Rings; accolé form

-Delicate rings

- May have two dots of chromatin

- Apliqué or accolé forms (looks like they are attached to erythrocyte membrane)

- All sizes of RBCs

Rings; multiple infection

- Delicate rings

- May have two dots of chromatin

- Apliqué or accolé forms (looks like they are attached to erythrocyte membrane)

- Multiple infection more frequent

- All sizes of RBCs

Rings

- Delicate rings

- May have two dots of chromatin

- Apliqué or accolé forms (looks like they are attached to erythrocyte membrane)

- All sizes of RBCs

Older trophozoite with Maurer's dots

- In older stages of the trophozoite

- There may appear the Maurer's dots

- They are only visible

- If there was correct pH (7.2) in the staining-solution-buffer

Macrogametocyte

- The gametocytes of P. falciparum have banana form

- The chromatin mass of the macrogametocyte is compact

- Dark red and in the center

-The cytoplasm is blue to violet

- The Pigment is concentrated round chromatin

Microgametocyte

- The gametocytes of P. falciparum have banana form

- The form is more stumpy than in the macogametocyte

- Chromatin mass larger

• More diffuse
• Loose
• Light red fragments and filaments
• Cytoplasm from violet to pink

- Always more reddish than in macrogametocyte

- Pigment is scattered.
