Schwabacher 1959, ATCC 19250

Mycobacterium xenopi is a slow-growing scotochromogenic species of Mycobacterium. It was first reported by Schwabacher[1] 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,[2] and where infections have been found they are closely associated with immunocompromised individuals.

Type strain: strain ATCC 19250 = CCUG 28011 = CCUG 31306 = CIP 104035 = DSM 43995 = NCTC 10042.
