Morphological and physiological properties of these isolates were distinct from those of previously described Streptomyces species. Strain S63T has yellow-white, smooth, cylindrical spores that are borne in monoverticillus flexuous spore-chains. Strain S77T has purple-red, spiny spores that are borne in simple rectus flexuous spore-chains. Strain S78T has white, smooth, cylindrical spores that are borne in simple rectus flexuous spore-chains. These three isolates differed from known pathogenic strains by analysis of 16S rRNA gene sequences in a previous study. Furthermore, genetic uniqueness of our isolates was confirmed by sequencing of the 16S–23S internal transcribed spacer (ITS) region, which indicated that isolates S63T and S78T belong to the genus Streptomyces and have low homology to other Streptomyces species (less than 71·2 and 75·7 %, respectively). The 16S–23S ITS region of strain S77T was not amplified by these primer sets. DNA–DNA hybridization results for all three isolates show distant relationships to previously described Streptomyces species; therefore, on the basis of polyphasic evidence, the names Streptomyces luridiscabiei sp. nov. for strain S63T (=LMG 21390T=KACC 20252T), Streptomyces puniciscabiei sp. nov. for strain S77T (=LMG 21391T=KACC 20253T) and Streptomyces niveiscabiei sp. nov. for strain S78T (=LMG 21392T=KACC 20254T) are proposed. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.02629-0
