In this paper, we demonstrate the ability of Arabidopsis thaliana to detect different mixtures of volatile organic compounds (VOCs) emitted by the common indoor fungus, Aspergillus versicolor, and demonstrate the potential usage of the plant as a bioindicator to monitor fungal VOCs in indoor air. We evaluated the volatile production of Aspergillus versicolor strains SRRC 108 (NRRL 3449) and SRR...

BACKGROUND Pityriasis (tinea) versicolor has a high tendency to recur after being treated successfully. Prophylactic treatment to reduce recurrence is needed. OBJECTIVE To determine whether recurrence of pityriasis versicolor could be prevented by prophylactic itraconazole treatment. DESIGN Open treatment followed by a randomized, double-blind, placebo-controlled phase. SETTING Multinatio...

Cinnamaldehyde, of the genius Cinnamomum, is a major constituent of the bark of the cinnamon tree and possesses broad-spectrum antimicrobial activity. In this study, we used best multiple linear regression (BMLR) to develop quantitative structure activity relationship (QSAR) models for cinnamaldehyde derivatives against wood-decaying fungi Trametes versicolor and Gloeophyllun trabeum. Based on ...

materials and methods in total, among 134 patients clinically suspected of having pityriasis versicolor, attending the department of mycology, boali sina hospital and referral laboratory of the mazandaran university of medical sciences, 116/134 (86.5%) positive patients for malassezia elements, namely, yeast cells and short hyphae in microscopic examination, were included in the study. all 116 ...

background and objectives: the genus malassezia contains an expanding list of lipophilic yeasts involve in the etiology of various superficial fungal infections. pityriasis versicolor (pv) is the most prevalent malassezia -related infection distributed worldwide. in the present study, clinical and epidemiological features of the genus malassezia are discussed with special focus on pv in iran. m...

conclusions the nested-pcr is a rapid and repeatable method for identification of important malassezia species and this method is recommended for use on more patients. in addition the most common agents of pityriasis versicolor and seborrheic dermatitis were m. furfur and m. restricta, respectively. results the most common isolate was malassezia furfur (51.3%) followed by m. globosa (35.2%) and...

polybrominated diphenyl ethers (pbde) are widely employed as flame retardants and constitutea group of emerging pollutants of high persistence. the degradation of different pbde commercial mixtures(penta-, octa- and deca-bde) by the white-rot fungus trametes versicolor under aerobic conditions wasstudied. this work demonstrates the capacity of t. versicolor to degrade three different pbde comme...

To determine the effect of Artemisia sieberi lotion in signs & symptoms of Tinea versicolor, a randomized, double - blind clinical trial was performed comparing topical application of Artemisia sieberi lotion with Clotrimazole topical lotion, twice daily for 2 week. 60 patients suffering from Tinea versicolor completed the study. 29 patients were treated with Artemisia sieberi lotion and 31 pat...

CRP was first described in 1927 by Gougerot and Carteaud and it occurs predominantly in young adults and teenagers, affecting the neck, upper trunk and axillae with cosmetically displeasing appearance. Recognition of CRP is usually difficult by clinicians, including dermatologist as it frequently appears as pityriasis versicolor or acanthosis nigricans resulting in delay in the diagnosis [2]. H...

lipophilic yeast of the genus malassezia (pityrosporum) belongs to the normal flora of human skin and many warm-blooded animals. these fungi can produce a diverse range of diseases that the best known and most frequent of them is pityriasis versicolor, a chronic recurrent skin disease occurring primarily in tropical regions. the genus malassezia has been recently enlarged to include seven disti...
