Candida albicans: Molecular interactions with Pseudomonas aeruginosa and Staphylococcus aureus

Publication date: Available online 17 January 2015 Source:Fungal Biology Reviews Author(s): Allia K. Lindsay , Deborah A. Hogan The fields of mycology and bacteriology have traditionally functioned independently of each other despite the fundamental actuality that fungi and bacteria not only co-exist but also interact within several niches. In the clinical context, these interactions commonly occur within biofilms, which can be composed of single-species communities or mixed-species populations and recent studies have shown that the properties of mixed-species populations differ from those of their individual components. The interacting bacteria and fungi can exert effects on microbial behavior, dissemination, survival, the response to antimicrobials and, ultimately, patient prognosis. Microbes within biofilms exhibit increased resistance to antimicrobial agents, and a significant amount of research has thus focused on gaining an understanding of how inter-domain interactions affect biofilm formation and the response to antimicrobial therapies. Candida albicans, a commensal and opportunistic pathogen of humans, is among the fungi most frequently identified in mixed-species biofilms. Here, we review interactions between C. albicans and bacterial species with which it is commonly isolated, namely Pseudomonas aeruginosa and Staphylococcus aureus in order to look into the spectrum of biologically relevant fungal–bacterial interactions that have been described.
