Antimicrobial resistance pattern in a Escherichia coli (148), b Enterococcus faecalis (34) and c enterococci other than E. faecalis (112) recovered from 37 Spanish pig farms. The isolates were clustered according to their antimicrobial resistance pattern using the unweighted pair group method with arithmetic mean (UPGMA) as hierarchical clustering method. For this purpose, the pheatmap package (Kolde, 2019) was used. Streptogramins antimicrobial class was excluded from the E. faecalis clustering due to its intrinsic resistance
