Fig. 3From: Whole genome analysis reveals the diversity and evolutionary relationships between necrotic enteritis-causing strains of Clostridium perfringensPCA on the pan-matrix. Each dot marks a genome in the first two principal components of the pan-matrix. Strains are coloured by clade designation and disease-causing capability. Shapes represent; triangle, netB positive from diseased birds; squares, netB negative poultry isolates; circle, non-poultry netB negative isolateBack to article page
