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 method modified with the Alamar reage...
results the sequence analysis of the isolate confirmed as c. glabrata and deposited on ncbi genbank under the accession number no. kt763084-kt763123. the geometric mean mics against all the tested strains were as follows, in increasing order: casp (0.17 g/ml), vcz (0.67 g/ml), amb (1.1 g/ml), itz (1.82 g/ml), ktz (1.85 g/ml), and fcz (6.7 g/ml). the resistance rates of the isolates to casp, fcz...
objective: sea cucumber is a traditional food and medical item and has been reported to exhibit antioxidant, antifungal, anti tumoral and antibacterial bioactivity. the objective of this study is to describe the antibacterial activity of 4 extracts of holoturia. sp (sea cucumber), collected from hengam island of persian gulf. materials and methods: methanol, hexane, aqueous and chloroform extr...
manganese oxide nanoparticles (mn3o4-nps) were prepared using precipitation method. the prepared nanoparticles were characterized by a number of techniques, including x-ray diffraction (xrd) analysis, scanning electron microscopy (sem), transmission electron microscopy (tem) and fourier transforms infra red (ft-ir) spectroscopy. the xrd pattern showed that the structure of mn3o4-nps was tetrago...
The Epsilometer test (E test; AB Biodisk, Solna, Sweden), a new quantitative technique for the determination of antimicrobial susceptibility, was compared to reference methods (agar dilution and broth microdilution) for the antimicrobial susceptibility testing of Helicobacter pylori. Seventy-one H. pylori strains isolated from patients with duodenal ulcers were tested against 20 antimicrobial a...
MIC end points for the most commonly prescribed azole antifungal drug, fluconazole, can be difficult to determine because its fungistatic nature can lead to excessive "trailing" of growth during susceptibility testing by National Committee for Clinical Laboratory Standards broth macrodilution and microdilution methods. To overcome this ambiguity, and because fluconazole acts by inhibiting ergos...
In this study, the antifungal activities of limonene against Trichophyton rubrum were evaluated via broth microdilution and vapor contact assays. In both assays, limonene was shown to exert a potent antifungal effect against T. rubrum. The volatile vapor of limonene at concentrations above 1 µl/800 ml air space strongly inhibited the growth of T. rubrum. The MIC value was 0.5% v/v in the broth ...
In recent years, the absence of acquired antimicrobial resistance has become an important criterion to evaluate the biosafety of lactobacilli used as industrial starter or probiotic cultures. At present, however, standards for susceptibility testing of Lactobacillus strains or approved guidelines for interpreting the test results are not available. Hence, this study was carried out to contribut...
The antimicrobial susceptibilities of 100 clinical isolates of Pseudomonas aeruginosa to six antipseudomonal antibiotics were tested by five methods: the National Committee for Clinical Laboratory Standards (NCCLS) methods for broth microdilution, agar dilution, and agar disk diffusion; the Vitek Automicrobic System method (Vitek Systems, Hazelwood, Mo.); and the PDM Epsilometer test (E test) (...
