Actinomyces is a genus of the Actinomycetia class of bacteria. They all are Gram-positive and facultatively anaerobic , growing best under anaerobic conditions. [ 2 ] Actinomyces species may form endospores , and while individual bacteria are rod-shaped , Actinomyces colonies form fungus -like branched networks of hyphae . [ 3 ]
Actinomycosis Grocott's stain Actinomycosis Gram stain. Actinomycosis is primarily caused by any of several members of the bacterial genus Actinomyces. These bacteria are generally anaerobes. [7] In animals, they normally live in the small spaces between the teeth and gums, causing infection only when they can multiply freely in anoxic ...
Scanning electron micrograph of Actinomyces israelii. Scientific classification; Domain: Bacteria: Phylum: Actinomycetota: Class: Actinomycetia (Stackebrandt et al. 1997) Salam et al. 2020 [1] Type genus; Actinomyces
The two micro-organisms exhibit dynamic interactions, since TM7x is obligately [27] [28] and exclusively physically associated with its host Actinomyces odontolyticus strain XH001, with various phases that include co-existence, induction of lysis in addition to exospore formation. This is an example of parasitic ectosymbiosis.
Cutaneous actinomycosis is a chronic disease that affects the deep subcutaneous tissue of the skin. Caused by an anaerobic, Gram-positive, filamentous type of bacteria in the genus Actinomyces, [1]: 270 invasion of the soft tissue leads to the formation of abnormal channels leading to the skin surface (external sinus tracts) that discharge pale yellow sulfur granules.

Actinomycetales can be found mostly in soil and decaying organic matter, as well as in living organisms such as humans and animals. They form symbiotic nitrogen fixing associations with over 200 species of plants, and can also serve as growth promoting or biocontrol agents, or cause disease in some species of plants.
The Actinomycetota (or Actinobacteria) are a diverse phylum of Gram-positive bacteria with high GC content. [4] They can be terrestrial or aquatic. [5] They are of great importance to land flora because of their contributions to soil systems. In soil they help to decompose the organic matter of dead organisms so the molecules can be taken up ...
