Fig. 9From: Whole genome analysis reveals the diversity and evolutionary relationships between necrotic enteritis-causing strains of Clostridium perfringensCore genome phylogeny. Tree of maximum likelihood based on single nucleotide polymorphisms in the core chromosome of C. perfringens. Dark red and light red squares represent Pathogenic strains of C. perfringens clades 1 2 respectively while green triangles and diamonds represent non-pathogenic strains in clades 3 and 4 respectively.
