Summary of molecular typing and serogroups of Neisseria meningitidis isolates, Niger, 2015*

Serogroup No. isolates ST/CC PorA† PorB† FetA† NadA‡ NhbA§ FHbp¶ gyrA§ penA§ rpoB§
C 81 ST-10217/NA P1.21–15,16 3–463 1–7 Not present 798 27/A106 2 22 1
W 14 ST-11/CC11 P1.5,2 2–2 1–1 2/3.6 96 9/B45 4 1 9
W 6 ST-11/CC11 P1.5,2 2–277 1–84 2/3.6 96 9/B45 4 1 9
*ST and CC are derived from multilocus sequence typing. CC, clonal complex; NA, not assigned; ST, sequence type.
†PorA, PorB, and FetA are typed according to their respective variable regions.
‡NadA is categorized by Novartis conventions of variant and peptide identifier.
§The alleles for gyrA, penA, and rpoB are identified by PubMLST DNA allele identifiers ( NhbA is identified by PubMLST peptide identifier.
¶FHbp is identified by the PubMLST peptide identifier and the Pfizer peptide identifier (subfamilies A and B). Assignment of Pfizer peptide identifier is pending for peptide 841.
