However, data from Latin America remains limited. This study assessed biofilm formation and antifungal susceptibility of vaginal <i>Candida</i> isolates from Ecuadorian women. Biofilm formation at 24 and 48 h was evaluated using biomass and CFU assays and the biofilm formation index. Antifungal resistance in planktonic cells and patient microbiota profiles were also analyzed. Biofilm assessment showed 57.14% of isolates were high biofilm formers, 33.33% intermediate, 4.76% low, and 4.76% non-formers. Planktonic susceptibility testing included fluconazole, voriconazole, posaconazole, caspofungin, anidulafungin, micafungin, flucytosine, and amphotericin B. Micafungin showed the lowest MBEC90 value among tested antifungals, with an average MIC of 0.15 µg/mL, MBIC90 of 1.26 µg/mL, and MBEC90 of 1.86 µg/mL. Fluconazole followed with MIC, MBIC90, and MBEC90 values of 4.19, 63.33, and 66.59 µg/mL. Flucytosine had the highest values (MIC = 11.36 µg/mL; MBIC90 = 244.71 µg/mL; MBEC90 = 245.33 µg/mL). Both micafungin and flucytosine produced similar reductions in viable biofilm cells (1.44 log CFU), while fluconazole induced a slightly lower reduction of 1.39 log CFU.
