Figure 1.

Genetic environment of chromosomal resistance genes found in S. Derby isolated from human clinical samples and food samples in Spain. (A). Genetic organization of the SGI1-variant, using LSP 138/08 as a model. (B). Comparison of the genetic context of fosA7.3 in LSP 82/16 (used as a model) and LSP 25/16. The alignments were created with Easyfig BLASTn. The gray shading between regions reflects nucleotide sequence identities according to the scale shown at the right lower corner of the figure. Genes are represented by arrows pointing to the direction of transcription. Genes with similar functions are shown in the same color. Color code: yellow, DNA replication; brown, conjugal transfer; blue, genes involved in DNA mobility; red, resistance genes; grey, other functions; white, hypothetical proteins.
