Many microbial pathogens form biofilms, assemblages of polymeric compounds that play a crucial role in establishing infections. The biofilms of species also contribute to high antifungal resistance. Using our collection of 29 clinical isolates, we focused on characterizing differences in thermotolerance, anaerobic growth, and biofilm formation across four species complexes commonly found in clinical settings.

Article Synopsis
  • Hfl1p is an important protein in an opportunistic fungal pathogen that helps it thrive in nutrient-poor conditions and contributes to its ability to cause infections.
  • Previous research indicated Hfl1p's involvement in mitochondrial ATP production and the transformation of yeast into hyphal forms, but its specific functions in virulence behaviors were still not fully understood.
  • The study used proteomic analysis to demonstrate that Hfl1p plays a significant role in mitochondrial function, energy metabolism, and shape-shifting of the fungus, which is crucial for its pathogenic abilities and may provide new targets for treatment strategies.

How mutations in mitochondrial electron transport chain (ETC) proteins impact the cell cycle of Candida albicans was investigated in this study. Using genetic null mutants targeting ETC complexes I (CI), III (CIII), and IV (CIV), the cell cycle stages (G0/G1, S phase, and G2/M) were analyzed via fluorescence-activated cell sorting (FACS). Four CI null mutants exhibited distinct alterations, including extended S phase, shortened G2/M population, and a reduction in cells size exceeding 10 µM.

Background: The study of health-related quality of life in survivors of gynecologic cancers is becoming increasingly important as 1.5 million survivors of gynecologic cancer in the United States and more are expected due to advances in diagnosis and treatment. This project investigated the perceived needs and lived experiences of survivors of gynecological cancer to help design supportive activities to be implemented in clinical practice.

Loss of respiratory functions impairs Candida albicans colonization of host tissues and virulence in a murine model of candidiasis. Furthermore, it is known that respiratory inhibitors decrease mannan synthesis and glucan exposure and thereby promotes phagocytosis. To understand the impact of respiratory proteins of C.
