While mapping algal blooms from space is now well-established, mapping undesirable algal blooms in eutrophicated coastal waters raises further challenge in detecting individual phytoplankton species. In this paper, an algorithm is developed and tested for detecting Phaeocystis globosa blooms in the Southern North Sea. For this purpose, we first measured the light absorption properties of two ph...
Background and Aim: Malassezia is a lipophilic and dimorphic fungus which has different species. Some of them can be found as natural flora on the skin and in some conditions may cause seborrheic dermatitis. The aim of this study was to identify Malassezia species associated with seborrheic dermatitis in Iranian patients, using PCR-RFLP.Methods: In this study out of 79 patients with seborrheic ...
شناسایی گونههای مالاسزیای جداشده از بیماران مبتلا به پیتیریازیس ورسیکالر با استفاده از روش PCR-RFLP
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 vers...
background and objective: seborrheic dermatitis (sd) is a frequent disorder of the skin that is distinguished by the development of erythematous patches and yellow-gray scales. it is a multifactor disease that requires predisposing factors for its progress. presence of these factors leads to reproduction of opportunistic yeast malassezia spp.the aim of the present study was to isolate and ident...
the lipophilic yeasts of malassezia species are members of the normal skin microbial that are cause of pityriasis versicolor. pityriasis versicolor is a common superficial fungal infection with world-wide distribution. the phenotypic methods for identification of malassezia species usually are time consuming and unreliable to differentiate newly identified species. but dna-based techniques rapi...
Background and Objectives: Genus Malassezia comprises lipophilic yeasts which have been recognized as normal flora of the skin. Pityriasis versicolor (PV) is a common superficial infection of the stratum corneum caused by several species of Malassezia which is seen among different ages, although, this infection is more common in adolescence. The aim of this study was to determine the distribu...
background: members of the malassezia genus are often lipophilic, observed as budding yeasts and found as commensals in the skin of humans. this genus opportunistically reside in several areas including scalp where under the influence of particular predisposing factors, their proliferation is increased (e.g., high activation of sebaceous glands), and leads to dandruff and seborrheic dermatitis,...
Background and aim: Malassezia species are part of the resident skin flora of humans. These yeasts are associated with various superficial diseases, including seborrheic dermatitis, atopic dermatitis, dandruff, and psoriasis. Various DNA-based molecular methods have been recently described to differentiate species of Malassezia. In this survey, a simple, reliable, and cost effective PCR-b...
Colony enlargement in Phaeocystis globosa has been considered as an induced defense strategy that reduces its susceptibility to grazers, but allocation costs inflicted by this plastic morphological defense are poorly understood. We conducted experiments in which P. globosa cultures were exposed to chemical cues from copepods, ciliates and heterotrophic dinoflagellates, respectively, under nutri...
Background and Purpose: Lipophilic yeast of the genus Malassezia are members of normal human cutaneous micro flora which are also associated with several skin diseases. It is strongly suspected that Malassezia species are responsible for pityriasis versicolor (PV), and seborrhoeic dermatitis (SD). Considering various sensitivities among Malassezia species to antifungal, accurate species identif...
