sp. nov. and sp. nov., two species isolated from human skin infection Open Access

Abstract

Two slow-growing nontuberculous mycobacterial strains were isolated from clinical skin lesions in Jiangsu, PR China, and identified as novel species within the genus . The bacterial colonies exhibited scotochromogenic pigmentation and rod-shaped morphology, and they were classified as acid-fast bacilli. Phylogenetic analysis indicated that the two strains were closely related to . The two strains, X7091 and Z3061, exhibited average nucleotide identity and DNA–DNA hybridization values below the threshold for species delineation when compared with other type strains of complex. Therefore, two novel species are proposed: sp. nov., with the type strain being X7091 (=CGMCC 1.90336=JCM 37414), and sp. nov., with the type strain being Z3061 (=CGMCC 1.90337=JCM 37415).
