Conservation of O157 LEE operons in a set of 24 EHEC 2 strains.

	LEE1 (9)^a	LEE2 (6)	LEE3 (7)	LEE5 (3)	LEE4 (8)
Human^b	8.8 ± 0.6	3.1 ± 1.7	4.8 ± 1.1	1.0 ± 0.0	4.4 ± 0.5
Animal^c	3.2 ± 1.2	0.6 ± 0.9	2.7 ± 0.9	0.1 ± 0.2	3.8 ± 0.9

a. The number of genes in each operon is given in parentheses.

b. Refers to the 10 human isolates in the top cluster of the dendrogram in the LEE image in Figure 5, not including O55:H7. Values represent average number of genes in an operon, with standard deviation.

c. Refers to the 11 animal and 3 human isolates in the bottom cluster of the dendrogram in the LEE image in Figure 5. Values represent average number of genes in an operon, with standard deviation.
