Medical Definition of STREPTOMYCES

capitalized : the type genus of the family Streptomycetaceae comprising mostly soil actinomycetes including some that form antibiotics as by-products of their metabolism
plural streptomyces : any bacterium of the genus Streptomyces


noun    (Concise Encyclopedia)

Any of the threadlike bacteria that make up the genus Streptomyces, occurring in soil and water. These gram-positive (see gram stain), oxygen-requiring bacteria form a branching net called a mycelium that bears chains of spores at maturity. Many species are important in the decomposition of organic matter in soil, contributing in part to the earthy odour of soil and decaying leaves and to the fertility of soil. Certain species produce antibiotics such as tetracycline and streptomycin. See also actinomycete.
