Popis: The name ‘Mycobacterium angelicum’ dates back to 2003 when it was suggested for a slowly growing mycobacterium isolated from freshwater angelfish. This name is revived here and the novel species is proposed on the basis of the polyphasic characterization of four strains including the original one. The four strains presented 100 % 16S rRNA gene sequence similarity withMycobacterium szulgaibut clearly differed fromM. szulgaifor the milky white aspect of the colonies. The sequence similarity with the type strain ofM. szulgairanged, in eight additionally investigated genetic targets, from 78.9 to 94.3 %, an evident contrast with the close relatedness that emerged at the level of 16S rRNA gene. The average nucleotide identity between the genomes ofM. szulgaiDSM 44166Tand strain 126/5/03T(type strain of the novel species) was 92.92 %, and supported the status of independent species. The confirmation of the nameMycobacterium angelicumsp. nov. is proposed, with strain 126/5/03T( = CIP 109313T = DSM 45057T) as the type strain.
