Result (p-values) from the test of individual links with ParaFit for the species with an insignificant result (α = 0.05) in the first approach. The comparison was done between an unconstrained ML tree and the first, genus-based constraint (second column) or the second constraint, based on a revised classification of the group (third column). Note that with a single exception the phylogenetic conflict was resolved by assigning S. coccoides to Sphaerochaeta [4] and three other Spirochaeta species to Treponema [46].
