Antifungal activity evaluation of Aloe arborescens dry extract against trichosporon genus yeasts
Provedor de dados: Acta Scientiarum: Biological Sciences
Autores: Borba, João Ricardo Bueno de Morais; Costa, Flávia da da Silva; Ishikawa, Tati; Lemes, Raquel Maria Lima.
The objective of this study was to investigate the antifungal activity of Aloe arborescens dry extract against Trichosporon genus yeast species. Extraction was carried out by means of a longitudinal incision in fresh leaves, which were collected on a vat, and the total volume was frozen and subsequently lyophilized. Then, 40 mg of the dry extract was dissolved in DMSO by gentle inversion in order to obtain a solution whose concentration was 4000 µg mL-1. This solution became limpid and slightly yellowish because the pigment of the latex was attenuated. It was performed serial dilutions from 2,000 to 15.625 µg mL-1 with RPMI-1640 broth. There was already no pigment in the first dilution of 2000 μg mL-1. It was analyzed fifteen strains of Trichosporon spp.,...

Antifungal properties of plants used in Brazilian traditional medicine against clinically relevant fungal pathogens
Provedor de dados: Brazilian Journal of Microbiology
Autores: Johann,Susana; Pizzolatti,Moacir G.; Donnici,Cláudio L.; Resende,Maria Aparecida de.
Antifungal properties of extracts from eight Brazilian plants traditionally used in popular Brazilian medicine were tested against five clinically relevant Candida species, Cryptococcus neoformans, and Sporothrix schenckii. Results demonstrate that almost all extracts exhibited antifungal activity, at least against one of the microorganisms tested. The ethanolic extract from the leaves of Schinus terebinthifolius exhibited potential antifungal activity against C. glabrata and S. schenckii. Preliminary phytochemical analysis of extract from S. terebinthifolius showed the presence of biologically active compounds, namely saponins, flavonoids, triterpenes, steroids and tannins.

Antimicrobial susceptibility testing for Helicobacter pylori isolates from Brazilian children and adolescents: comparing agar dilution, E-test, and disk diffusion
Provedor de dados: Brazilian Journal of Microbiology
Autores: Ogata,Silvio Kazuo; Gales,Ana Cristina; Kawakami,Elisabete.
Antimicrobial susceptibility testing for Helicobacter pylori is increasingly important due to resistance to the most used antimicrobials agents. Only agar dilution method is approved by CLSI, but it is difficult to perform routinely. We evaluated the reliability of E-test and disk diffusion comparing to agar dilution method on Helicobacter pylori antimicrobial susceptibility testing. Susceptibility testing was performed for amoxicillin, clarithromycin, furazolidone, metronidazole and tetracycline using E-test, disk-diffusion and agar dilution method in 77 consecutive Helicobacter pylori strains from dyspeptic children and adolescents. Resistance rates were: amoxicillin - 10.4%, 9% and 68.8%; clarithromycin - 19.5%, 20.8%, 36.3%; metronidazole - 40.2%33.7%,...
