Abstract

Roseomonas spp. are increasingly involved in human infectious diseases. The environmental source for infection is generally admitted in published cases owing to the origin of most Roseomonas species and to their affiliation to the family Acetobacteraceae in Rhodospirillales, which mainly groups environmental bacteria. For a better delineation of Roseomonas habitat and infectious reservoir, we related phenotype, phylotype (16S rRNA gene), genomotype (Pulsed-Field Gel Electrophoresis) and origin of 33 strains isolated from human, hospital environment and natural environment. Genetic databases were also surveyed. The population structure of the genus showed clades associated to human whereas others grouped environmental strains only. Roseomonas mucosa is the main human-associated speciesandthe study supported that opportunistic infections due to this species are related to the patient skin microbiota rather than to the environment. Contrarily, some strains belonging to other species isolated from cystic fibrosis patients were related to environmental clades suggesting an exogenous source for patient colonization. Accurate knowledge about the reservoirs of opportunistic pathogensfor longconsidered to be of environmental origin is still needed andwould be helpful to improve infection control and epidemiological survey of emerging human pathogens.

This web-only appendix provides details on origin (Table S1), biotype (Table S2) and antibiotype (Table S3) of the Roseomonas isolates and strains analyzed in this study. It also provides Pulsed-Field Gel Electrophoresis (PFGE) patterns (SpeI digestion) showing intra-genus (Figure S1) and intra-species (Figure S2) diversity of Roseomonas. UPGMA clusterisations performed by using biotyping and PFGE data are also displayed (Figures S1, S2 and S3).
