Mapping of virulence determinants in S. Heidelberg. Heat map showing virulence factors identified in Salmonella ser. Heidelberg strains under this study. X axis represents sample name based on geographical origin of isolates. Y axis represents virulence gene names. Categories of virulence factors were grouped in to 5 groups. Group legend: 1. Fimbrial adherence determinants, 2. Macrophage inducible genes, Mg Uptake, and Non Fimbrial adherence determinants, 3. Secretion system, 4. Stress protein, Toxin, Two component system. A detailed description of predicted virulence data is available in Additional file 2: Table S2A, B. Color bar represents percentage sequence identity
