Kerion Celsi Caused by Nannizzia gypsea in a Two-Year-Old Child Who Had Been Hospitalized Since Birth.

Nannizzia gypsea, previously known as Microsporum gypseum, is a geophilic dermatophyte that infects humans from the soil. We isolated N. gypsea from a two-year-old girl with kerion celsi. Because of her serious medical condition, she was admitted to the pediatric ward immediately after birth. We struggled to identify the route of infection, and eventually identified her grandmother's handmade belt, which covered the endotracheal-tube-holding device, as the infection source. To prevent indirect transmission of pathogenic microorganisms from outside the hospital environment, our hospital prohibited the bringing of belongings from outside.
