Streptomyces strain NRRL B-2795T (DSM 112329T=NRRL B-2795T) is described as the type strain of Streptomyces griseiscabiei sp. nov. using whole-genome average nucleotide identity and multilocus sequence analyses in addition to phenotypic characterization of carbon source utilization, spore chain morphology, melanin production, salt tolerance, pH tolerance, plant pathogenicity and antibiotic resistance. This strain was previously classified as Streptomyces scabiei but suggested as a potential novel species. A second Streptomyces strain, NRRL B-16521, previously named Streptomyces scabiei, and also previously suggested as a potential novel species, is assigned to Streptomyces acidiscabies based on whole-genome average nucleotide identity. Morphological and biochemical characterizations also support this designation for NRRL B-16521. Both Streptomyces sp. strain NRRL B-2795T and NRRL B-16521 cause common scab on multiple cultivars of potato.
