Yes, Actinomyces is true bacteria. Actinomyces is a genus of anaerobic, Gram-positive, rod-shaped bacteria in the family Actinomycetaceae. They are found in soil, water, and animal tissue, and are commonly found in the human body, particularly in the oral cavity and the gastro-intestinal tract.
Actinomyces are thought to play an important role in the maintenance of healthy oral and gastro-intestinal microbial flora, and they are known to be involved in the pathogenesis of several diseases, including dental caries, periodontal disease, and tuberculosis.
Though Actinomyces are bacteria, they are distinct from other bacteria in their morphology and physiology. Actinomyces are highly branched, with filaments that spread from the center of the cell, giving them a distinctive star-like appearance. Unlike other bacteria, they are also capable of forming spores.
In summary, Actinomyces are true bacteria, and they are found in soil, water, and animal tissue, and in the human body. They have a distinct morphology, and have the ability to form spores. They are thought to play an important role in the maintenance of healthy oral and gastro-intestinal microbial flora, and they are known to be involved in the pathogenesis of several diseases.
