Morphological and physiological studies were carried out on a flagellate, Tritrichomonas muris, in golden hamsters. The experiments confirmed that a pseudocyst and an intermediate form exist in addition to the trophozoite in the life cycle; furthermore it was shown that the pseudocyst was the infective stage, and that a true cyst did not occur.
