The numbers in parentheses reflect the adjustment in assignment that took place after the Quellung reaction, which was reperformed to address inconsistencies with the multibead assay results. For instance, seven isolates were originally labeled to be 6B. However, a repeat Quellung assay showed one isolate to have a different serotype. Thus, only six isolates were truly 6B.
