a Quercetin disrupts the mitochondria membrane potential (MMP) in extracellular T. gondii tachyzoites. White arrows indicate parasites. The panel with red represents the uncompromised MMP in parasites and the panel with green indicates the compromised MMP in parasites treated with Que (0.62 and 16.67 µM) and a standard compound (CCCP) at 50 µM. The green indicates compromised MMP. Scale bar: 200 µm. b Que disrupts the MMP in intracellular T. gondii tachyzoites. Small white arrows indicate parasites, and short large arrowheads indicate host cells. The red spikes indicate intact mitochondria in tachyzoites treated with Que (0.62 and 16.67 µM) and a standard compound CCCP at 50 µM. The green indicates the compromised MMP. Scale bar: 200 µm. CCCP, Carbonyl cyanide m-chlorophenyl hydrazone; Que, quercetin
