ABSTRACT Eleven antifungal drugs were tested against representative isolates of the four phylogenetic clades of the Fusarium solani species complex obtained in a multilocus sequence analysis. They all showed very poor activity, with no differences among the clades. Amphotericin B was the most active drug.

ABSTRACT The in vitro activities of amphotericin B in combination with rifampin were assessed against 95 ocular fungal isolates. The interactions between amphotericin B and rifampin at 4, 8, 16, and 32 μg/ml were synergistic for 11.8%, 51.0%, 90.2%, and 94.1%, respectively, of Fusarium solani species complex isolates and for 13.6%, 45.5%, 93.2%, and 95.5%, respectively, of Aspergillus flavus species complex isolates. Antagonism was never observed for the amphotericin B-rifampin combinations.

ABSTRACT In the treatment of disseminated Fusarium infections, amphotericin B either alone or in combination with flucytosine and rifampin is the drug therapy most frequently used. The efficacy of these antifungal drugs was evaluated in a murine disseminated-infection model, with five strains of Fusarium solani. All the treatments were clearly ineffective.

ABSTRACT The interaction of natamycin-azithromycin combination against 60 ocular fungal isolates was tested in vitro. The combination produced 100% synergistic interactions when natamycin was added to azithromycin 20, 40, and 50 μg/ml against Aspergillus flavus species complex (AFSC) isolates and to azithromycin 50 μg/ml against Fusarium solani species complex isolates. Addition of 50 μg/ml azithromycin enhanced natamycin's effect against AFSC isolates by reducing natamycin MIC90 from 64 to 0.031 μg/ml. No antagonism was observed.

ABSTRACTCyphellophora guyanensis(n= 15), otherCyphellophoraspecies (n= 11),Phialophora europaea(n= 43), and otherPhialophoraspecies (n= 12) were testedin vitroagainst nine antifungal drugs. The MIC90s across all of the strains (n= 81) were, in increasing order, as follows: posaconazole, 0.063 μg/ml; itraconazole, 0.5 μg/ml; voriconazole, 1 μg/ml; micafungin, 1 μg/ml; terbinafine, 2 μg/ml; isavuconazole, 4 μg/ml; caspofungin, 4 μg/ml; fluconazole, 8 μg/ml; amphotericin B, 16 μg/ml.
