In vivo efficacy of the ospemifene-itraconazole combination in reducing fungal burden in infected C. elegans. C. elegans strain AU37 genotype [glp-4(bn2) I; sek-1(km4) X], was infected with (a) C. albicans NR-29448, (b) C. auris 390, (c) C. neoformans NR-41298, or (d) A. fumigatus NR-35312, using an inoculum size of ~5 × 107 CFU/ml for three hours at room temperature. Infected nematodes were washed with PBS and then treated with the ospemifene (5 µg/ml)-itraconazole (1 µg/ml) combination at the respective concentration. Treatment with PBS, ospemifene, or itraconazole (ITC) alone served as controls. After 24 h of treatment, worms were lysed to determine the fungal burden (CFU/worm). *Indicates a statistically significant difference between each treatment compared to the untreated control (P < 0.05). (#) indicates a statistically significant difference between the ospemifene-itraconazole combination relative to treatment with either ospemifene or itraconazole (ITC) alone (P < 0.05), as determined by a one-way ANOVA using post-hoc Dunnet’s test for multiple comparisons.
