Spearman correlations data (p- and rho-values) for analysis of severity of SPES scores: (1) the quantification of A. pleuropneumoniae and M. hyopneumoniae were correlated with the macroscopic lesions of pleurisy score 2; (2) the quantifications of G. parasuis and S. suis were correlated with the macroscopic lesions of pleurisy score 3; and (3) the quantifications of M. hyopneumoniae and P. multocida and M. hyopneumoniae and S. suis were correlated with the macroscopic lesions of pleurisy score 4.

Pleurisy Lesion Severity	Interaction	Spearman’s Correlation	p-Value
Score 2	A. pleuropneumoniae and M. hyopneumoniae	R = 0.42	p = 0.04
Score 3	G. parasuis and S. suis	R = 0.45	p = 0.04
Score 4	M. hyopneumoniae and P. multocida	R = 0.58	p = 0.03
	M. hyopneumoniae and S. suis	R = 0.63	p = 0.02
