Data Values are presented as mean + SD (n = 3)
--: no zone of inhibition, LSD all pair wise comparison Alpha 0.05 (a*, b*, etc.) in which the means are not significantly different from one a another
Positive control = Cef (Cefixime) and Rox (Roxithromycin), Negative control = DMSO (no zone of inhibition)
MIC: 1 = 50 μg/ml, 2 = 50 μg/ml, 3 = 75 μg/ml,4 = 75 μg/ml,5 = 75 μg/ml,6 = 75 μg/ml,7 = 75 μg/ml,8 = 75 μg/ml,9 = 75 μg/ml
