II (S3, S6, S10, S13, S21, S25)	6 (23%)	Mycobacterium fortuitum
III (S12, S18, S23)	3 (12%)	Mycobacterium goodii
IV (S2, S24)	2 (1%)	Mycobacterium arupense
V (S11, S17)	2 (1%)	Mycobacterium peregrinum or M.septicum
VI (S20)	1 (0.04%)	Mycobacterium elephantis
VII (S7, S14, S15, S19, S22)	5 (19%)	Non-Mycobacterium species (Gordonia terrae)
