Presence of variable regions. Heatmap showing the presence and absence of variable chromosomal loci among 38 poultry strains and 21 non-poultry strains. Each column represents a different strain and each row represents a different chromosomal locus. Coloured sections represent a positive hit for that strain, grey represents a partial match (not entire locus but a single gene) and white is no match. Colours represent clade designation of a strains with pathogenic clade 1A (red), pathogenic clade 1B (pink) and pathogenic clade 2 (orange) while non-pathogenic clade 1 (dark green) and non-pathogenic clade 2 (light green). Non-poultry strains are coloured blue
