Abstract
Background and Aim: Malassezia is a lipophilic and dimorphic fungus which has different species. Some of them can be found as natural flora on skin and in some conditions may cause pityriasis versicolor. The aim of this study was to identify Malassezia species associated with pityriasis versicolor in Iranian patients, using PCR-RFLP.
Methods: In this study out of 65 patients with pityriasis versicolor to have pityriasis versicolor,isolates of 60 patients were positive. Malassezia species. using by PCR-RFLP. The Internal Transcribed Spacer 2 (ITS2) region was amplified by PCR employing the ITS3 and ITS4 primers and The restriction endonucleases AluI, BanI and MspAI were selected for producing distinct RFLP patterns.
Results: M. furfur (36.7%), M. globosa (30.0%), M. sympodialis (20.0%), M. slooffiae (8.3%), M. restricta (3.3%) and M. obtusa (1.7%) were the microorganisms responsible for the infection among participants. The M. sympodialis infection was strongly correlated with the female gender (P=0.02).
Conclusion: Our findings suggest that, the most common Malassezia species associated with pityriasis versicolor was M. furfur, followed by M. globosa.

Abstract
Background and Aim: Pityriasis versicolor (PV) is a fungal infection of the skin that is caused by Malassezia species in tropical and subtropical areas. Various treatments such as ketoconazole 2% shampoo are effective in the treatment of PV. In this study, the therapeutic effects of ketoconazole 2% shampoo and Octopirox 1% shampoo on PV were compared.
Methods: Fourty-two patients participated in the study. Twenty-five patients were treated using Octopirox 1% shampoo and 17 patients were treated by ketoconazole 2% shampoo. Each shampoo was administered for 5 minutes after daily showers for three weeks. At the end of the treatment period, patients were evaluated on the basis of the results KOH test and clinical examinations.
Results: At the end of the treatment period in ketoconazole 2% shampoo group, 64.7% of patients were cured. In Octopirox 1% shampoo group, 44% of patients were cured. The detected difference was not statistically significant (P=0.187).
Conclusion: Both shampoos were effective in eliminating the symptoms, but ketoconazole 2% shampoo was more effective in improving the associated hyperpigmentation and erythema than Octopirox 2% shampoo. No side effects were observed in either group.

Abstract
Malassezia species (previously Pityrosporum) are normal flora of human and warm-blooded animals skin. The genus Malassezia is now divided into 13 species. Most of the yeasts show an absolute requirement for long fatty acid chains and specific procedures are required for their isolation, conservation and identification. Under appropriate conditions, the fungi can cause various skin diseases. The aims of this review were to describe recent classification of genus Malassezia their virulence factors, and their association to dermatlogical diseases.
