tuberculosis (33 MDR, 34 non-MDR) isolates showed MIC50
and 90 values of 0.5 [micro]g/mL in a study by Ermertcan et al.

Table I.- Values of MIC50
MIC90 MIC range and mode for clinical strains.
The lowest concentration that inhibited 50% of visual growth was recorded and interpreted as the MIC50
. The MIC testing was performed according to the recommendations of the Clinical and Laboratory Standards Institute (CLSI).
The extracts demonstrated anti-Th pylori activity with zone of inhibition range of 0-38 mm and MIC50
range of 0.06-5.0 mg/mL, respectively.
and MIC90 of these isolates were found to be respectively 0.094[micro]g/ml and 0.125[micro]g/ml.

Bacterial growth inhibition is expressed in terms of MIC50
(ug/mL) which is defined as the minimum amount of substance to inhibit 50% bacterial growth.
To derive species sensitivity distributions, we used pooled MIC50
and NOEC values only from genera for which there was evidence to suggest that--under certain conditions--the genera could grow in an environmental compartment (e.g., soil, sewage, fresh water) (for details regarding the selection of genera, see Supplemental Material, Section 2 and Table S2).
As reported in Table 1, for all the twenty MRSA clinical isolates and the ATCC43300, MIC50
and MIC90 were calculated, as well as [MBC.sub.50] and [MBC.sub.90].
