Core genome SNP phylogeny from community-acquired (n = 30) and indeterminate (n = 8) (“CD”), and nosocomial (“N”) C. difficile isolates (n = 33) was constructed as described in Fig. 2 using C. difficile 630 genome (NC_009089) as the reference. This tree was midpoint rooted based on the long genetic distance present between the majority of isolates and four nosocomial isolates (N09, N11, N04, N21). The bootstrap support values for all branches are 100
