| ABSTRACT The antifungal activity of tacrolimus in combination with antifungal agents against different fungal species has been previously reported. Here we report the in vitro interactions between tacrolimus and amphotericin B, fluconazole, itraconazole, and caspofungin against 30 clinical isolates of both fluconazole-susceptible and fluconazole-resistant Trichosporon asahii. For these analyses, we used the broth microdilution method based on the M27-A3 technique and checkerboard microdilution method. Tacrolimus showed no activity against T. asahii strains (minimal inhibitory concentrations, MICs > 64.0 µg mL−1). However, a larger synergistic interaction was observed by the combinations tacrolimus + amphotericin B (96.67%) and tacrolimus + caspofungin... |

| Dentre as propriedades biológicas da própolis, a atividade antimicrobiana tem merecido destacada atenção. Neste artigo, descreve-se a atividade antiviral de dois extratos etanólicos de própolis (EP1 e EP2) frente aos vírus: calicivírus felino (FCV), adenovírus canino tipo 2 (CAV-2) e vírus da diarréia viral bovina (BVDV). Um dos extratos (EP1) foi obtido por extração etanólica de própolis obtida da região central do Estado do Rio Grande do Sul e o segundo (EP2), obtido comercialmente de uma empresa de Minas Gerais. A análise dos extratos de própolis através da cromatografia líquida de alta eficiência (CLAE) identificou a presença de flavonóides como: rutina, quercetina e ácido gálico. A atividade antiviral bem como a citotoxicidade dos extratos aos... |

| In the present study we used two groups of Candida dubliniensis strains: one containing fluconazole-susceptible clinical isolates and another containing fluconazole-resistant laboratory derivative from the former to examine the changes on susceptibility accompanying the development of resistance to fluconazole. Our findings confirmed the ability of C. dubliniensis isolates to become resistant to fluconazole and indicated that this resistance was crossed with ketoconazole, itraconazole, ravuconazole and terbinafine. We also tested combinations of terbinafine, amphotericin B, itraconazole and voriconazole against both groups of isolates in a checkerboard assay. Surprisingly, most combinations evidenced indifferent interactions, and the best synergism... |
