Heatmap showing hierarchical clustering of antimicrobial resistance genes found in multidrug-resistant Escherichia coli isolated from bovine mastitis in Brazil. The columns represent genes, and the rows represent sample name and ST (sequence type from Multilocus Sequence Typing, MLST). Dark blue cells indicate gene presence, and light blue its absence. Hierarchical clustering was performed using the software Morpheus (https://software.broadinstitute.org/morpheus), binary distance matrix, and Pearson’s correlation
