White-rot fungi, unlike bacteria in conventional activated sludge system, can degrade wide varieties of textile dyes. Their large scale implementation, however, has been impeded due to lack of appropriate reactor system that can sustain stable performance under non-sterile environment. In this study, contrary to virtually complete decoloration of an azo dye (Acid Orange II, 100 mg L(-1)) in pur...

Background. Pulmonary nocardiosis (PN) is an uncommon infection often seen in immunocompromised patients. Definitive diagnosis depends on identification of the organism by culture in a patient with a clinical presentation suggestive of PN. As Nocardia can grow slowly and other infections can present similarly in the immunocompromised patient, we sought to find the performance of respiratory sam...

black meristematic fungi are cosmopolitan and able to adapt to extreme fluctuations of ultraviolet radiation, temperature, and moisture and grow in exposed habitats such as stone surfaces. in a survey on fungi associated with fruit rots, leaf spots, canker, gummosis, dieback and trunk diseases of grapevine and walnut trees in kurdistan province (iran), some black meristematic fungal isolates re...

A 70-year-old male presenting a 3-month history of genital painless erythematous nodules in the balanopreputial sulcus was referred to our service. Histopathological exam presented a chronic dermatitis with epithelioid granulomas and Grocott staining revealed numerous fungal structures with a suggestive morphology of Histoplasma sp. Cultures evidenced Histoplasma capsulatum var. capsulatum. Tre...

Building associated illnesses - sick building syndrome (SBS) as a common example - are associated with staying in buildings with poor indoor air quality. The importance of indoor fungal growth in this phenomenon continues to be evident, even though no causative relation has been established so far. Indoor humidity is strongly associated with the symptoms of SBS. Fungal metabolites that may indu...

The operational species concept, i.e., the one used to recognize species, is contrasted to the theoretical species concept. A phylogenetic approach to recognize fungal species based on concordance of multiple gene genealogies is compared to those based on morphology and reproductive behavior. Examples where Phylogenetic Species Recognition has been applied to fungi are reviewed and concerns reg...

Tinea capitis is a common fungal infection in children but rare among neonates. We present a case of a 3-week-old infant with multiple scalp lesions for 1 week. A diagnosis of tinea capitis due to Microsporum canis was made based on clinical morphology, Wood's lamp, and biopsy with a positive PAS stain. She was effectively treated with oral griseofulvin and ketoconazole shampoo.

The fungal kingdom is a hyperdiverse group of multicellular eukaryotes with profound impacts on human society and ecosystem function. The challenge of documenting and describing fungal diversity is exacerbated by their typically cryptic nature, their ability to produce seemingly unrelated morphologies from a single individual and their similarity in appearance to distantly related taxa. This mu...

In this study, based on colony morphology characteristics, a total of 19 fungal endophytes were isolated from root of Calotropis Procera a traditional Indian medicinal plant. All fungal isolates were screened for their dye degradation ability. The dyes used as test dyes were Rose Bengal (RB), azo dye Methyl Red (MR), Coomassie Brilliant Blue (CBB) and Methylene Blue (MB) and the concentration o...

Chitinases hydrolyse the beta(1,4)-glycosidic bonds of chitin, an essential fungal cell wall component. Genetic data on a subclass of fungal family 18 chitinases have suggested a role in cell wall morphology. Specific inhibitors of these enzymes would be useful as tools to study their role in cell wall morphogenesis and could possess antifungal properties. Here, we describe the crystallographic...
