Abstract Amöbe. Schlüpfen aus der Zyste, Fortbewegung durch Pseudopodien, Umwandlung zur begeißelten Schwimmform, Umwandlung zur Kriechform. Nahrungsaufnahme durch Phagozytose und Lyse der Futterbakterien. Verschiedene Phasen der Kern- und Zellteilung. Enzystierung. Mit Zeitraffung.
Naegleria gruberi belongs to the "amoeboflagellates" and occurs in two forms: as an amoeboid creeping form and as a flagellated swimming form. The creeping form is capable of encysting. After the amoeda's hatching from the cyst, the film shows its locomotion and the activity of the pulsating vacuole. We then see the flagellated swimming form and its transformation into the creeping form. After shots of the nuclear and cellular division, the film concludes with the encystment process.
