AI Article Synopsis
- Malassezia furfur is a yeast species within a larger genus consisting of 13 recognized species, with varying isolation rates found on human skin depending on geography.
- Researchers used PCR-fingerprinting to analyze M. furfur strains from Scandinavians living in Greece and compared them to strains from natives of Greece, Bulgaria, and China.
- The study revealed that M. furfur strains tended to cluster by geographic origin, suggesting a link between the yeast's variation and the host's location and skin condition, supporting its potential for further phylogeographic research.
Article Abstract
Malassezia furfur was the first species described within the cosmopolitan yeast genus Malassezia, which now comprises 13 species. Reported isolation rates of these species from healthy and diseased human skin show geographic variations. PCR-fingerprinting with the wild-type phage M13 primer (5'-GAGGGTGGCGGTTCT-3') was applied to investigate phylogeographic associations of M. furfur strains isolated from Scandinavians residing permanently in Greece, in comparison to clinical isolates from Greek, Bulgarian and Chinese native residents. Seven M. furfur strains from Scandinavians were compared with the Neotype strain (CBS1878), CBS global collection strains (n=10) and clinical isolates from Greece (n=4), Bulgaria (n=15) and China (n=6). Scandinavian, Greek and Bulgarian M. furfur strains mostly formed distinct group clusters, providing initial evidence for an association with the host's geographical origin and with the underlying skin condition. These initial data address the hypothesis that M. furfur could be a eukaryotic candidate eligible for phylogeographic studies.
