Time-lapse mesoscopy of Candida albicans and Staphylococcus aureus dual-species biofilms reveals a structural role for the hyphae of C. albicans in biofilm formation

Katherine J. Baxter, Fiona A. Sargison, J. Ross Fitzgerald…·Paul A. Hoskisson

The paper uses time-lapse mesoscopy to study dual-species biofilms of Candida albicans and Staphylococcus aureus, showing that C. albicans morphology affects biofilm structure and infection synergy.
