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 ]
The antibiotic described was found to show antimicrobial activity against gram-negative bacteria, gram-positive bacteria, and pathogenic fungi. [9] In addition to producing antibiotics, one strain of S. antibioticus has been discovered to induce a different species of Streptomyces to produce antibiotics. [11]
Bactericidals kill bacteria directly, whereas bacteriostatics prevent them from dividing. However, these classifications are based on laboratory behavior. The development of antibiotics has had a profound effect on the health of people for many years. Also, both people and animals have used antibiotics to treat infections and diseases.
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.
Plague (Yersinia pestis): Has historically been used as the first-line treatment. However streptomycin is approved for this purpose only by the US Food and Drug Administration. [medical citation needed] In veterinary medicine, streptomycin is the first-line antibiotic for use against gram negative bacteria in large animals (horses, cattle ...
They are also the source of many antibiotics. [9] [10] The Actinomycetota genus Bifidobacterium is the most common bacteria in the microbiome of human infants. [11] Although adults have fewer bifidobacteria, intestinal bifidobacteria help maintain the mucosal barrier and reduce lipopolysaccharide in the intestine. [12]

The antibiotic treatment may select for bacterial strains with physiologically or genetically enhanced capacity to survive high doses of antibiotics. Under certain conditions, it may result in preferential growth of resistant bacteria, while growth of susceptible bacteria is inhibited by the drug. [ 84 ]
