Diversity and Antifungal Susceptibility of Malassezia spp. Isolated From Brazilian Patients With Pityriasis Versicolor and Seborrheic Dermatitis.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMalassezia spp. are part of the microbiota of many animals, including humans. However, under certain conditions, they can become pathogenic. Diseases associated with Malassezia include pityriasis versicolor (PV), seborrheic dermatitis (SD), Malassezia folliculitis, atopic dermatitis, psoriasis and fungemia.
objectiveThe present study aimed to describe the distribution of Malassezia species among Brazilian patients with PV and SD and to evaluate their susceptibility profiles to common antifungals.
methodsIn this study, 102 clinical samples from patients with PV or SD were analysed. Clinical isolates of Malassezia were identified at the species level by sequencing the D1/D2 variable domains of the large subunit rRNA gene. Antifungal susceptibility was assessed using a modified microbroth dilution method adapted for the growth of Malassezia species.
resultsAmong the 40 cultures obtained, six Malassezia species were identified. M. furfur was the most prevalent species (40.0%), followed by M. sympodialis (27.5%), M. globosa (15.0%), M. japonica (7.5%) and both M. yamatoensis and M. slooffiae (5.0% each). All isolates exhibited high MICs to caspofungin (> s16 μg/mL) and to isoconazole (MIC₅₀ = 8 μg/mL). Miconazole and clotrimazole showed MIC₅₀ values of 4 μg/mL, while itraconazole and ketoconazole were more active, with an MIC₅₀ of 0.125 μg/mL.
conclusionThis study showed the diversity of Malassezia species causing PV and SD in Brazil, including the rare species M. yamatoensis and M. japonica. These findings highlight the importance of antifungal susceptibility testing for these species to guide appropriate therapy.
