Since its discovery, Propionibacterium acnes has undergone various name changes, and has been known since 2016, as Cutibacterium acnes. Herein we set out the history and rational of these taxonomic changes together with a description of a new genus, Cutibacterium, which includes five species within the cutaneous ecosystem. Modern microbiological techniques allow finer distinction between species and subspecies while also enabling the identification of separate subtypes within the population of Cutibacterium acnes. Phylogeny and molecular typing techniques thus provide a better understanding of the subtypes involved in certain inflammatory skin diseases, including acne, folliculitis and progressive macular hypomelanosis.
