Multilocus sequencing typing (MLST) of encapsulated and nonencapsulated Haemophilus influenzae isolates. MLST was performed on a subset of encapsulated isolates (n = 44) from the evaluation set, including all type a and type b isolates (n = 33). All major genetic lineages (indicated by colors), except the least common lineage of Hia (ST4-related), of encapsulated H. influenzae were represented in the collection, including the 2 more common lineages of Hia and all 3 lineages of Hib.

Figure 2. Multilocus sequencing typing (MLST) of encapsulated and nonencapsulated Haemophilus influenzae isolates. MLST was performed on a subset of encapsulated isolates (n = 44) from the evaluation set, including all type a and type b isolates (n = 33). All major genetic lineages (indicated by colors), except the least common lineage of Hia (ST4-related), of encapsulated H. influenzae were represented in the collection, including the 2 more common lineages of Hia and all 3 lineages of Hib. An isolate typed by PCR as Hif (KR1130) with a nonexpressed pseudogene cap locus was also included. This isolate was not part of the established Hif lineage, and was initially suspected to be an outlier on the basis of differences from other Hif in matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) mass spectra. All capsule transformants (n = 4) were ST47 (same as the parental strain Rd) (30,31) and were part of the Hid lineage. Nontypeable H. influenzae (NTHi; no color) included as reference isolates in the capsule typing databases (n = 28) were included in the analysis. NTHi in the evaluation set misclassified as type e (n = 5, indicated by asterisks) were also included. These isolates belonged to 3 separate genetic lineages, all related to the Hie lineage. Isolates included as references in MALDI-TOF mass spectrometry databases are indicated by arrows and numbers (1 for isolates in the original database and 2 for isolates added during supplementation of the database). Scale bar indicates nucleotide substitutions per site. Hia, H. influenzae type a; Hib, H. influenzae type b; Hic, H. influenzae type c; Hid, H. influenzae type d; Hie, H. influenzae type e; Hif, H. influenzae type f; ST, sequence type.
