title: Aramycin, a streptothricin-like antibiotic, produced by a local strain of Streptomyces MYS-20A.
abstract: One strain of actinomycetes, designated as MYS-20 A, was isolated from the Egyptian soil. The organism produces a substance that appears to be different from previously described antibiotics. The substance was named "Aramycin". A description of the strain of actinomyces MYS 20 A is given as well as conditions of growth for maximum production of the antibiotic substance. The bacterial and fungal spectra of aramycin are given. The substance appears to exhibit a very significant cytotoxic effect. The antibiotic was toxic to mice, the lethal dose being, however, about 15 times higher than the curative dose.
