Microsporum nanum

Microsporum nanum is a dermatophyte fungus that is part of the Microsporum genus. It is known to cause dermatophytosis, a type of fungal infection that affects the skin, hair, and nails of humans and animals.

Overview

Microsporum nanum is a geophilic fungus, meaning it is commonly found in the soil. It is also a zoophilic fungus, as it can infect animals, particularly pigs. In humans, infection with Microsporum nanum is rare but can occur through direct contact with infected animals or contaminated soil.

Infection and Symptoms

Infection with Microsporum nanum typically results in a condition known as tinea, a type of dermatophytosis. Symptoms of tinea can include redness, itching, and scaling of the skin, as well as hair loss in affected areas. In severe cases, the infection can lead to onychomycosis, a fungal infection of the nails.

Diagnosis and Treatment

Diagnosis of Microsporum nanum infection is typically made through microscopic examination of skin scrapings or hair plucks. Treatment usually involves the use of topical or oral antifungal medications, such as griseofulvin or terbinafine.

Prevention

Prevention of Microsporum nanum infection involves good hygiene practices, such as regular hand washing and avoiding direct contact with infected animals or contaminated soil. In environments where the fungus is prevalent, such as pig farms, protective clothing and footwear may be recommended.
