Fig. 1From: Prevalence, antibiotic resistance, virulence and genetic diversity of Staphylococcus aureus isolated from bulk tank milk samples of U.S. dairy herdsSNP-based phylogenetic tree of S. aureus isolates from bulk tank milk from 189 U.S. dairy farms. This tree includes 70,978 SNPs from 117 isolates, using reference genome NCTC 8324. Isolates are labeled by ST, and the different colors represent different geographic regionsBack to article page
