When counting the food vacuoles, not all of the tetrahymena pyriformis were dead.
2.
The chemoattractant activity of IL-8 in similar concentrations to vertebrates was proven in Tetrahymena pyriformis, which suggests a phylogenetically well-conserved structure and function for this chemokine.

Similarly, Tetrahymena Pyriformis is a protozoan, a unicellular eukaryotic organism, which can be identified by its pear-shaped body and its strong mobility and activity . vT . Pyriformis has a short life cycle which is ideal for experiments done using this organism.
