摘要

Candida albicans is a normal member of the human microbiota that asymptomaticallycolonizes healthy individuals, however it is also an opportunisticpathogen that can cause severe infections, especially in immunocompromisedindividuals. The medical impact of C. albicans depends, in part, on its abilityto form biofilms, communities of adhered cells encased in an extracellularmatrix. Biofilms can form on both biotic and abiotic surfaces, such as tissuesand implanted medical devices. Once formed, biofilms are highly resistant toantifungal agents and the host immune system, and can act as a protected reservoirto seed disseminated infections. Here, we present several in vitro biofilmprotocols, including protocols that are optimized for high-throughput screeningof mutant libraries and antifungal compounds. We also present protocolsto examine specific stages of biofilm development and protocols to evaluateinterspecies biofilms that C. albicans forms with interactingmicrobial partners.
