BACKGROUND Pityriasis versicolor (PV) is a mild chronic infection of the skin caused by Malassezia yeasts. Although it is primarily seen in adults, children are often affected in the tropics . METHODS Over a period of 2 years, children (up to the age of 14 years) who were clinically and mycologically diagnosed as PV were included in the study. The clinical and epidemiological pattern in diffe...

The objectives of this study were to investigate the frequency of pityriasis versicolor occurrence and to identify yeasts of the genus Malassezia in patients at the mycology laboratory of the Federal University of Goiás, in Goiânia, State of Goiás. Ninety-five cases of pityriasis versicolor were diagnosed, and four species of Malassezia were identified: Malassezia furfur, Malassezia sympodialis...

The MICs of ketoconazole and itraconazole against Pityrosporum orbiculare were 0.02 to 0.05 and 0.1 to 0.2 micrograms ml-1, respectively. In a rabbit model, orally administered ketoconazole (1 mg kg-1) afforded protection against experimental pityriasis (tinea) versicolor in all animals. Itraconazole (5 mg kg-1) was effective in four of five rabbits.

METHODOLOGY The study involved 1,387 adolescents in five public schools from June to November 2006. Participants were examined for superficia...

We report the results of a study which aim was the mycological identification of specimens coming from patients included in a clinical trial. A total of 445 specimens from patients with clinical diagnosis of dermatomicosis were processed during 8 months (138 pityriasis versicolor, 28 cutaneous candidosis and 279 dermatophytosis). A 48% of pityriasis versicolor cultures were positive for Malasse...
