Population Structure of Invasive Streptococcus pneumoniae in the Netherlands in the Pre-Vaccination Era Assessed by MLVA and Capsular Sequence Typing
Figure 1
The frequency of the various alleles present in the 8 BOX loci used for MLVA.
The graphs display the frequency of each allele (number of repeats) for each BOX locus. The Simpson's Diversity Index is indicated for each BOX locus. The number 99 was assigned if no PCR product could be amplified.
