Blastomyces: Why Be Dimorphic?, Dennis J. Baumgardner
Blastomyces: Why Be Dimorphic?, Dennis J. Baumgardner
Dennis J. Baumgardner, MD
In introducing the infectious disease focus for this edition of the Journal of Patient-Centered Research and Reviews, the author describes the unsolved mysteries surrounding the dimorphic fungus Blastomyces and the related pathogenesis of pulmonary blastomycosis.

As a commensal colonizer and opportunistic pathogen, Candida albicans is the most clinically important human associated fungus. Systemic infection carries an unacceptably high mortality rate of ~40% in the growing population of immunocompromised individuals. Macrophages are important innate immune cells that limit the niches in the human body in which C. albicans can persist through phagocytic removal. However, following phagocytosis C. albicans readily escapes from the immune cell by differentiating into filamentous hyphae, a process that should be inhibited in the normally acidic phagolysosome. We have shown that C. albicans induces germination by neutralizing the phagolysosome. To better understand this …

Farnesol Signaling In Candida Albicans, Melanie L. Langford
School of Biological Sciences: Dissertations, Theses, and Student Research
Candida albicans is a polymorphic fungus that causes a range of disease in humans, from mucosal infections to systemic disease. Its ability to cause disease is linked to conversion between yeast and filamentous forms of growth, and the first quorum-sensing molecule discovered in an eukaryote, farnesol, blocks this transition. In C. albicans, farnesol also kills mating-competent opaque cells, inhibits biofilm formation, protects the cells from oxidative stress, and can be a virulence factor or protective agent in disseminated and mucosal mouse models of infection, respectively. While much emphasis has been placed on determining its effect on C. albicans morphology, …
Methods Used By Dr. R. K. Benjamin, And Other Mycologists, To Isolate Zygomycetes, Gerald L. Benny
Methods Used By Dr. R. K. Benjamin, And Other Mycologists, To Isolate Zygomycetes, Gerald L. Benny
Aliso: A Journal of Systematic and Floristic Botany
The methods that Dr. Richard K. Benjamin used to isolate Zygomycetes are discussed. These processes involved the following five steps: (1) collection, (2) plating, (3) isolation, (4) culture, and (5) maintenance. Additional methods, materials, and modifications used to isolate Zygomycetes are summarized. The author considers the flattening of the aerial hyphae onto the substrate of the faster- and higher-growing Mucorales for several consecutive days to be the critical step in isolating species of Coemansia, Piptocephalis, Syncephalis, and Dimargaritales. The methods used by other scholars to isolate, culture, and study many taxa in Zygomycetes also are discussed.
