SUMMARY: The thermal stability of interspecies DNA duplexes is markedly increased by raising the incubation temperature. When the DNA reassociation reactions are carried out at 75 in 0.12 M-phosphate buffer the thermal denaturation temperature of the reassociated product is almost identical to that of the native DNA, indicating that only DNA segments of very similar nucleotide sequence are associating. The genus very clearly forms three groups based on the relatedness of their DNA to that of the ‘pathogenic’ Neisseria which have at least 80% of their nucleotide sequences similar; the ‘non-pathogenic’ Neisseria which share only 8 to 15 %; and which shows no relatedness.
