Trichophyton mentagrophytes

Structure and Physiology

Trichophyton mentagrophytes is a fungus that is part of a group known as dermatophytes.

Transmission and Disease

This fungus is known to cause a skin infection known as Dermatophytosis or Ringworm which appears on a person’s skin as an inflamed circular pattern. The invasion of the skin, hair, and nails can cause diseases such as tines pedis or athlete’s foot.


This fungus produces spores which are difficult to eliminate via disinfection. Disinfection is especially important for environments where Ringworm infections can occur and spread rapidly such as athletic facilities or schools.


T. mentagrophytes is zoonotic, meaning that it can be transferred from animals to humans.
