Pulmonary disease caused by Mycobacterium meguroense, a newly identified slow-growing mycobacterium, after umbilical cord blood transplantation: A case report from Japan and a mini-review of the literature

We report pulmonary disease associated with an unclassified nontuberculous mycobacterium after umbilical cord blood transplantation. Genomic analyses assigned our isolates to the same species as feline strain MFM001, a species for which we propose the name Mycobacterium meguroense . Multidrug therapy was followed by clinical improvement and mycobacterial culture conversion.
