The Sporothrix complex members cause sporotrichosis, a subcutaneous mycosis with a wide spectrum of clinical manifestations. Several specific phenotypic characteristics are associated with virulence in many fungi, but studies in this field involving the Sporothrix complex species are scarce. Melanization, thermotolerance, and production of proteases, catalase, and urease were investigated in 61...

Low levels of genetic diversity and divergence at nuclear loci have previously been observed for cycloidea and fil1-like genes within and between several Antirrhinum species, and divergence at these loci is also low between species in genera at different levels of relatedness in the former family Scrophulariaceae (Digitalis and Verbascum). The low divergence values are surprising, because (base...

BACKGROUND Although acne is a common follicular inflammatory dermatosis, studies of the relationship between Malassezia yeasts and acne have rarely been conducted. OBJECTIVE We sought to identify Malassezia yeasts from acne patients and establish a relationship between specific types of species of Malassezia and acne. METHODS Sixty acne patients were enrolled. Each strain obtained was ident...

Although the lipophilic yeasts of the genus Malassezia are part of the cutaneous microbiota in healthy individuals, they are also associated with several skin diseases, such as seborrheic dermatitis. However, the effects of age and gender on the Malassezia microbiota have not been completely elucidated. We analyzed the cutaneous Malassezia microbiota of 770 healthy Japanese using the highly acc...

The haptophyte Phaeocystis antarctica G. Karst. is a dominant phytoplankton species in the Ross Sea, Antarctica, and exists as solitary cells and mucilaginous colonies that differ by several orders of magnitude in size. Recent studies with Phaeocystis globosa suggest that colony formation and enlargement are defense mechanisms against small grazers. To test if a similar grazer-induced morpholog...

Malassezia spp. are lipid-dependent yeasts that have been related to skin mycobiota and dermatological systemic diseases. Study of lipid droplets (LDs) is relevant elucidate the unknown role these organelles in gain a broader overview metabolism Malassezia. Here, we standardized two protocols for analysis LDs M. pachydermatis globosa. The first describes co-staining confocal laser-scanning fluo...

The year 2011 has been declared the International Year of Chemistry. This is also the 100th anniversary of awarding the Nobel Prize in Chemistry to Maria Curie-Skłodowska. Maria Skłodowska, by marriage Curie, born and brought up in Poland, is one of the best known and most distinguished scientists. She is a patroness of many institutions, schools, scientific establishments, and universities not...

BACKGROUND Sporothrix species have proved to show high degrees of endemicity. Sporothrix globosa is the only pathogenic Sporothrix species that has till date been reported from China, where it is endemic in the northeastern provinces. AIMS We report two cases of lymphocutaneous sporotrichosis with diabetes mellitus as underlying disease in patients from the non-endemic area of China. METHOD...

Phaeocystis globosa blooms in eutrophication waters can cause severely damage in marine ecosystem and consequently influence human activities. This study investigated the effect and role of an algicidal actinomycete (Streptomyces sp. JS01) on the elimination process of P. globosa. JS01 supernatant could alter algal cell membrane permeability in 4 h when analyzed with flow cytometry. Reactive ox...

The phytochemical profiles and bioactivities of red, white and pink globe amaranth (Gomphrena haageana K., Gomphrena globosa var. albiflora and Gomphrena sp., respectively), much less studied than the purple species (G. globosa L.), were compared. The chemical characterization of the samples included the analysis of macronutrients and individual profiles of sugars, organic acids, fatty acids, t...
