • ↵a Analysis of the chromosomal locationsopB, sopD, or sopE2 was performed by Southern blotting (S), PCR (P), or both techniques (S/P). Primers and probes are described in Table 1, Fig. 1, and Materials and Methods. The bar marked 0.1 represents the relative genetic distance as adopted from reference 3. *, with SARC13, the PCR product (primers 7 and 8) was only 6 kb, while SARC strains 1, 2, 5 to 11, 15, and 16 yielded an 8.5-kb product.
