Bayesian consensus phylogenetic tree of 1,359 aligned characters from the 16S rRNA gene sequence of strain 2002 and members of the family Neisseriaceae after 4,000,000 generations with a sample frequency of 1,000. Results from Bayesian posterior probability are indicated at the nodes as follows: filled circle 1.00, empty circle >0.90, filled square, 0.80–0.90; empty square <0.80. Methylophilus methylotrophus, a member of the family Methylophilaceae within the Betaproteobacteria, served as the outgroup. The same topology was obtained with maximum-likelihood analysis
