Streptomyces is the largest genus of Actinomycetota, and the type genus of the family Streptomycetaceae. [3] Over 700 species of Streptomyces bacteria have been described. [ 4 ] [ 5 ] [ 6 ] As with the other Actinomycetota, streptomycetes are gram-positive , and have very large genomes with high GC content .
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 propionicus. The condition is likely to be a polymicrobial anaerobic infection. [2]
The environment present in the human mouth allows the growth of characteristic microorganisms found there. It provides a source of water and nutrients, as well as a moderate temperature. [ 2 ] Resident microbes of the mouth adhere to the teeth and gums to resist mechanical flushing from the mouth to stomach where acid-sensitive microbes are ...
Streptomyces antibioticus (previously known as Actinomyces antibioticus) is a gram-positive bacterium discovered in 1941 by Nobel-prize-winner Selman Waksman and H. Boyd Woodruff. [ 1 ] [ 2 ] Its name is derived from the Greek "strepto-" meaning "twisted", alluding to this genus ' chain-like spore production, [ 3 ] and " antibioticus ...
Streptomyces isolates have yielded the majority of human, animal, and agricultural antibiotics, as well as a number of fundamental chemotherapy medicines. Streptomyces is the largest antibiotic -producing genus of Actinomycetota , producing chemotherapy, antibacterial, antifungal , antiparasitic drugs, and immunosuppressants . [ 1 ]
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]
Mouth infections, also known as oral infections, are a group of infections that occur around the oral cavity. They include dental infection , dental abscess , and Ludwig's angina . Mouth infections typically originate from dental caries at the root of molars and premolars that spread to adjacent structures.
Streptomycin is an antibiotic medication used to treat a number of bacterial infections, [3] including tuberculosis, Mycobacterium avium complex, endocarditis, brucellosis, Burkholderia infection, plague, tularemia, and rat bite fever. [3] For active tuberculosis it is often given together with isoniazid, rifampicin, and pyrazinamide. [4]
