Antimicrobial Susceptibility Testing for Three Malassezia Species
The Malassezia genus comprises lipid-dependent yeasts that have long been associated with common skin diseases, and have recently been linked with Crohn’s disease and certain cancers. Understanding Malassezia susceptibility to diverse antimicrobial agents is crucial for identifying effective antifun...

description | The Malassezia genus comprises lipid-dependent yeasts that have long been associated with common skin diseases, and have recently been linked with Crohn’s disease and certain cancers. Understanding Malassezia susceptibility to diverse antimicrobial agents is crucial for identifying effective antifungal therapies. Here, we tested the efficacy of isavuconazole, itraconazole, terbinafine, and artemisinin against three Malassezia species: M. restricta, M. slooffiae, and M. sympodialis. Using broth microdilution, we found antifungal properties for the two previously unstudied antimicrobials: isavuconazole and artemisinin. Overall, all Malassezia species were particularly susceptible to itraconazole, with a MIC range from 0.007 to 0.110 μg/mL. IMPORTANCE The Malassezia genus is known to be involved in a variety of skin conditions and has recently been associated with diseases such as Crohn’s disease, pancreatic ductal carcinoma, and breast cancer. This work was completed to assess susceptibility to a variety of antimicrobial drugs on three Malassezia species, in particular Malassezia restricta, which is an abundant Malassezia species both on human skin and internal organs and has been implicated in Crohn’s disease. We tested two previously unstudied drugs and developed a new testing method to overcome current limitations for measuring growth inhibition of slow-growing Malassezia strains. |
