  1. Simpson's index of diversity (SID) with 95% confidence interval for individual and combined typing methods based on analysis of 123 Map isolates originating from Scotland (n = 48) and mainland Europe (n = 75) abcde Non-overlapping 95% confidence intervals are considered significantly different [55] and are indicated by different superscripts.
