Frequency of S. Typhimurium subtype prevalence generated by CRISPR-MVLST and PFGE. Pie charts showing the number of distinct subtypes defined by a) CRISPR-MVLST and b) PFGE among 86 S. Typhimurium isolates. The most frequent TSTs or PFGE patterns observed are indicated. .0003 and .0146 represent PFGE profiles JPXX01.0003 and JPXX01.0146, respectively. The number of distinct subtypes defined by each method is listed in parenthesis and the discriminatory power (D) is listed below.
