Antibiotic sensitivity of P. guilliermondii grown in presence of common antifungals on YPD agar Plate. A. P. guilliermondii showed resistance to voriconazole (VOR), griseofulvin (GRI), and miconazole nitrate (MIN), whereas mild susceptibility (<5 mm) was observed for amphotericin B (AMB) and posaconazole (POS). B. The fungal isolate showed resistance to both fluconazole (FLU) and clotrimazole (CLO), whereas detectable susceptibility was evident for nystatin (NYS) and cycloheximide (CYC), with inhibition zones of 45.0 ± 2.5 and 37.5 ± 2.3 mm, respectively. C. Caspofungin (CAP), nikkomycin Z (NIK), and terbinafine (TER) were found to be effective with inhibition zones of 22.5 ± 2.0, 20.0 ± 1.5, and 15.0 ± 1.5 mm, respectively. Experiments were carried out in triplicates and all the antifungal drugs were tested for susceptibility at a dose of 10 μg/ml.
