Q. No.The diagram shows the presence of a pathogen amongst RBCs in the peripheral blood smear of a patient. Even though the shape is very easy to identify, the structure highlighted in the circle should enable you to identify the pathogen easily. It is:
| 1. | Trypanosoma | 2. | Plasmodium |
| 3. | Schistosoma | 4. | Clonorchis |
Subtopic: Â Protozoa |
