Activities of various antifungal combinations in the setting of suboptimal posaconazole exposures in experimental pulmonary mucormycosis. Each datum point represents the log10 conidial equivalent (C.E.) lung fungal DNA. Each line represents median concentration of the treatment group. POS 10, 10 mg/kg/daily posaconazole by oral gavage (AUC/MIC, 33); DEF 10, 10 mg/kg/day deferoxamine by oral gavage; CAS 1, 1 mg/kg/day caspofungin by intraperitoneal injection; L-AMB 5, 5 mg/kg/day liposomal amphotericin B by intravenous injection; POS 80, 80 mg/kg/daily posaconazole by oral gavage (AUC/MIC, 196). Groups were analyzed using the Kruskal-Wallis test with Tukey's post hoc comparison.
