Characterization of Malassezia Species on the Healthy Skin of High School Students
The genus Malassezia includes a group of lipophilic yeasts that form part of the microbiota of the skin of humans and other vertebrates. Nevertheless, they have been related to several dermatological entities. This research proposed to characterize the morfophysiological Malassezia species isolated...
