ABSTRACT

@#AIM:To investigate the<i> in vitro</i> interaction between antifungals and tacrolimus acting alone or in combination against Fusarium solani.<p>METHODS: According to Clinical and Laboratory Standards Institute(CLSI)M27-Ed4 and M38-A3, 22 strains of Fusarium solani were used to perform drug sensitivity tests with chessboard microdilution method by cyclosporin A combined with 4 kinds of antifungal drugs <i>in vitro</i>.<p>RESULTS: The MIC ranges of natamycin, voriconazole, amphotericin B and fluconazole against 22 strains of Fusarium solani were 2-8, 1-8, 1-8 and 8-512μg/mL respectively. When combined with tacrolimus <i>in vitro</i>, the synergistic effects of fluconazole and Amphotericin B were observed in 64% and 41% strains respectively. There were no antagonistic effects observed in all combined drug tests. With the combination, the sensitivity of Fusarium to amphotericin B was significantly increased from 4.5% to 68.2%(<i>P</i><0.001).<p>CONCLUSION: Fusarium solani is sensitive to natamycin <i>in vitro</i> and is partially sensitive to voriconazole. When combined with cyclosporine A, it can produce synergistic effects with fluconazole and amphotericin B, and significantly increase the sensitivity of Fusarium solani to amphotericin B drugs.
