Biochemical and Molecular Aspects of Dimorphism in Fungi
2019Most of the eukaryotic differentiation processes are unidirectional. However, fungi have the ability to grow reversibly as unicellular yeast (Y) or as filamentous hypha (H) in response to the specific strain-dependent environmental stimuli. Such a phenomenon known as “dimorphism” is not limited to a specific class of fungi.

ON THE CELL WALLS OF DIMORPHIC FUNGI CAUSING SYSTEMIC INFECTIONS
Canadian Journal of Microbiology, 1954Cultures of the mycelial and tissue-like growth phases of Blastomyces dermatitidis, Paracoccidioides brasiliensis, Histoplasma capsulatum, and Sporotrichum Schenckii were extracted and oxidized as described by Scholl in 1908. Debye–Scherrer diagrams of the so prepared cell walls show the presence of chitin in both growth phases of each fungus ...

An Introduction to Dimorphism among Zoopathogenic Fungi
1985Many fungi have a remarkable ability to alter normal vegetative developmental sequences in response to environmental change. This ability is common among the fungi responsible for the majority of different human mycoses. With the invasion of tissue and the establishment of infection, certain fungi that are pathogenic for humans differentiate into ...

Immunological Aspects of Dimorphic Fungi in AIDS
1990The hallmark of an infection with human immunodeficiency virus (HIV) is a selective depletion of CD4+ lymphocytes and an associated progressive decline of immunological function to the point the host becomes overwhelmed by opportunistic infections or malignancies (McChesney and Oldstone, 1989; Schupbach, 1989). Since CD4+ cells are essential components

Calcium regulates in vitro dimorphism in chromoblastomycotic fungi.
Mycoses, 1994Cladosporium carrionii, Fonsecaea pedrosoi and Phialophora verrucosa, the three most important agents of chromoblastomycosis, produced large numbers of sclerotic bodies at 25 degrees C, and greater numbers at 37 degrees C, after inoculation into a defined pH 2.5 medium containing 0.1 mmol l-1 Ca2+.

Usual Susceptibility Patterns for Systemic Dimorphic Fungi
2011There are not as many requests made for in vitro susceptibility testing of systemic fungi such as H. capsulatum and B. dermatitidis. There is limited data in the literature as well. The inoculum for testing could be the yeast or conidia/mycelial form of each of these fungi. Very few laboratories offer the susceptibility test.
