The Actinomycetaceae (often called actinomycetes or mycelial bacteria) are a family of bacteria in the order Actinomycetales that contains the medically important genus Actinomyces. These organisms are closely related to the mycobacteria, but were originally classified as fungi because they were thought to be transitional forms between bacteria and fungi.

Genera

The family Actinomycetaceae comprises the following genera:[2]

Phylogeny

The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN).[2] The phylogeny is based on whole-genome analysis.[3][lower-alpha 1]
