a Principal component analysis (PCA) of 44 Japanese B. cereus group isolates. The PCA was performed using the FactoMineR and Factoshiny packages (version 1.42) in R (version 3.5.2) software based on the presence/absence of virulence-associated genes determined by BTyper. Principal components 1 (Dim1) and 2 (Dim2) are plotted on the x and y axes, respectively. Each dot corresponds to an isolate. Isolates are clustered and colored by origin as animal (orange), food poisoning (dark green), hospital (blue green), and soil (purple), with all the isolates within a colored circle belonging to the same cluster. The variables factor map was generated according to cos2 > 0.7. b Scree plot of eigenvalue variance and the variables according to their contributions to principal components 1 (Dim1) and 2 (Dim2). Asterisks indicate P < 0.01. Variables significantly associated with a given principal component were calculated using the FactoMineR package (version 1.42)
