Effect of Clinoptilolite and Sepiolite Nanoclays on Human and Parasitic Highly Phagocytic Cells

Figure 2

Viability of E. histolytica after the treatment with nanoclays. Amoebic cultures were treated with clinoptilolite (a) or sepiolite (b) NC for the period of time indicated and the viability measured by the Trypan blue method. Bottom pictures show CFDA/PI stained trophozoites from the treated cultures at the concentrations and time indicated. Controls are amoebas from a culture without treatment. The shifting of green to yellowish fluorescent indicates decrease of viability. Red nuclei come from dead cells.
