Q81. Match the pathogen in Group I with the corresponding disease in Group II
| Group I | Group II |
|---|---|
| P. Bacteria Q. Virus R. Fungi S. Protozoa | 1. Measles 2. Candidiasis 3. Malaria 4. Bovine spongiform encephalitis 5. Tuberculosis |
- P-1, Q-2, R-4, S-5
- P-1, Q-4, R-2, S-3
- P-5, Q-1, R-4, S-2
- P-5, Q-1, R-2, S-3
Pathogen-disease matching questions test core microbiology knowledge for exams like NEET or CSIR NET. The correct pairing for Group I pathogens and Group II diseases is P-5, Q-1, R-2, S-3.
Correct Answer
P-5, Q-1, R-2, S-3 pairs Bacteria with Tuberculosis, Virus with Measles, Fungi with Candidiasis, and Protozoa with Malaria. This option accurately reflects standard causative agents: Mycobacterium tuberculosis (bacterium) causes TB, measles virus (paramyxovirus) causes measles, Candida species (fungus) cause candidiasis, and Plasmodium species (protozoan) cause malaria.
Group I Pathogens Overview
-
P. Bacteria: Prokaryotic microbes like Mycobacterium tuberculosis that cause TB via lung granulomas.
-
Q. Virus: Obligate intracellular parasites; measles virus spreads via respiratory droplets.
-
R. Fungi: Eukaryotic pathogens like Candida albicans, causing opportunistic infections.
-
S. Protozoa: Single-celled eukaryotes; Plasmodium transmitted by mosquitoes.
Option Analysis
Option P (Bacteria) Q (Virus) R (Fungi) S (Protozoa) Correct? Reason 1. P-1, Q-2, R-4, S-5 Measles Candidiasis BSE TB No Measles is viral, not bacterial; TB is bacterial, not protozoan . 2. P-1, Q-4, R-2, S-3 Measles BSE Candidiasis Malaria No BSE is prion (not virus); measles not bacterial . 3. P-5, Q-1, R-4, S-2 TB Measles BSE Candidiasis No BSE is prion disease from misfolded proteins, not fungal . 4. P-5, Q-1, R-2, S-3 TB Measles Candidiasis Malaria Yes Matches all: bacterial TB, viral measles, fungal candidiasis, protozoan malaria . Disease-Pathogen Details
Tuberculosis (5): Caused by bacterial M. tuberculosis, airborne spread leads to lung infection.
Measles (1): Viral, causes rash and fever; vaccine-preventable.
Candidiasis (2): Fungal overgrowth, often oral/thrush in immunocompromised.
Malaria (3): Protozoan Plasmodium via Anopheles bite.
BSE (4): Prion disease in cattle (mad cow), not matching any group. -
