We assessed the genetic diversity of 26 Neisseria
lactamica strains from epidemiologically related sources, i.e.,
groups of kindergartens and primary schools in three Bavarian towns, by the partial sequencing of the argF, rho, recA, and 16S
ribosomal genes. We found a total of 17 genotypes, of which 12 were
found only in one strain. The genotypes comprised 5 alleles of the
argF gene, 9 of rho, 8 of recA, and
10 of the 16S ribosomal DNA. Sequence analysis by determination of
homoplasy ratios and split decomposition analysis revealed abundant
recombination within N. lactamica.
