Abstract

Background And Purpose: Formation of pseudohyphae is considered a virulence factor in species. Generally, grows as budding yeast cells; however, reports illustrated that could form pseudohyphal cells in response to some stimuli. In this study, we provided insight into the ability of in forming pseudohyphal cells under different levels of carbon dioxide (CO).

Materials And Methods: reference strain (ATCC 90030) was used in this study. Yeast samples were cultured on Sabouraud dextrose broth (SDB) medium and incubated under 3%, 5%, and 10% CO levels for 24, 48 and 72 h. Control cultures were prepared without CO pressure for three days. The possibility of pseudohyphae and mycelium formation in was investigated.

Results: The results of this study revealed that the most branching filament-like cells were obtained at high CO pressure (10%) after 72 h. After three days of low CO pressure (3%), only yeast and budding cells were observed without any pseudohyphae formation.

Conclusion: CO could act as a stimulus and induced formation of pseudohyphae in yeast cells
