FIG. 2.
Nucleotide sequences of elyA and hlyA amplicons. elyA represents strains of serovars O157:H7 (28), O111:H− (29), and O157:H−, O103:H2, O103:H−, O26:H11, and O26:H−; strain 1114/93 was serovar Ont:H−; strain 18-6/95 was serovar Orough:H−; strain 849/95 was serovar O89:H−; strain 6780/96 was serovar Ont:H19; and hlyA represents strains used by Kuhnert et al. (18) and strain E57 (serovar O138:K81:H−). Dashes represent nucleotides identical to elyA. Asterisks symbolize gaps in the aligned nucleotide sequence.
