“…Multi-country studies are necessary for accessing microbial variation due to genetic factors, socioeconomic status and cultural features, as well as addressing issues of particular interest of each country. Human microbiome research in Brazil has progressed recently 10 , but it requires more effective public policies for supporting individual research groups and local consortia initiatives. Finally, bridges should be constructed to connect scientific research and clinical practice, accelerating knowledge transfer and converting it into new possibilities for diagnostics, therapy, and prevention of diseases.…”

Despite recent advances, to date there is not full knowledge of microbial diversity inhabiting various organs of human body. Skin harbors a complex microbiome that might affect our health positively and negatively. Fungal communities from skin are dominated byMalasseziayeasts. Traditionally, they were thought to be causative agents of skin diseases; however, their role is controversial, and the possible implication of specific species and subtypes remains unclear. Previously, we have conducted two fungal community surveys in healthy skin and dandruff/sebohrreic dermatitis, and have detected prevalentMalasseziaorganisms that could not be assigned to any known species. The usage of distinct ITS rDNA regions did not allow sequence comparison between studies. Here we report molecular characterization and phylogenetic analysis of unidentifiedMalasseziaorganisms, aiming to increase knowledge in fungal microbiome from skin. Findings suggested that a highly prevalent organism might belong to a novelMalasseziaspecies. Results also revealed uncertain taxonomic assignments, even in the case of accepted species. Correct assignment of species and intraspecific variants is relevant considering that specific taxa might be directly involved in disease development. Despite high prevalence, organisms might have remained undiscovered due to difficulties in culturingMalassezia. Challenges and future perspectives for skin fungal microbiome studies are discussed. We address issues to be overcome for unraveling the complete skin microbial diversity and its relation to health and disease.
