  • a Correlation with serotypes defined by MAbs.

  • b Nomenclature for the alleles already appointed in the Web site http://neisseria.org/nm/typing/porB. GenBank accession numbers only for the new allelic variants found in the present study are indicated in parentheses.

  • c That is, the number of strains in each VR combination.

  • d That is, the number of strains showing a specific allelic variant which were not recognized by MAbs (NT strains with MAbs).

  • e That is, the number of strains showing that specific allelic variant which were recognized by MAbs (typeable strains with MAbs). The serotype obtained by MAbs is given in parentheses.
