Figure 4From: Characterization of Shiga toxin – producing Escherichia coli infections in beef feeder calves and the effectiveness of a prebiotic in alleviating Shiga toxin - producing Escherichia coli infectionsThe effect of the number of O157 Shiga toxin – producing Escherichia coli (STEC) involved in an infection on the amount of STEC shed by beef feeder calves fed diets containing 0 (control) or 14 g/[heifer•d] Celmanax®. The fecal samples were collected at day 0 and day 35. Mean values are shown (n = 28 for both treatments in spring; n = 30 for control treatments in summer; n = 31 for Celmanax® treatments in summer). The contribution of O157 STEC infections was scored as follows: 1 = one O157 STEC in the fecal sample; 2 = two O157 STECs in the fecal sample, 3 = greater than two O157 STECs in the fecal sample.Back to article page
