From: Patterns of antimicrobial resistance in Salmonella isolates from fattening pigs in Spain
Hierarchical clusters using the binary antimicrobial susceptibility testing results of seven antimicrobials among 1,154 Salmonella isolates from pigs collected through the Spanish Veterinary Antimicrobial Resistance Surveillance Network programme between 2001 and 2013 (left: the proportion of isolates resistant to seven antimicrobials; right: the composition of serotypes in each of the clusters). Cluster 0 shows the serotype distribution of all isolates in the dataset (D_am7). Only serotypes accounting for ≥5% of the isolates in each particular cluster are shown in the graph
