  1. Tinea

  2. Ascaris

  3. Aspergillus

  4. Candida

Show answer
Correct Option: A
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'.

Show answer
Correct Option: C
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'

Correct Option: A
Explanation:

Many common skin infections are caused by different kinds of fungi like example Batrachochytrium dendrobatidis causes skin disease Therefore, (a) is the correct answer.

Name the disease which is caused by fungus.

  1. Cancer

  2. Parkinsons

  3. Typhoid

  4. Ergot

Show answer
Correct Option: D
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'

A fungal disease of humans is due to :

bio-chemistry immunology fungal diseases fungal, protozoan and worm diseases useful and harmful microbes

  1. Typhoid

  2. Trichophyton

  3. Microsporum

  4. Both B and C

Show answer
Correct Option: D
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'.

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

bio-chemistry immunology fungal diseases fungal, protozoan and worm diseases useful and harmful microbes

  1. Taenia - a tapeworm

  2. Wuchereria - a filarial worm

  3. Rhizopus - a mould

  4. Ascaris - a roundworm

Show answer
Correct Option: C
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 :

bio-chemistry immunology fungal diseases fungal, protozoan and worm diseases useful and harmful microbes

  1. Bacterium

  2. Virus

  3. Fungus

  4. Worm

Show answer
Correct Option: C
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'.

  1. Wuchereria

  2. Trichophyton

  3. Ascaris

  4. Aedes

Show answer
Correct Option: B
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.
