The genetic diversity of
<jats:italic>porB</jats:italic>
genes from meningococcal isolates characterized as serotype 22 was investigated by gene sequencing. This procedure identified seven distinct
<jats:italic>porB</jats:italic>
sequences, demonstrating variation in the PorB protein recognized by the serotype 22 monoclonal antibody. This is consistent with the genetic heterogeneity of serotype 22 meningococci reported previously.
