Comparison of in vitro drug susceptibility profiles between M. intracellulare and M. avium isolates

Antimicrobial agents	No. of resistant isolates (%)		P value
	M. avium (n = 95)	M. intracellulare (n = 159)
Clarithromycin	4 (4.2)	6 (3.8)	1.000
Moxifloxacin	5 (5.3)	8 (5.0)	1.000
Linezolid	11 (11.6)	13 (8.2)	0.370

The breakpoints to establish susceptibility and resistance for clarithromycin, moxifloxacin and linezolid were followed as recommendation from Clinical and Laboratory Standards Institute (CLSI-M24-A2)
