Table 4 Group mean microscopic L. intracellularis lesion score

From: Bacillus pumilus probiotic feed supplementation mitigates Lawsonia intracellularis shedding and lesions

Group Mean lesion score (range: 0–9) Lesion severity distribution
Normal Mild Moderate Severe
T01-LAW 4.3 ± 0.9A 1 3 3 3
T02-LAW 3.3 ± 0.7A 1 8 0 1
T03-LAW 3.3 ± 0.5A 1 6 3 0
VAC-LAW 4.9 ± 1.1A 1 4 1 4
NEG-CONTROL 0.0 ± 0.0B 10 0 0 0
POS-CONTROL 5.6 ± 0.8A 2 5 2 11
  1. The score is based on a combination of intestinal hyperplasia, inflammation and L. intracellularis antigen and distribution of the pigs in each group into normal (score 0), mild (score 1, 2 or 3), moderate (score 4, 5 or 6) or severe (score 7, 8 or 9).
  2. aDifferent superscripts (A,B) indicate a significant different weight gain (P < 0.05) among groups during a time period.
