Actinomycosis is a rare infectious bacterial disease caused by the gram-positive Actinomyces species. [1] The name refers to ray-like appearance of the organisms in the granules. About 70% of infections are due to either Actinomyces israelii or A. gerencseriae. [1] Infection can also be caused by Streptomyces somaliensis and Propionibacterium ...
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 ...
It is a chronic inflammatory disease caused by the blockage of pilosebaceous units causing inflammatory lesions, non-inflammatory lesions or a mixture of both on the face, neck and/or chest. [10] [11] Acne vulgaris cannot be defined as an infectious disease since the bacteria is found on a vast majority of individuals without causing lesions. [10]

Actinomycetoma is a chronic bacterial subcutaneous infection caused by Actinomyces that affect the skin and connective tissue. [1] It is, therefore, a form of actinomycosis . [ 2 ] Mycetoma is a broad term which includes actinomycetoma and eumycetoma under it.
Infection is caused as a result of localized skin trauma, such as stepping on a needle or wood splinter, or through a pre-existing wound. [ 10 ] The first visible symptom of mycetoma is a typically painless swelling beneath the skin; over several years, this will grow to a nodule (lump). [ 9 ]
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.
Actinomycetota, especially Streptomyces spp., are recognized as the producers of many bioactive metabolites that are useful to humans in medicine, such as antibacterials, [18] antifungals, [19] antivirals, antithrombotics, immunomodifiers, antitumor drugs, and enzyme inhibitors; and in agriculture, including insecticides, herbicides, fungicides ...
