Candida albicans is a significant opportunistic pathogen known for causing both superficial and systemic infections, leading to approximately 10,000 deaths annually in the U.S. This yeast exhibits several cell morphologies, including yeast, pseudohyphae, and hyphae. Environmental factors, such as serum and pH levels, significantly influence its morphogenesis. This overview discusses the yeast cell division cycle, the role of actin in cell structure, and the implications of hyphal formation, supported by light and fluorescence microscopy studies.
