Fig. 1From: Whole-genome sequencing to explore nosocomial transmission and virulence in neonatal methicillin-susceptible Staphylococcus aureus bacteremiaMinimum spanning tree, based on the core genome of 104 S. aureus isolates. Colours indicate the classical MLST sequence types (ST). Twelve cgMLST clusters containing at least two isolates with a maximum of eleven allelic differences are indicated with a grey backgroundBack to article page
