Phylogeny of the family Anaplasmataceae constructed using maximum-likelihood (ML) estimations based on (A) 16S rRNA sequences with a total of 1157 unambiguously aligned bp (best-fit approximation for the evolutionary model: K2+G+I), and (B) on short-length 16S rRNA sequences of Ca. Allocryptoplasma with a total of 202 unambiguously aligned bp (best-fit approximation for the evolutionary model: K2+G+I). All genera of the family Anaplasmataceae, including representative species, are indicated. *, Ca. Allocryptoplasma sequences obtained in this study (GenBank accession numbers OQ724839–OQ724862). GenBank accession numbers of other sequences used in analyses are shown on the phylogenetic trees. Numbers at nodes indicate percentage support of 1000 bootstrap replicates. Only bootstrap values >70% are shown. The scale bar is in units of substitution/site.
