  1. MMHD: mucohaemorrhagic diarrhea, IG: intragastric, Bhyo: Brachyspira hyodysenteriae (strains G44 or D19), Bhamp: B. hampsonii (strain 30446).
  2. aIncidence values are given frequency and as percentage (in parenthesis).
  3. bIncubation, duration, and proportionate duration of MMHD values are given as median of pigs that developed MMHD.
