Navigating dual-species fungal biofilms: The competitive and cooperative dynamics of Candidaalbicans.

Research on microbial biofilms has primarily concentrated on bacterial-bacterial and bacterial-fungal interactions, leaving fungal-fungal dynamics underexplored. The present study examines interactions within dual-species fungal biofilms, with a particular emphasis on Candida albicans. The behavior and pathogenicity of this yeast are significantly influenced by its interactions with other fungal species in biofilms, where its ability to shift between yeast and hyphal forms contributes significantly to biofilm formation. These fungal species biofilms exhibit a complex interplay of synergistic cooperation and antagonistic competition, depending on the environmental context and resource availability. Understanding these interactions is essential for advancing our knowledge of fungal biofilm.
