Question

Identify the most infectious and fatal type of malarial parasite:

• A. Plasmodium ovale
• B. Plasmodium vivax
• C. Plasmodium malariae
• D. Plasmodium falciparum

Answer 1

The Correct Option is D

Plasmodium falciparum is responsible for the majority of severe and life-threatening cases of malaria. It is prevalent in many tropical and subtropical regions, particularly in sub-Saharan Africa. This parasite is known for its ability to rapidly multiply in the bloodstream and cause severe symptoms, leading to complications such as cerebral malaria, organ failure, and death if left untreated.

Compared to other species of Plasmodium, such as Plasmodium vivax, Plasmodium ovale, and Plasmodium malariae, Plasmodium falciparum is considered the most virulent and dangerous. It has developed resistance to certain antimalarial drugs, making treatment more challenging. Prompt and effective treatment is essential to prevent complications and fatalities associated with Plasmodium falciparum infection.

Answer 2

Among the four species of Plasmodium that cause malaria in humans: 

- Plasmodium vivax: Causes recurring malaria; less fatal.  
- Plasmodium ovale: Rare and less severe. 
- Plasmodium malariae: Causes chronic infections; not very severe. 
- Plasmodium falciparum: Most infectious and the most fatal. It can cause severe complications like cerebral malaria and multi-organ failure. 

Correct answer: Plasmodium falciparum
