Parasitized erythrocytes stained with hydroethidine were detected in the FL-2 channel, and are represented in the bottom right quadrant. (a) Normal uninfected erythrocytes stained with hydroethidine (negative control). (b)
T. equi-infected erythrocytes incubated without imidocarb dipropionate (IMD; positive control). (c)
T. equi-infected erythrocytes incubated with 2.76 μM IMD.
