mycobacterium montefiorense mycobacterium montefiorense mycobacterium montefiorense is a species of bacteria which cause granulomatous skin disease of moray eels. sequence analysis, of the 16s rrna gene reveals m. montefiorense is most closely related to mycobacterium triplex, an opportunistic pathogen of humans. mycobacterium montefiorense scientific classification domain: bacteria phylum: actinomycetota class: actinomycetia order: mycobacteriales family: mycobacteriaceae genus: mycobacterium species: m. montefiorense binomial name mycobacterium montefiorenselevi et al. 2003, atcc baa-256 m. montefiorense was named after the montefiore medical center, bronx, n.y., the medical institution where it was isolated. description m. montefiorense are acid-fast rods which grow on middlebrook 7h10 media at 25 °c to form small, transparent, slow-growing colonies. m. montefiorense do not grow at temperatures above 30 °c. the strain atcc baa-256 = ccug 51898 = dsm 44602. pathogenesis m. montefiorense has been demonstrated to cause granulomatous skin disease of moray eels.
