Mycobacterium xenopi

Mycobacterium xenopi is a slow-growing scotochromogenic species of Mycobacterium. It was first reported by Schwabacher in 1959, having been isolated in lesions found on a Xenopus laevis, but the possibility of human infection was not confirmed until 1965. It has low pathogenicity in humans, and where infections have been found they are closely associated with immunocompromised individuals.
