Question

A fungal infection that affects nails and skin is classified as ________. 

a. systemic mycosis 

b. mycetismus 

c. superficial mycosis 

d. mycotoxicosis 

Step-by-Step Solution

Answer

The correct answer is (c) superficial mycosis 

A fungal infection that affects nails and skin is classified as superficial mycosis.  

Step1. Introduction

A mycosis is a fungal disease that results from infection and direct damage. 

There are millions of species of fungi. They live in the dirt, on plants, on household surfaces, and on your skin. Sometimes, they can lead to skin problems like rashes or bumps 

Step2. Explanation of the correct answer

A mycosis is a fungal disease that results from infection and direct damage. 

Many fungal infections are superficial; that is, they occur on the animal’s skin. They can have devastating effects. 

Fungi that cause the superficial mycoses of the epidermis, hair, and nails rarely spread to the underlying tissue. 

A fungal infection that affects nails and skin is classified as superficial mycosis.  

Step3. Explanation for Incorrect Options

a. systemic mycosis 

Systemic mycoses are caused by certain species of Deuteromycetes. The primary infection occurs in the lung and is acquired by inhaling spores or hyphae. The severity of the infection varies from a sub- clinical type to a disseminated and often fatal disease. 

b. mycetismus 

Mycetismus describes the ingestion of preformed toxins in poisonous mushrooms. In addition, individuals who display hypersensitivity to molds and spores develop strong and dangerous allergic reactions. 

 

d. mycotoxicosis 

Mycotoxicosis is the poisoning of humans (and other animals) by foods contaminated by fungal toxins (mycotoxins).
