In Vitro Antimicrobial Susceptibility of Mycobacterium massiliense Recovered from Wound Samples of Patients Submitted to Arthroscopic and Laparoscopic Surgeries

Table 1

Antimicrobial susceptibility of 18 Mycobacterium massiliense strains recovered from wound infections after arthroscopic and laparoscopic surgeries during an outbreak in Goiânia, Goiás, Brazil.

Antimicrobial	MIC50	MIC90	%
Amikacin	<2	4	100 (S)
Cefoxitin	32	64	100 (I)
Ciprofloxacin	>16	>16	100 (R)
Clarithromycin	<1	<1	100 (S)
Doxycycline	>32	>32	100 (R)
Sulfamethoxazole	>128	>128	100 (R)
Tobramycin	>32	>32	100 (R)

All results were determined by broth microdilution method; I: Intermediate; R: resistant; S: susceptible; CIM₅₀: the MIC capable of preventing the growth of 50% of the isolates; MIC₉₀: the MIC capable of preventing the growth of 90% of the isolates.
