Table 4. Statistical values and absolute abundance of the 4 operational taxonomic units (OTUs) with significant differential abundance in pigs displaying the genotype associated with Staphylococcus aureus non-carriage (AA), as compared to the other two genotypes (AG or GG).

The degree of differential abundance is represented by log2 fold change (logFC), which indicates a positive or negative interaction (logFC >0 or <0) of the specified OTU in pigs with the AG or GG genotypes.

OTU	Abundance	logFC	p-Value	Adjusted p-Value
Pasteurella multocida	3012	3.24	4.45e-04	0.02600
Unclassified Klebsiella	3412	3.37	6.53e-04	0.02860
Unclassified Lachnospiraceae a	1006	-1.25	4.04e-04	0.02600
Unclassified Porphyromonadaceae	955	-2.69	6.11e-06	0.00107
