1. MRSA from Santa Catarina State, Southern Brazil: intriguing epidemiological differences compared to other Brazilian regions
Methicillin-resistant Staphylococcus aureus(MRSA) is one of the most frequently isolated agents in both nosocomial and community settings. It is a constant challenge for antibacterial therapy. Therefore, it becomes essential to understand the epidemiology of MRSA isolates in the institution and/or region to guide empirical therapy. The objective of this stud

2. Evaluation of antifungal activity of essential oils against potentially mycotoxigenic Aspergillus flavus and Aspergillus parasiticus
The antifungal activity of essential oils of fennel (Foeniculum vulgare Mill., Apiaceae), ginger (Zingiber officinale Roscoe, Zingiberaceae), mint (Mentha piperita L., Lamiaceae) and thyme (Thymus vulgaris L., Lamiaceae) was evaluated against mycotoxin producers Aspergillus flavus and A. parasiticus. High Resolution Gas Chromatography was applied to analyze

3. The potential inhibitory effect of cuminum cyminum, ziziphora clinopodioides and nigella sativa essential oils on the growth of Aspergillus fumigatus and Aspergillus flavus
The goals of this study were to evaluate the effectiveness of Cuminum cyminum, Ziziphora clinopodioides and Nigella sativa essential oils to inhibit the growth of Aspergillus fumigatus and A. flavus and to evoke ultrastructural changes. The fungi were cultured into RPMI 1640 media in the presence of oils at concentrations of 8, 6, 5, 4, 3, 2, 1.5, 1.25, 1, 0

4. Avaliação de métodos para testes de suscetibilidade in vitro de enxaguantes bucais frente a espécies do gênero Candida / Evaluation of methods for in vitro susceptibility testing of mouthwashes against species of the gender Candida
A candidíase é uma infecção fúngica oportunista freqüente, causada por leveduras do gênero Candida. A utilização de anti-sépticos como medida complementar na higiene oral é cada vez mais difundida. Sendo assim, é de grande importância a avaliação das metodologias que são utilizadas para avaliação da atividade antifúngica. A avaliação in

5. Comparison of broth macrodilution, broth microdilution, and E test antifungal susceptibility tests for fluconazole.
A comparison of the E test, the broth microdilution test, and the reference broth macrodilution susceptibility test of the National Committee for Clinical Laboratory Standards for fluconazole susceptibility testing was performed with 238 clinical isolates of Candida species and Torulopsis (Candida) glabrata. An 80% inhibition endpoint MIC was determined by t

6. Comparison of Three Reference Methods for Testing Susceptibility of Staphylococci to Trimethoprim-Sulfamethoxazole▿
Three reference MIC methods approved by the Clinical and Laboratory Standards Institute were compared by testing 567 staphylococci against trimethoprim-sulfamethoxazole. Category agreement ranged from 94.9% (broth macrodilution versus broth microdilution) to 98.6% (agar dilution versus broth microdilution). Twenty-seven strains resistant by broth macrodiluti

7. Comparison study of broth macrodilution and microdilution antifungal susceptibility tests.
An evaluation of broth dilution antifungal susceptibility tests was performed by determining both the micro- and macrodilution MICs of amphotericin B, flucytosine, fluconazole, ketoconazole, and cilofungin against 38 isolates of Candida albicans, Candida lusitaniae, Candida parapsilosis, Candida tropicalis, Cryptococcus neoformans, and Torulopsis glabrata.

8. Use of a colorimetric system for yeast susceptibility testing.
We examined the reliability and accuracy of a colorimetric assay using Alamar Blue reagent in the performance of susceptibility tests for Candida albicans. We compared the broth macrodilution method recommended by the National Committee for Clinical Laboratory Standards (NCCLS) with a macrodilution method modified with the Alamar reagent and a microdilution

9. Broth Microdilution Susceptibility Testing for Leptospira spp.
Leptospirosis in humans has traditionally been treated with penicillin or doxycycline. The choice of therapy offered at the time of initial patient presentation is often empirical, as definitive diagnosis can take weeks. Determining the activity of numerous antimicrobial agents against a wide range of Leptospira serovars may broaden empirical therapeutic opt

10. Effects of incubation time and buffer concentration on in vitro activities of antifungal agents against Candida albicans.
Nine selected isolates of Candida albicans were tested for their susceptibilities to amphotericin B and fluconazole by using three methods to assess the effect of incubation time and buffer concentration. By using a microdilution method with 0.0165 M 3-(N-morpholino)propanesulfonic acid (MOPS) and a 24-h incubation time, all of the isolates were found to be

11. Aminoglycoside resistance among Pseudomonas aeruginosa isolates with an unusual disk diffusion antibiogram.
In recent years, a number of clinical microbiology laboratories have isolated Pseudomonas aeruginosa with the unusual aminoglycoside disk diffusion result of resistance to both amikacin and gentamicin but susceptibility to tobramycin (ArGrTs). A total of 39 isolates of P. aeruginosa reported to have this resistance pattern were retested by the standard Natio

12. Comparison of the in vitro activities of the echinocandin LY303366, the pneumocandin MK-0991, and fluconazole against Candida species and Cryptococcus neoformans.
Two new glucan synthesis inhibitors, the echinocandin LY303366 and the pneumocandin MK-0991 (formerly L-743,872), were studied for their antifungal activities in vitro in relation to each other and in relation to the activity of the triazole fluconazole.
