Cell Line:E. coli (16 strains), P. aeruginosa (13 strains), and S. aureus (17 strains)
-
Concentration:0-64 µg/mL
-
Incubation Time:18-24 h
-
Result:Inhibited E. coli (16 strains), P. aeruginosa, and S. aureus with MIC ranges of <0.004-0.5 (MIC 90%=0.06, =0.06), 0.5-2 (MIC 90%=1, MIC 50%=1) and 0.06-0.25 µg/mL (MIC 90%=0.125, MIC 50%=0.125). MIC 90% and 50% means MIC for 90% and 50% of the isolates (unit: µg/mL).
