Chronic Toxoplasma infection of human skin cells

Toxoplasma is a parasite that moves in for good: once the infection turns chronic, it walls itself into cysts that no drug can reach. These ones are sitting inside human skin cells.

Look for the red net around each cyst — that's the host cell crowding its own power plants (mitochondria) up against the intruder, a siege of sorts.
