| Cryptococcus spp. are common causes of mycoses in immunocompromised patients. To determine the drug susceptibilities of clinical Cryptococcus spp. isolates, the characteristics of 61 clinical Cryptococcus spp. complex isolates and their antifungal susceptibilities were investigated, including 52 C. neoformans and 9 C. gattii isolates collected at Shanghai between 1993 and 2009. Antifungal susceptibility of clinical isolates to amphotericin B, fluconazole, itraconazole, and flucytosine were determined by the microdilution method M27-A2 and the ATB FUNGUS 3 kit. The 90% minimum inhibitory concentration (MIC90) and susceptibility ranges were as follows: 1 (0.0625-1) µg/mL for amphotericin B, 4 (0.125-16) µg/ mL for fluconazole, 0.25 (0.0313-4) µg/mL for... |

| Causative agent in majority of VVC is Candida albicans, but infection due to non-C. albicans is common. Use of empiric antifungal therapy in Brazil due to syndromic management of vulvovaginitis could act as risk factor for increase resistance among VVC causative agents. From Mato Grosso patients, 160 with culture-proved among 404 women who had clinical symptoms of VVC, were enrolled in this study. 70 non-pregnant women and 90 pregnant women were included. Candida albicans was the most prevalent, representing 72.9% in the non-pregnant group and 92.3% in the pregnant group. Differences in species distribution were noted between the two groups, being C. parapsilosis the second more prevalent species among non-pregnant women. Susceptibility testing revealed... |

| Malassezia pachydermatisis associated with dermatomycoses and otomycosis in dogs and cats. This study compared the susceptibility of M. pachydermatis isolates from sick (G1) and healthy (G2) animals to azole and polyene antifungals using the M27-A3 protocol. Isolates from G1 animals were less sensitive to amphotericin B, nystatin, fluconazole, clotrimazole and miconazole. |

| In this work we studied the susceptibility to heat and antifungal agents of the first strains of environmental Cryptococcus neoformans var neoformans (serotype D) isolated in the state of Rio Grande do Sul, Brazil. In order to achieve a rigorous analysis, we employed the methodology recommended by NCCLS, Yeast Nitrogen Base (YNB) proposed by Ghannoum et al (YNB-1), Antibiotic medium 3 (AM3) indicated by others, YNB adjusted to the NCCLS methodology (YNB-2) and Etest. Our results indicate that all strains were susceptible to amphotericin B (0.0625-0.5 µg/mL), fluconazole (0.125-8.0 µg/mL), itraconazole (0.031-0.25 µg/mL) and flucytosine (0.125-4.0 µg/mL). The C. neoformans serotype D strains were more susceptible to heat (47ºC/30 min) than C. neoformans... |

| This study compared the performance of three culture media used for the determination of minimal inhibitory concentration (MIC) of amphotericin B and fluconazole against 48 Cryptococcus neoformans strains. For amphotericin B the media employed were RPMI 1640 medium, as indicated by NCCLS as reference, Yeast Nitrogen Base (YNB) as proposed by Ghannoum et al. (YNB-1), Antibiotic medium 3 (AM3) indicated by others, and YNB as proposed by us (YNB-2). In YNB-1, amphotericin B showed broader MIC ranges, varying from 0.125 µg/ml to 1.0 µg/ml; in RPMI 1640 medium and YNB-2 the MICs were similar and in AM3 the MIC ranges were narrower. The same pattern was observed for MIC 90%. For fluconazole the media employed were RPMI 1640 and YNB-1. The MIC ranges were broader... |

| Denture stomatitis is an inflammatory condition that occurs in denture wearers and is frequently associated with Candida yeasts. Antifungal susceptibility profiles have been extensively evaluated for candidiasis patients or immunosupressed individuals, but not for healthy Candida carriers. In the present study, fluconazole, itraconazole, voriconazole, terbinafine and 5-flucytosin were tested against 109 oral Candida spp. isolates. All antifungal agents were effective against the samples tested except for terbinafine. This work might provide epidemiological information about Candida spp. drug susceptibility in oral healthy individuals. |

| This study investigated the prevalence of C. dubliniensis in a Brazilian family with an HIV - infected child. A total of 42 oral isolates were obtained from eight family members. The identification of C. dubliniensis was performed by polymerase chain reactions (PCR) using primers against a specific sequence of the C. dubliniensis cytochrome b gene. Only the HIV-infected child and his grandmother were colonized by C. dubliniensis. In this study C. dubliniensis isolated from the HIV-infected child exhibited high susceptibility for azoles tested with MICs of 0.125 and 0.5 µg/mL for voriconazole and fluconazole, respectively. Accumulation of [³H] fluconazole in C. dubliniensis isolated from the HIV-infected child was slightly reduced in comparison to the... |

| Several studies have reported the occurrence of infections caused by Candida yeasts as well as the increasing prevalence of non albicans species. The aim of the present work is focused on the obtaining of heteroresistance to amphotericin B and fluconazole in Candida species using two distinct methodologies: selection and induction. Resistant samples were obtained by selective pressure using a medium with fluconazole for growth, followed by growth in a medium with amphotericin B. The selective pressure was also created beginning with growth in amphotericin B medium followed by growth in fluconazole medium. Concomitantly, samples were submitted to the induction of resistance through cultivation in increasing concentrations of fluconazole, followed by... |

| The in vitro activity of antifungal and antiseptic agents were evaluated against dermatophytes isolated from patients with tinea pedis. The antifungals studied were: ciclopirox olamine, cetoconazole, tolciclate and terbinafine, and the antiseptics were: povidine iodine (PVPI), propolis, Fungol®, Andriodermol®, and boric acid. The minimum inhibitory concentration (MIC) or the minimal dilution concentration (MDC) was determined by an agar dilution method using modified yeast nitrogen agar base, and the minimum fungicidal concentration (MFC) or minimum fungicidal dilution (MFD) was determined with subcultures on Sabouraud dextrose agar. All drugs studied were active against the dermatophytes at lower concentrations than those used in products and/or... |
