Monensin affects mitochondrial morphology.

<p>Phase-contrast and deconvolved immunofluorescence micrographs showing effect of monensin (0.75 ng/ml, 24 hours) on several <i>T. gondii</i> intracellular structures. (A) Phase contrast and DAPI staining of DNA showing parasite nuclei (PN) and apicoplast DNA (ADNA). HCN = host cell nuclei. (B) Phase contrast and immunofluorescence staining showing Atrx1 protein in the apicoplasts. (C) Phase contrast and immunofluorescence staining of TgNHE3 showing parasite plant-like vacuoles. (D) Phase contrast and immunofluorescence showing parasite mitochondria. Scale bars = 10 µm.
