Fecal consistency scores, culture results and fecal concentration of “Brachyspira hampsonii” strain 30599 following inoculation. Fecal consistency scores (line, left ordinate: 0 = formed, normal; 1 = soft, wet cement consistency; 2 = runny or watery; 3 = mucoid diarrhea; or 4 = bloody diarrhea), semi-quantitative fecal culture score (red bars, left ordinate: 0 = negative; 1 = less than 10 colonies/1° streak; 2 = less than 10 colonies/2° streak; 3 = less than 10 colonies/3°streak; 4 = less than 10 colonies/4° streak), and strain 30599 DNA concentration in feces (triangles, right ordinate; upside down triangles indicate DNQ) are shown. Days post-inoculation are shown on the abscissa. ND = no data. Pig IDs are indicated in the upper left corner of each panel.
