Phylogenetic tree highlighting the position of S. termitidis NCTC 11300^T relative to the other type strains within the family ‘Leptotrichiaceae’. The tree was inferred from 1,422 aligned characters [9,10] of the 16S rRNA gene sequence under the maximum likelihood criterion [11] and rooted in accordance with the current taxonomy. The branches are scaled in terms of the expected number of substitutions per site. Numbers above branches are support values from 1,000 bootstrap replicates if larger than 60%. Lineages with type strain genome sequencing projects registered in GOLD [12] are shown in blue, published genomes in bold, e.g. the recently published GEBA genomes from Leptotrichia buccalis [13], and Streptobacillus moniliformis [14].
