Unveiling the mycobiota: The fungal frontier of human health

The microbiota and its effect on health has been extensively studied over the past decade. In many studies, the term microbiota has become synonymous with the bacterial component of the microbiota. Other microbes in the microbiota, such as viruses and fungi, have been neglected until recently. This special issue provides some background on the mycobiota and explores the role of gut fungi in human diseases such as cancer, metabolic diseases, and infection by Clostridiodes difficile , and describes the incidence of fungal infections in transplant patients. The mycobiota, once overlooked, now garners increasing attention.
