Q.15 Match the entries in Group I with the entries in Group II
| Group I | Group II |
|---|---|
| P) Bacteria | 1) Leishmaniasis |
| Q) Virus | 2) Anthrax |
| R) Fungus | 3) Rubella |
| S) Protozoa | 4) Athletes Foot |
Correct matching is:
-
P) Bacteria → 2) Anthrax
-
Q) Virus → 3) Rubella
-
R) Fungus → 4) Athlete’s foot
-
S) Protozoa → 1) Leishmaniasis
So the right option is (C) P‑2, Q‑4, R‑3, S‑1 is incorrect; the correct pattern corresponds to P‑2, Q‑3, R‑4, S‑1, which is option (A) in the given list.
Detailed explanation of each match
Bacteria – Anthrax
-
Anthrax is an infectious disease caused by the bacterium Bacillus anthracis, a Gram‑positive, spore‑forming rod.
-
The spores can enter through skin, inhalation, or ingestion and cause cutaneous, inhalational, or gastrointestinal anthrax respectively.
Therefore, bacterial group (P) correctly matches with Anthrax (2).
Virus – Rubella
-
Rubella (German measles) is an acute exanthematous infection caused by the rubella virus, an enveloped, single‑stranded RNA virus in the genus Rubivirus, family Matonaviridae.
-
It spreads via respiratory droplets and typically presents with mild fever and a maculopapular rash, but infection in early pregnancy can lead to congenital rubella syndrome.
Thus, viral group (Q) correctly matches with Rubella (3).
Fungus – Athlete’s foot
-
Athlete’s foot (tinea pedis) is a fungal skin infection of the feet caused mainly by dermatophytes such as Trichophyton rubrum, T. mentagrophytes, and Epidermophyton floccosum.
-
It commonly produces an itchy, scaly rash between the toes and is transmitted via contaminated floors, towels, and footwear.
So fungal group (R) correctly matches with Athlete’s foot (4).
Protozoa – Leishmaniasis
-
Leishmaniasis is a disease caused by protozoan parasites of the genus Leishmania in the order Trypanosomatida.
-
These parasites are transmitted to humans by the bite of infected female phlebotomine sandflies and can cause cutaneous, mucocutaneous, or visceral forms of disease.
Therefore, protozoa (S) correctly matches with Leishmaniasis (1).
Why other options are wrong
-
Any option pairing bacteria with Leishmaniasis or Rubella is wrong because both of these are non‑bacterial: Leishmaniasis is protozoal and Rubella is viral.
-
Options that link virus with Anthrax or Athlete’s foot are incorrect: Anthrax is bacterial and Athlete’s foot is fungal.
-
Options assigning fungus to Leishmaniasis or Anthrax contradict the fact that neither disease is caused by fungi.
Only option (A) P‑2, Q‑3, R‑4, S‑1 respects the correct causal agents.
Introduction
Exam questions that ask you to match infectious agents such as bacteria, virus, fungus and protozoa with diseases like Anthrax, Rubella, Athlete’s foot and Leishmaniasis test both microbiology knowledge and logical reasoning. Understanding which organism causes which disease makes it easier to solve “match the entries in Group I with the entries in Group II bacteria virus fungus protozoa” problems quickly and accurately in competitive exams.
Group I and Group II overview
-
Group I lists broad categories of pathogens: bacteria, virus, fungus and protozoa.
-
Group II lists specific diseases: Leishmaniasis, Anthrax, Rubella and Athlete’s foot, each classically associated with one major pathogen type.
These sets can be matched one‑to‑one based on the true etiological agents.
Correct matching in table form
| Group I (Agent) | Group II (Disease) | Explanation |
|---|---|---|
| Bacteria (P) | Anthrax (2) | Anthrax is caused by the spore‑forming bacterium Bacillus anthracis. |
| Virus (Q) | Rubella (3) | Rubella is an acute infection produced by the rubella virus (Rubivirus genus). |
| Fungus (R) | Athlete’s foot (4) | Athlete’s foot or tinea pedis results from dermatophyte fungi such as Trichophyton rubrum. |
| Protozoa (S) | Leishmaniasis (1) | Leishmaniasis is due to protozoan parasites of the genus Leishmania, transmitted by sandflies. |
This table corresponds exactly to option (A) in the original question.
Quick exam tips for similar questions
-
Memorize hallmark pairs: Bacillus anthracis–Anthrax (bacterial), rubella virus–Rubella (viral), dermatophytes–tinea pedis (fungal), Leishmania spp.–Leishmaniasis (protozoal).
-
When in doubt, recall typical transmission: sandfly bites suggest protozoa, respiratory droplets usually indicate viruses like rubella, environmental spores suggest bacteria such as B. anthracis, and moist skin surfaces favor fungal infections like Athlete’s foot.
