In vitro hemolytic capacity of B. hyodysenteriae strains used in this study. Hemolysis is represented by the mean value of absorption at 450 nm after incubation of red blood cell suspension with supernatant of the different B. hyodysenteriae identifiable strains. PC, positive control; NC, negative control. Significant differences between B. hyodysenteriae identifiable strains and reference strain B204 are indicated,* P < 0.01.
