Summary The life cycle of virulent toxoplasma has been studied in slide cell cultures by means of continuous observation using phase microscopy. The active penetration of the host cell membrane by the parasite could be demonstrated by cinematography. Penetration occurs within 15 to 30 seconds. The special mode of toxoplasma division called “endodyogeny” was examined, as well as the development of the rosette‐like terminal colonies of parasites. Virulent toxoplasma destroy their host cells. The free toxoplasma show active mobility and are able to invade new cells.
