Fig. 2From: Differences between the global transcriptomes of Salmonella enterica serovars Dublin and Cerro infecting bovine epithelial cellsThe relative expression of genes in two pathogenicity islands, SPI-1 and SPI-4, of S. Dublin strains compared with S. Cerro strains during interaction with bovine epithelial cells. SPIs are scaled against each other. Each horizontal arrow represents a gene to scale within an SPI. The color of each arrow represents relative expression level in the S. Dublin strains compared with the S. Cerro strains while they were associated with bovine epithelial cellsBack to article page
