Abstract

Candida albicans, the most common pathogenic fungus, can form biofilms on the surface of medical devices and often causes bloodstream infections. Biofilms have a complex structure composed of microorganisms and a surrounding extracellular matrix. Biofilms are difficult to treat because they are resistant to antifungal drugs and the host environment. Nearly one in four patients with candidemia have a polymicrobial infection. These polymicrobial biofilms, especially those comprising cross-kingdom species of fungi and bacteria, can lead to long hospital stays and high mortality rates. This review outlines the unique interactions of dual-species biofilms with Candida albicans and the clinically important bacteria Staphylococcus aureus, Pseudomonas aeruginosa, and Escherichia coli.

Keywords: antimicrobial tolerance; bacteria; biofilm; fungi.
