  2. Foot and mouth disease

  3. Leukoderma

  4. Proriasis


Correct Option: A

Athlete's foot is caused by?

  1. Tinea pedis

  2. Tinea capitis

  3. Rickettsia

  4. Candida albicans


Correct Option: A

What does $Claviceps$ causes?

  1. Dandruff

  2. Blindness

  3. Ergotism

  4. Angina


Correct Option: C
Explanation:

Claviceps is an ergot fungus that grows on the ears of rye and related cereal and forage plants.
Consumption of grains or seeds contaminated with the survival structure of this fungus the ergot sclerotium, can cause ergotism in humans and mammals.
So, the correct answer is 'Ergotism'

Causative agent of Athlete's foot disease is _________.

  1. Tinea

  2. Ascaris

  3. Aspergillus

  4. Candida


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'.

Causative agent of athlete's foot disease is a/an

  1. Bacteria

  2. Fungi

  3. Protozoan

  4. Echinoderm


Correct Option: B

Ringworm in humans is caused by

  1. Viruses

  2. Bacteria

  3. Fungi

  4. Nematodes


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'

Skin infections are developed because of _________

  1. Fungi

  2. Bacteria

  3. Virus

  4. None of these


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


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 :

  1. Typhoid

  2. Trichophyton

  3. Microsporum

  4. Both B and C


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 :

  1. Taenia - a tapeworm

  2. Wuchereria - a filarial worm

  3. Rhizopus - a mould

  4. Ascaris - a roundworm


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'.
