Maximum likelihood tree showing the phylogenetic position of Candidatus Mycoplasma haematodidelphidis isolate Illinois within the Hemoplasma cluster of Mycoplasmataceae based on 16S rRNA gene sequences. The sequence of Mycoplasma hyopneumoniae J^T was used as out-group (Hyopneumoniae cluster). Numbers at nodes represent bootstrap confidence values (1000 replications). Only values > 80% are shown. Bar, number of substitutions per nucleotide position. Credits: Joachim Spergser (Vetmeduni Vienna)
