FIG. 2.

Southern blot of EcoRI-digested genomic DNAs from L. monocytogenes serotype 4b strains with probe 1-4. Lane M, λ molecular size markers, as described in the legend for Fig. 1. RFLP pattern I, lanes 5, 11, 13, and 17 (presumably sporadic strains of serotype 4b, not associated with ECI or ECII); RFLP pattern II, ECI strains from Hawaii (lanes 3 and 4), Jalisco (lanes 7, 8, 9, and 12), and Nova Scotia (lanes 10 and 14); RFLP pattern III, ECII strains LM 20 (lane 1), LM 21 (lane 2), and LM 50, (lane 15); RFLP pattern IV, strains 267 (lane 6) and A2 (lane 16) (both serotype 4b and of unusual genotype).
