Correlating yeast cell stress physiology to changes in the cell surface morphology: atomic force microscopic studies
Yeasts are unicellular haploid fungi that help us to bake bread and ferment alcoholic beverages, but in some cases, they can cause infections that are sometimes fatal. Over 1000 different known species of yeasts are widely distributed in nature. Although the majority of these (e.g., Saccharomyces cerevisiae) live in the general environment, a few species (e.g., Candida) are associated with humans and sometimes become pathogenic. This occurs when our immune system weakens and Candida yeasts start to grow in an uncontrolled way, thereby causing candidiasis and nosocomial infections that result in high patient morbidity and mortality rates.
