The Antibacterial Assay of Tectorigenin with Detergents or ATPase Inhibitors against Methicillin-Resistant Staphylococcus aureus
Figure 6
Transmission electron microscopy (TEM) images of methicillin-resistant Staphylococcus aureus (MRSA) (ATCC 33591) after 24 h of tectorigenin (TTR) treatment. (a) MRSA in the untreated control appeared to have intact membrane; (b) MRSA treatment with 1/2 MIC TTR (62.5 μg/mL) hampered membrane integrity and caused membrane damage; (c) MRSA treatment with MIC TTR (125 μg/mL) showed cytoplasmic membrane disruption and separated cell.
