Volume 84, no. 1, p. 138–148, 2016, https://doi.org/10.1128/IAI.00977-15. Page 140: Figure 1 should appear as shown below. The figure has been revised so that, in each lane, loading controls are appropriately matched.
Page 140, Fig. 1 legend, lines 2 and 3: “…HCT-8 cells treated with Stx1 for zero minutes (C0) to 6 h. Lanes are labeled C (untreated), S1 (Stx1), or HI (heat-inactivated Stx1).” should read “…HCT-8 cells treated with Stx2 for zero minutes (C0) to 6 h. Lanes are labeled C (untreated), S (Stx2), or HI (heat-inactivated Stx2).”
Page 140, Fig. 1 legend, lines 7 and 8: “Stx1 and heat-inactivated Stx1” should read “Stx2 and heat-inactivated Stx2.”
Page 141, Fig. 2 legend, line 5: “samples treated with Stx1 (S) or StxAY77S,E167QB1 (M)” should read “samples treated with Stx2 (S) or StxAY77S,E167QB2 (M).”
Page 141, Fig. 2 legend, line 8: “Stx1” should read “Stx2.”
Page 142, Fig. 3 legend, line 2: “Stx1” should read “Stx2.”
