Effect of Virkon treatment on T. cruzi epimastigote viability in rat blood.

T. cruzi strain Silvio X10/7 subclone A1 infected rat blood, was treated for 1 h with a 10-fold (v/v) excess of 1% Virkon. Samples were pelleted and resuspended in the same volume of culture medium before 10-fold dilution into culture medium. Viable parasites were detected by microscopic examination for motile epimastigotes and scored qualitatively. Parasite positive samples are highlighted as a heat map.
