Streptomyces scabies Streptomyces scabies or Streptomyces scabiei is a streptomycete bacterium species found in soils around the world. Unlike most of the 500 or so "Streptomyces" species it is a plant pathogen causing corky lesions to form on tuber and root crops as well as decreasing the growth of seedlings. Along with other closely related species it causes the potato disease common scab, which is an economically important disease in many potato growing areas. It was first described in 1892, being classified as a fungus, before being renamed in 1914 and again in 1948. Several other species of "Streptomyces" cause similar diseases to "S. scabies" but other, more closely related species, do not.
