One hundred thirty-six isolates, 88 human and 48 environmental, that met the requirements to belong to the genus were identified using a polyphasic taxonomic approach known as 16S rRNA plus phenotypic traits. Thirty-seven species were identified; some had not been previously reported from clinical samples. The main species were (13 isolates), (11), (9) and (8). (11/13) and (8/11) were mainly environmental isolates, while (9/9) and (6/8) were mainly human isolates. Despite the difficulties in assigning to human isolates a role as a pathogen or contaminant, here 25% of the isolates were involved in true infections, especially in those cases that affected abscesses, wound exudates, ocular infections and diverse fluids. In addition, 15 isolates were identified as 11 to a new species, all of them from human specimens except one that was obtained from laboratory air The antimicrobial susceptibility testing showed 95.6% of isolates were resistant to ampicillin, 44% were resistant to cotrimoxazole, 20 to 30% were resistant to cefotaxime and vancomycin and 13% were resistant to rifampicin and erythromycin.

The genome of a spore-forming bacterium isolated from the spacecraft assembly facility of the Phoenix mission, was generated via hybrid assembly by merging short and long reads. Examining this genome may shed light on strategies to minimize the risk of contaminating extraterrestrial environments with Earth-based microorganisms.
