The Behavior of Trichomonas Vaginalis in a Semi-Solid Medium
Summary
- 1. In a semi-solid medium T. vaginalis sent out a long, clear pseudopodium containing the 4 anterior flagella and the undulating membrane.
- 2. This pseudopodium was in constant motion, though the trichomonas did not change its position.
- 3. The pseudopodium was frequently withdrawn into the body.
- 4. After 48 hours in the semi-solid medium a much longer pseudopodium was often formed. This could not always be withdrawn and was considered a sign of degeneration. The addition of Ringer's solution sometimes brought this form back to normal.
- 5. The axostyle with its row of granules on either side was clearly visible in these forms.
- 6. The density of the medium and the contractile tension of the protoplasm were important factors in the formation of these long pseudopodia.
