Figure 2. MLST loci map for Clostridioides difficile strains DQ/RT591 and BI/RT027 in study of C. difficile at 2 US Veteran Affairs long-term care facilities and their affiliated acute care facilities. The 2 strains are 4 SNPs apart. Scale bar indicates nucleotide substitutions per variable site of loci. MLST, multilocus sequence typing; SNP, single-nucleotide polymorphism; ST, sequence type.
