Description:This photograph depicts three nutrition test tube slant cultures, which had been inoculated with Trichophyton schoenleinii fungal organisms in order to see if the addition of thiamine (vitamin B1), had any impact upon the growth-rate of these colonies. In this case, thiamine had no impact upon the colonial growth pattern of this dermatophyte.
What are dermatophytes?

Dermatophytes are types of fungi that cause common skin, hair and nail infections. Infections caused by these fungi are also known by the names “tinea” and “ringworm.” It is important to emphasize that “ringworm” is not caused by a worm, but rather by a type of fungus called a “dermatophyte.” One example of a very common dermatophyte infection is athlete’s foot, which is also called tinea pedis. Another common dermatophyte infection affecting the groin area is jock itch, also known as tinea cruris.
