Ozoroa insignis reticulata (Baker f.) R. Fern. & A. Fern. Root Extract Inhibits the Production of Extracellular Proteases by Staphylococcus aureus

Figure 3

The effects of the O. reticulata ethyl acetate extract on the production of extracellular proteases by S. aureus. A distinct halo is produced for the positive control (a), less distinct haloes are produced on plates containing 100 µg/mL (b) and 200 µg/mL (c) of the ethyl acetate extract while no growth or haloes are obtained for the negative control (d) after 24 h of incubation.
