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 ...
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 ...
Actinomyces and its associated species have, for a long time, been implicated in human infections, particularly those of the mouth, pharynx, distal esophagus, and genitourinary tract. [9] Within the last 10 years, A. massiliensis has been detected in blood, and most Actinomyces bacteremias stem from oral sources. [ 9 ]
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.
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 ...
Actinomyces israelii is a species of Gram-positive, rod-shaped bacteria within the genus Actinomyces. Known to live commensally on and within humans, A. israelii is an opportunistic pathogen and a cause of actinomycosis .
'Bacterium actinomycetem comitans' was first described by Klinger (1912) as coccobacillary bacteria isolated with Actinomyces from actinomycotic lesions in humans. It was reclassified as Actinobacillus actinomycetemcomitans by Topley & Wilson (1929) and as Haemophilus actinomycetemcomitans by Potts et al. (1985). The species has attracted ...
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.
