In the study of human physiology, health, and epidemiology, identifying the exact biological classification of disease-causing organisms is essential for selecting appropriate medical interventions. Which of the following human diseases is correctly matched with its primary causative pathogen?

  1. Kala-azar (Visceral Leishmaniasis) — Protozoan parasiteCevap
  2. B
    Chikungunya — Gram-negative bacterium
  3. C
    Anthrax — Enveloped RNA virus
  4. D
    Thrush (Candidiasis) — Protozoan parasite

Cevap

Kala-azar (Visceral Leishmaniasis) is correctly matched as a disease caused by a protozoan parasite (Leishmania donovani).
The pairing of Kala-azar (Visceral Leishmaniasis) with a protozoan parasite is correct. Kala-azar is caused by protozoan parasites of the genus Leishmania (primarily Leishmania donovani in the Indian subcontinent), which target the reticuloendothelial system including the liver, spleen, and bone marrow.

Adım Adım Çözüm

1
Analyze the pathogen classification for Kala-azar
Kala-azar (Visceral Leishmaniasis) is caused by Leishmania donovani, a flagellated protozoan parasite, and transmitted to humans via the phlebotomine sandfly vector.
This establishes that the pairing of Kala-azar with a protozoan parasite is scientifically accurate.
2
Evaluate the pathogen classifications of the remaining options
Chikungunya is viral (Chikungunya alphavirus), Anthrax is bacterial (Bacillus anthracis), and Candidiasis is fungal (Candida species).
Identifying the correct biological kingdoms/types for each pathogen reveals that these three pairings incorrectly misclassify the causative agents.
