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