Abstract: Candida albicans is a major fungal pathogen in humans. C. albicans forms mixed-species biofilms with bacterial counterparts in various infectious diseases. The work presented in this thesis aimed to understand the molecular mechanisms governing the inter-kingdom biofilms and their clinical implications. Comprehensive OMICS biology approaches such as transcriptomics and proteomics techniques were employed to unravel the molecular pathways involved in these mixed-species biofilms. C. albicans and Streptococcus mutans mixed-species biofilms were studied as a fungal-gram positive bacterial model. S. mutans derived exoenzyme “glucosyltransferase B” (GtfB) was found to augment C. albicans in mixed-species biofilms, explaining its role in the development of early childhood caries. Frequently found in cystic fibrosis patients, C. albicans-Pseudomonas aeruginosa mixed-species biofilms were used as a model system for fungal-gram negative bacterial interactions. P. aeruginosa was able to inhibit C. albicans and the underlying molecular mechanisms revealed relevant information on enhanced virulence of these organisms in mixed-biofilms.
