Actinomyces species may form endospores, and while individual bacteria are rod-shaped, Actinomyces colonies form fungus-like branched networks of hyphae. [3] The aspect of these colonies initially led to the incorrect assumption that the organism was a fungus and to the name Actinomyces , "ray fungus" (from Greek actis , ray or beam, and mykes ...
While this role is also played by fungi, Actinomycetota are much smaller and likely do not occupy the same ecological niche. In this role the colonies often grow extensive mycelia , as fungi do, and the name of an important order of the phylum, Actinomycetales (the actinomycetes), reflects that they were long believed to be fungi.
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 ...
Some actinomycetes can form rod- or coccoid-shaped forms, while others can form spores on aerial hyphae. Actinomycetales bacteria can be infected by bacteriophages , which are called actinophages. Actinomycetales can range from harmless bacteria to pathogens with resistance to antibiotics.

This bacterium is a member of the genus Actinomyces and its taxonomic classification is as follows: Bacteria, Actinomycetota, Actinomycetes, Actinomycetales, Actinomycetaceae, Actinomyces, Actinomyces massiliensis. [4] To date, there are over 30 species of Actinomyces documented in the literature. [5]
These bacteria could fix nitrogen, in time multiplied, and as a result released oxygen into the atmosphere. [2] [3] This led to more advanced microorganisms, [4] [5] which are important because they affect soil structure and fertility. Soil microorganisms can be classified as bacteria, actinomycetes, fungi, algae and protozoa. Each of these ...
Actinomycetes are Gram-positive bacteria that are some of the most common bacteria in soil, freshwater and marine environments. Actinomycetes are active in decomposition of organic matter and give rise to the rich "earthy" smell of freshly tilled soils.
