The fungal pathogens Cryptococcus neoformans and Histoplasma capsulatum produce melanin-like pigments in the presence of L-dopa in vitro and during mammalian infection. We investigated whether melanization affected the susceptibilities of the fungi to amphotericin B, caspofungin, fluconazole, itraconazole, or flucytosine (5FC). Using the standard macrodilution MIC protocol (the M27A protocol) o...
The feasibility of flow cytometric antifungal susceptibility testing has been studied using the fluorescent anionic membrane potential probe, bis-(1,3-dibutylbarbituric acid) trimethine oxonol [DiBAC4(3)]. The in vitro antifungal susceptibility testing of amphotericin B was performed on 8 Candida isolates from clinical specimens and 2 ATCC strains by flow cytometry with the results compared to ...
The purpose of this study was to evaluate the National Committee for Clinical Laboratory Standards agar dilution, tube dilution, and broth microdilution susceptibility tests for the measurement of teicoplanin MICs. The three standardized tests gave equivalent (within a twofold dilution) results with 98.8 to 99.0% of the 508 gram-positive clinical isolates tested, indicating that either method m...
The purpose of this study was to determine the therapeutic efficacy of citric and tartaric acids on experimental dermatophytosis in guinea pigs. In this study, the susceptibility of Trichophyton mentagrophytes var. mentagrophytes to citric and tartaric acids was assessed using the macrodilution broth method. In the animal experiments, a cream consisting of the mixed acids was topically applied ...
Background: Among important fungi associated with foods are Aspergillus spp., Penicillium spp., and Geotrichum spp. In this study, we evaluated antifungal effects of Essential Oils (EOs) of Zataria multiflora, Mentha pulegium, and Mentha piperita. Methods: Antifungal properties of EOs of M. piperita, M. pulegium, and Z. multiflora against Aspergillus spp., Penicillium spp., and Geotrichum ca...
BACKGROUND Honey has been identified as a potential alternative to the widespread use of antibiotics, which are of significant concern considering the emergence of resistant bacteria. In this context, this study aimed to evaluate the antimicrobial activity of honey samples produced by a stingless bee species and by Apis sp. against pathogenic bacteria, as well as to identify the presence of phe...
در این پژوهش مشتق تترا آزوکالیکس [4] آرن بر پایه 2 و 6- دی آمینو پیریدین به وسیله واکنش کوپلینگ آزو میان نمک تترادیازونیوم کالیکس [4] آرن و 2 و 6- دی آمینو پیریدین سنتز شده است. شناسایی ترکیب به دست آمده به وسیله روش های طیف سنجی (فروسرخ، فرابنفش، 1hnmr ، 13cnmr و جرمی) صورت گرفت. ویژگی ضد باکتری با استفاده از آزمون رقیق سازی محیط کشت (broth macrodilution) انجام شد. این بررسی روی چهار سویه استا...
Composts are widely used in horticulture as organic amendments to improve the properties of soils. have also been reported enhance disease suppressive potential soils and, therefore, could be a strategy for managing plant diseases. The aim this study was test ability amended with four different agro-industrial waste-based composts (chestnut peels and shells, spent coffee grounds, grape marc, ol...
