Significantly different (P < 0.05) group means within each column are indicated by different superscript letters (A or B).
Possible scores for interstitial pneumonia ranged from 0 (normal) to 6 (severe diffuse interstitial pneumonia).
The mean cumulative value from seven lymphoid tissues (tonsil, spleen, and five lymph nodes) is reported (possible range, 0 to 9) and includes scores for lymphoid depletion (possible range, 0 to 3), inflammation (possible range, 0 to 3), and the amount of PCV2 (possible range, 0 to 3). Possible cumulative scores for overall severity included normal (score of 0), mild (score range, 1 to 3), moderate (range, 4 to 6), and severe (range, 7 to 9).
