Correct option is B
The correct answer is: (b) fungal
Ringworm is caused by fungi, not by worms as the name suggests.
It is a fungal infection that affects the skin, scalp, nails, and feet.
The infection is caused by dermatophytes, a type of fungus that feeds on keratin.
Common genera include Trichophyton, Microsporum, and Epidermophyton.
The condition is contagious and spreads through direct contact or contaminated surfaces.
Ringworm is also known as Tinea (e.g., Tinea corporis – body; Tinea capitis – scalp).
Dermatophytes thrive in warm and moist areas of the body.
It is treated using antifungal creams or oral medications.
Proper hygiene and avoiding shared towels/clothes can prevent infection.
Other common fungal infections: Athlete’s foot, Candidiasis, Jock itch.
Fungal diseases are eukaryotic and often more difficult to treat than bacterial infections.
Viral – Cause diseases like Influenza, Dengue, HIV; viruses are non-cellular entities.
Bacterial – Cause diseases like Tuberculosis, Typhoid, Cholera; treated with antibiotics.
Prion – Infectious proteins; cause neurodegenerative diseases like Creutzfeldt–Jakob disease.
