Intra- and inter-patient evolution of PVL-positive CC1 MSSA isolates responsible for outbreaks and sporadic infections. Neighbor-joining tree of 19 PVL-positive CC1 MSSA isolates that were implicated in outbreaks in a home for mentally disabled patients (outbreak 1) and in a prison (outbreak 2), and in recurrent infections in two patients (patient 1 and patient 2). The node numbers are bootstrap scores based on 100 repetitions. The scale represents the number of SNPs in 1,328 core genes.
