True about peripheral blood smear of malaria are all except?
**Core Concept**
Malaria peripheral blood smear examination is a crucial diagnostic tool for identifying the Plasmodium species causing the infection, based on the morphology of the parasites and the host cells they infect.
**Why the Correct Answer is Right**
The peripheral blood smear of malaria shows distinctive features specific to each Plasmodium species. For instance, Plasmodium falciparum trophozoites exhibit a "sickle" or "banana" shape, while Plasmodium vivax trophozoites have a "band" or "bread loaf" appearance. The presence of gametocytes, which are the sexual stages of the parasite, can also help in identifying the species.
**Why Each Wrong Option is Incorrect**
**Option A:** Incorrect because this statement is true about the peripheral blood smear of malaria. However, the question asks for the exception.
**Option B:** Incorrect because this statement is a true characteristic of the peripheral blood smear of malaria, particularly for Plasmodium falciparum.
**Option C:** Incorrect because this statement is also true for the peripheral blood smear of malaria, specifically for Plasmodium vivax.
**Clinical Pearl / High-Yield Fact**
When interpreting the peripheral blood smear of malaria, it's essential to look for the morphology of the parasites and the host cells they infect, as this can help in identifying the Plasmodium species causing the infection. This knowledge can guide treatment decisions and improve patient outcomes.
**Correct Answer:** A.
