This review gives an update on methods available for determining (i) the susceptibility or resistance of fungal isolates or biofilms to antifungal or antibiofilm compounds and compound combinations; (ii) the in vivo efficacy of antifungal and antibiofilm compounds and compound combinations; and (iii) the in vitro and in vivo performance of anti-infective coatings and materials to prevent fungal biofilm-based infections. Methods for testing antifungal susceptibility and monitoring in vivo performance of antifungal and antimicrobial drugs are extensively described.
