Acute-stage Toxoplasma parasites living in human skin cells

Acute-stage Toxoplasma parasites, overgrown after three days of infection of human skin cells.

The DNA of every cell is depth-coded, so colour tells you how deep in the sample a nucleus sits — the higher up, the warmer.

The larger nuclei belong to the skin cells, the small tightly packed ones to the parasites.
