  • a Strains include 11 invasive isolates (prefix “DE,” National Reference Laboratory for Meningococci) and 17 carriage isolates (prefix “α,” Bavarian carriage study [4]; prefix “γ,” Sangerhausen carriage study [11]; strain 10115V3B, Burkina Faso [7]). cnl, capsule null locus (3); *, not serogroup and serogenogroup B, C, W-135, and Y, as determined by slide agglutination and specific PCR, respectively.

  • b Allele assignment was achieved by comparison with the PorA database at www.neisseria.org .
