Summary
Severe malaria caused by Plasmodium malariae is rare. This case highlights rosetting as a potential factor in severe Plasmodium malariae infections, with successful treatment using quinine.
Area of Science:
- Malariology
- Infectious Diseases
- Hematology
Background:
- Severe malaria is typically associated with Plasmodium falciparum.
- Plasmodium malariae is known to cause chronic infections, but severe presentations are exceptionally uncommon.
Observation:
- A case of severe malaria in a 32-year-old Bangladeshi male is presented.
- The patient had a mono-infection with Plasmodium malariae.
- Erythrocyte rosetting, a phenomenon previously linked to Plasmodium falciparum virulence, was observed.
Findings:
- This report documents an extremely rare case of severe disease caused by Plasmodium malariae.
- The presence of rosetting in this Plasmodium malariae infection suggests a potential role in disease severity.
Implications:
- This case expands the understanding of Plasmodium malariae pathogenicity.
- It underscores the importance of considering less common Plasmodium species in severe malaria diagnoses.
- Effective treatment with intravenous quinine was achieved, indicating standard antimalarial therapies remain viable.

Malaria
Malaria pathogenesis in humans reflects a delicate interplay between parasite biology and host response. Clinical illness reflects a host’s immune response to the parasite’s asexual replication cycle, which is often asymptomatic in individuals with partial immunity. From the parasite's perspective, transmission between mosquito and human with minimal host pathology is evolutionarily advantageous. Among the six Plasmodium species infecting humans, P. falciparum and P. vivax dominate in global...
Symbiosis
Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...
Diversity of Protists II
Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...
Overview of Protists
Protists are diverse eukaryotic microorganisms that lack the specialized tissues of plants and animals and the chitinous cell walls of fungi. Their early divergence within Eukarya resulted in structural, functional, and ecological diversity. They are classified into supergroups such as Archaeplastida, Excavata, Amoebozoa, Rhizaria, Alveolata, and Stramenopiles, determined through genetic analysis and structural similarities.Structural and Functional AdaptationsProtists have various adaptations...
Toxoplasmosis
Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
Diversity of Protists IV
Amoebozoa represent a diverse group of terrestrial and aquatic protists that utilize lobe-shaped pseudopodia for locomotion and feeding. This characteristic differentiates them from the Rhizaria, which possess threadlike pseudopodia. The primary classifications within Amoebozoa include gymnamoebas, entamoebas, and the plasmodial and cellular slime molds. Phylogenetic evidence indicates that Amoebozoa diverged from a lineage that ultimately gave rise to fungi and animals.Gymnamoebas and...
