A − Median values of the microscopic lymphoid lesion scores in pigs from PCV-2a (
), PCV-2b (
), PCV-2d (
), PCV-2e (
), and negative control (
) groups. B − Median values of the microscopic lung lesion scores in pigs from PCV-2a (
), PCV-2b (
), PCV-2d (
), PCV-2e (
), and negative control (
) groups. C − Median values of the microscopic lymphoid lesion scores in pigs from PCV-2a/PRRSV (
), PCV-2b/PRRSV (
), PCV-2d/PRRSV (
), PCV-2e/PRRSV (
), PRRSV (
), and negative control (
) groups. D − Median values of the microscopic lung lesion scores in pigs from PCV-2a/PRRSV (
), PCV-2b/PRRSV (
), PCV-2d/PRRSV (
), PCV-2e/PRRSV (
), PRRSV (
), and negative control (
) groups. Variation is expressed as the interquartile range (IQR). Different superscripts (a, b, c, and d) indicate significant (P < 0.05) difference among either single-infected or dual-infected groups.
