A) Corynebacterium

B) Microsporum

C) Clostridium

D) Salmonella

Answer 1

Hint: It is a fungus which is known as dermatophytes. It infects the layers of the upper and dead skin.

Complete answer:

To answer this question, first, we need to know about disease and how it causes it. The term ‘disease’ means uncomfortable or disturbed ease. It is a departure from the state of health. Thus, the disease can be defined as ‘the malfunctioning of the body or a part of it due to one reason or the other’. Diseases are caused due to agents. These agents may be biological agents or pathogens, physical agents, chemical agents, and nutrient agents. Ringworm is caused by biological agents.

Now lets us find the solution from the given options-

Corynebacterium is a bacterial disease which causes diphtheria. This bacterium makes a toxin that can cause people to get very sick.

Microsporum is a fungal disease that causes ringworm. This disease causes appearance of scaly, dry lesions on various parts of the body. These lesions are accompanied by intense itching.

Clostridium is a bacterial disease that causes food poisoning. This bacterium makes a toxin that can cause diarrhea.

Salmonella is a bacterial disease that causes typhoid i.e enteric fever. 

Thus, the right answer is option B i.e., Microsporum.

Additional information:

The ringworm involved in the bearded areas of the face and neck is said as Tinea barbae. The ringworm of foot is said as Tinea pedis. And the ringworm of the scalp is said as Tinea capitis.

Note:  Microsporum is a fungal disease which can be said to be dermatophytes as it infects skin, and hairs. These fungal infections can be observed in both animals and humans
