Parasite
Plasmodium falciparum
Severe/cerebral malaria species
plaz-MOH-dee-um fal-SIP-ar-um
High-yield clue
Banana/crescent-shaped gametocytes, high parasitemia with multiple rings per red cell, and no later stages on peripheral smear are the falciparum-specific clues.
Overview
The most dangerous malaria species, responsible for severe and cerebral malaria and the highest parasite burdens. This card focuses on the falciparum-specific severe-disease and morphology vocabulary; see the generic Plasmodium card for the shared mosquito life cycle.
Classification
- Protozoa
- Apicomplexa
- Genus Plasmodium
- Most virulent malaria species
Lab & identification clues
- Banana (crescent) gametocytes on smear
- Multiple ring forms per RBC + appliqué/accolé forms
- Only rings and gametocytes seen peripherally (sequestration)
- Infects red cells of all ages -> high parasitemia
Associations
- Severe and cerebral malaria vocabulary
- Irregular/continuous fever rather than strict tertian pattern
- Microvascular sequestration/cytoadherence concept
- Widespread chloroquine-resistance framing
Commonly confused with
- Plasmodium vivax
- Babesia microti
