From: Comparative genomics of Helicobacter pullorum from different countries
Differences in the number of genes in H. pullorum from different sources. The yellow circle represents the source of human (2 strains), the blue circle represents the source of chicken meat (4 strains), and the pink circle represents the source of contents (faces, caecum and liver, 17 strains). The middle common region is the core genes. The digit indicates the number of genes
