Skin microbiota is the main reservoir of Roseomonas mucosa, an emerging opportunistic pathogen so far assumed to be environmental S. Romano-Bertrand, A. Bourdier, F. Aujoulat, A.-L. Michon, A. Masnou, S. Parer, H. Marchandin, E. Jumas-Bilak Clinical Microbiology and Infection Volume 22, Issue 8, Pages 737.e1-737.e7 (August 2016) DOI: 10.1016/j.cmi.2016.05.024 Copyright © 2016 European Society of Clinical Microbiology and Infectious Diseases Terms and Conditions

Fig. 1 Maximum likelihood tree based on 1258-bp 16S rRNA gene sequences showing phylogenetic relationships among natural isolates and 22 species type strains in the genus Roseomonas (bold face). Accession number (in brackets) and origin of strains are given at the end of tree branches. Bootstrap values are given at branch nodes. The very recently described species are not included in the tree but affiliated to the defined clades: Roseomonas oryzicola (clade IV), Roseomonas eburnea (clade IV), Roseomonas elaeocarpi (clade VI) and Roseomonas arctica (clade V). The sequences of the species Roseomonas oryzae and, Roseomonas wooponensis are not yet available.

Fig. 3 Maximum likelihood tree based on 16S rRNA gene sequences (1321 bp) showing phylogenetic relationships among 70 human-originating sequences, natural isolates and type strains of Roseomonas species. The 70 human-originating sequences were selected as follows: only one sequence per group of sequences displaying more than 99.5% identity. *Bootstrap values <70%.

Fig. 4 Distribution of metagenomic sequences affiliated to the genus Roseomonas according to the site of sampling. (a) Number of Roseomonas sequences detected in the “American gut project” according to species and to human body sites. Nostril (two sequences of Roseomonas sp.) and hair (six sequences of R. mucosa) are not represented in the figure. Other body sites are negative for Roseomonas sequences. (b) Average number of Roseomonas sequences by project deposited in the EBI Metagenomics database according to species and to ecosystem. For human body sites, there were no Roseomonas sequence in mouth, respiratory tract and vagina (not shown in the figure).
