The Actinomycetaceae (often called actinomycetes or mycilial 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.


The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature [1] and National Center for Biotechnology Information (NCBI)[2] and the phylogeny is based on 16S rRNA-based LTP release 106 by 'The All-Species Living Tree' Project[3]
