TABLE 3.
BURST analysis of reference STs combined with STs obtained from year 1999 invasive study isolates
Ancestor ST based on BURST analysis of STs found in study isolates and reference strains.
Ancestor ST found in study isolates for the expanded lineage when the BURST analysis was expanded to all known STs.
Ancestor ST for the expanded lineage when the BURST analysis was expanded to all known STs; however, the ST was not encountered in study or reference isolates.
This ST was chosen as a reference sequence because of the unsurpassed number of SLVs or DLVs within the CC but is not ancestral based on BURST analysis. The ancestor ST was not identifiable within a BURST analysis expanded to study isolates and reference strains. When the BURST analysis was expanded to all known STs, this merged two study CCs into one.
When the BURST analysis was expanded to all known STs, these two STs were still the only members of the CC.
Reference strain only.
BURST analysis restricted to study and reference isolates only.
Still only member of lineage upon BURST analysis of all known STs.
Solid lines depict SLVs, and dotted lines depict DLVs.
Only listed for those with associations different from those depicted in columns two to four from our results.
