Answer

C minutissimum, a member of the normal skin flora, is the causative agent of erythrasma. The bacterium is a lipophilic, gram-positive, non–spore-forming, aerobic, and catalase-positive diphtheroid. C minutissimum ferments glucose, dextrose, sucrose, maltose, and mannitol.

Whole-genome sequencing of C minutissimum has been reported to better understand the multiantibiotic resistance that has been observed and its virulence factors specifically in immunocompromised hosts. The will make it possible to identify the genes contributing to antibiotic resistance and to better design treatment options in these special cases. [3]
