Correction: Four Genotyping Schemes for Phylogenetic Analysis of Pseudomonas aeruginosa: Comparison of Their Congruence with Multi-Locus Sequence Typing.

Tables 1 and 2 are incorrectly switched. The table that appears as Table 1 should be Table 2, and the table that appears as Table 2 should be Table 1. The table titles appear in the correct order. Please see the correct Tables 1 and 2 here. The publisher apologizes for these errors.

Table 1

Number of genotypes, clonal complexes and singletons retrieved from the four genotyping schemes.

Typing methods	MLST	MLVA	PFGE	DiversiLab
Genotypes/types	67 STs	85 MTs	90 PFGE-types	61 DL-types
Clonal complexes/clonal groups	11	11	20	25
Singletons/unique patterns	39	49	70	36

Table 2

Simpson's index of diversity of the different typing methods.

Typing methods	No. of types	SID	95% CI
PFGE	90	0.989	(0.984–0.995)
MLVA	85	0.980	(0.970–0.991)
DL (cut-off 95%)	61	0.961	(0.946–0.977)
DL (cut-off 93%)	46	0.937	(0.915–0.958)
MLST	67	0.906	(0.860–0.951)
