The present study aim to evaluate the potential inhibitory effect of Curcuma longa (turmeric) oil on lipophilic, yeast like fungus Malassezia furfur which causes Pityriasis versicolor disease, a common superficial fungal skin disease. The antifungal activity of turmeric oil was screened by using disc diffusion method and microdilution method. Results indicated that, in screening of turmeric oil...

background malassezia species as skin microflora of humans and other warm-blooded vertebrates are the lipophilic yeasts associated with various human diseases, especially pityriasis versicolor (pv). objectives the objective of this study was to identify the malassezia species of scraped skin of pv patients in yazd, iran, using morphological, biochemical and physiological methods. we also compar...

The present study aimed at detection and species-level identification of the Malassezia yeasts in domestic animals and aquatic birds by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Samples were collected using tape strips and swabs from 471 animals including 97 horses, 102 cattle, 105 sheep, 20 camels, 60 dogs, 30 cats, 1 hamster, 1 squirrel, 50 aquatic birds a...

BACKGROUND A type of neonatal cephalic pustulosis that is clinically similar to classic neonatal acne recently has been linked to Malassezia furfur infection. To correlate the mycological and clinical findings in neonates with cephalic pustulosis, we carried out a prospective case-control study in a neonatal unit from February to April 1997 using new techniques for classifying Malassezia specie...

The genus Malassezia includes 14 species that are found on the skin of humans and animals and are associated with a number of diseases. Recent genome sequencing projects have defined the gene content of all 14 species; however, to date, genetic manipulation has not been possible for any species within this genus. Here, we develop and then optimize molecular tools for the transformation of Malas...

A mycological medium was developed for primary isolation and culture of lipophilic yeasts. It was initially based on published information of nutrients and trace components that would promote the growth of these yeasts. It was subsequently modified and adjusted to specifically promote the growth of lipophilic yeasts and simultaneously avoid the luxurious growth of other fungi and bacteria. With...

A case of canaliculitis with obstruction of the lacrimal canaliculus and accumulation of conglomerates is described. Pityrosporum pachydermatis was cultured from the conglomerates. To the best of our knowledge this organism has not been previously implicated in such infections. Cure was obtained by treatment with nystatin administered topically and as an irrigation of the lacrimal pathways. The...

BACKGROUND The Malassezia yeasts which belong to the physiological microflora of human skin have also been implicated in several dermatological disorders, including pityriasis versicolor (PV), atopic dermatitis (AD), and psoriasis (PS). The Malassezia genus has repeatedly been revised and it now accommodates 14 species, all but one being lipid-dependent species. The traditional, phenotype-based...

During anti-Malassezia screening of plants by CLSI broth microdilution method, Cladia aggregata (Swartz) Nyl. (family Cladoniaceae), a fruticose lichen from Sikkim (northeast Himalayan region), has been found effective at minimum inhibitory concentrations (mg/mL) of 2.72, 0.63, and 1.28 against yeast-like fungi namely, M. furfur, M. globosa and M. sympodialis, respectively. These test pathogens...

The genus Malassezia comprises commensal yeasts on human skin. These yeasts are involved in superficial infections but are also isolated in deeper infections, such as fungemia, particularly in certain at-risk patients, such as neonates or patients with parenteral nutrition catheters. Very little is known about Malassezia epidemiology and virulence. This is due mainly to the difficulty of distin...
