Common scab strains from the northeastern United States, Atlantic Canada, and Hungary were differentiated by a phenotypic analysis of 42 criteria from six atypical pathogen strains, three saprophytic streptomycetes isolated from scab lesions, and reference strains of Streptomyces griseus and Streptomyces tendae. The 12 S. scabies strains formed a homogeneous group characterized by smooth grey spores borne in spiral chains, melanin production, and usage of all International Streptomyces Project sugars. Most S. scabies isolates did not degrade xanthine and were susceptible to 25 µg of oleandomycin per ml, 10 IU of penicillin G per ml, 20 µg of streptomycin per ml, 10 µg of thallous acetate per ml, and 0.5 µg of crystal violet per ml. The type strain of S. scabies is strain RL-34 (= ATCC 49173)., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/00207713-39-4-387
