Two slow-growing nontuberculous mycobacterial strains were isolated from clinical skin lesions in Jiangsu, PR China, and identified as novel species within the genus Mycobacterium . 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 Mycobacterium gordonae . The two strains, X7091 T and Z3061 T , exhibited average nucleotide identity and in silico DNA–DNA hybridization values below the threshold for species delineation when compared with other type strains of M. gordonae complex. Therefore, two novel Mycobacterium species are proposed: Mycobacterium camsae sp. nov., with the type strain being X7091 T (=CGMCC 1.90336 T =JCM 37414 T ), and Mycobacterium pumcae sp. nov., with the type strain being Z3061 T (=CGMCC 1.90337 T =JCM 37415 T ).
