Identification of Malassezia species from pityriasis versicolor in Indonesia and its relationship with clinical characteristics.
Pityriasis versicolor (PV) is a chronic superficial fungal disease caused by Malassezia spp. The incidence is as high as 30-40% in tropical climates. Previous studies indicate that the geographic factor has influence on the main species isolated from PV. Our aim was to identify Malassezia spp. from PV patients in Indonesia and their correlation to clinical characteristics. Isolates of Malassezia were collected from 98 PV patients (62 males and 36 females). Identification was based on morphological observation and biochemical evaluation. Leeming Notman agar was used as isolation culture medium. The biochemical evaluation consisted of specimen culture onto Sabouraud dextrose agar, Cremophor EL, Esculin, Dixon's agar at 37 degrees C and catalase reaction. The isolates found were Malasseziafurfur (42.9%), M. sympodialis (27.5%), M. globosa (13.3%), M. slooffiae (7.7%), M. obtusa (7.7%) and M. restricta (2.2%), and 7.14% specimens were unidentified. There was no statistically significant association between Malassezia spp. and demographic characteristics and clinical characteristics of the patients. Unlike reports from temperate climate countries, this study in Indonesia found M. furfur as the most frequently isolated Malassezia spp. in PV patients.
