Sumario:Detection of Shiga toxins (Stx) is important for accurate diagnosis of Enterohemorrhagic Escherichia coli infection. In this study, we quantitatively analyzed Stx protein in nine patients’ stool during an outbreak that occurred in Japan. Highly sensitive immunoassay (bead enzyme-linked immunosorbent assay (bead-ELISA)) revealed that the concentrations of toxins in stool of patients ranged from 0.71 to 10.44 ng/mL for Stx1 and 2.75 to 51.61 ng/mL for Stx2. To our knowledge, this is the first report that reveals the range of Stx protein concentrations in human stools.
