  1. Tinea

  2. Ascaris

  3. Aspergillus

  4. Candida
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Tinea is the name of a group of diseases caused by a fungus.
  • Types of tinea include ringworm, athlete's foot and jock itch. 
  • You can get them by touching an infected person, from damp surfaces such as shower floors, or even from a pet. 
  • Hence, the Causative agent of Athlete's foot disease is Tinea.
  • So, the correct answer is 'Tinea'.

Ringworm in humans is caused by

  1. Viruses

  2. Bacteria

  3. Fungi

  4. Nematodes
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ringworm is a common fungal infection of the skin and is not due to the worm. The condition is named for the site of the body where the infection occurs. It causes a scaly, crusted rash that may appear round, red patches on the skin.
So, the correct answer is 'Fungi'

Name the disease which is caused by fungus.

  1. Cancer

  2. Parkinsons

  3. Typhoid

  4. Ergot
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Ergot is a fungal disease of cereal grasses, especially rye, caused by species of the ascomycete fungus Claviceps.
  • Typhoid fever is caused by Salmonella typhi bacteria.
  • Parkinson's disease (PD) is a neurodegenerative disorder that affects the nerve cells in the brain that produce dopamine. It is not caused by bacteria or fungi.
  • Cancer results when cellular changes cause the uncontrolled growth and division of cells, hence it is not caused by any infectious agent.

Hence answer is 'Ergot'
Multiple choice bio-chemistry immunology fungal diseases fungal, protozoan and worm diseases useful and harmful microbes

A fungal disease of humans is due to :

  1. Typhoid

  2. Trichophyton

  3. Microsporum

  4. Both B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Typhoid is an enteric fever caused by the bacterium salmonella thyphi. Hence typhoid is not a fungal disease.
  • Trichophyton is a genus of fungi, which includes the parasitic varieties that cause diseases such as tinea, including athlete's foot, ringworm, jock itch, and similar infections of the nail, beard, skin, and scalp.
  • Microsporum is a genus of fungi that causes tinea capitis, tinea corporis, ringworm diseases.
  • Hence Trichophyton and Microsporum cause fungal disease in Humans.
  • So, the correct answer is 'Both B and C'.
Multiple choice bio-chemistry immunology fungal diseases fungal, protozoan and worm diseases useful and harmful microbes

The pathogen Microsporum responsible for ringworm diease in humans belongs to the same kingdom of organisms as that of :

  1. Taenia - a tapeworm

  2. Wuchereria - a filarial worm

  3. Rhizopus - a mould

  4. Ascaris - a roundworm
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • The pathogen Microsporum responsible for ringworm disease in humans belongs to the same kingdom of organisms as that of Rhizopus - a mold(a fungus that grows in the form of multicellular filaments called hyphae)because both Microsporum and Rhizophus belong to kingdom Fungi.
  • So, the correct answer is 'Rhizopus - a mould'.

Athlete's foot disease in humans is caused by :

  1. Bacterium

  2. Virus

  3. Fungus

  4. Worm
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Athlete's foot (tinea pedis) is a fungal infection that usually begins between the toes. Athlete's foot is caused by a number of different fungi, including species of Trichophyton, Epidermophyton, and Microsporum. The condition is typically acquired by coming into contact with infected skin, or fungus in the environment.

So, the correct answer is 'Fungus'.

Ringworm infection is caused by 

  1. Wuchereria

  2. Trichophyton

  3. Ascaris

  4. Aedes
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Trichophyton is a genus of fungi which includes the parasitic diseases that cause athlete's foot, ringworm, jock itch, and similar infections of the nail, beard, skin and scalp. Dermatophytosis, also known as ringworm is a fungal infection of the skin. Typically it results in a red, itchy, scaly, circular rash. Hair loss may occur in the area affected. Ringworm can spread from other animals or between people.
