Persistent or recurrent oropharyngeal candidosis (OPC) caused by Candida albicans is common in patients with AIDS. Fluconazole has been used widely to treat OPC, but several publications have described its failure in the treatment of patients with advanced AIDS, particularly when used over a long period of time. 3 The Subcommittee for Antifungal Susceptibility Testing of the National Committee ...

Background and objectives: Persian scholars such as Avicenna and Zakariya al-Razi have pointed out many uses for henna oil. The present study aimed to propose a method for standardization of this oil. Methods: The luteolin content has been evaluated quantitively by HPTLC method to standardize the henna oil. The oil sample was applied on silicagel plate and the ...

The feasibility of using a capacitance method (CM) for direct antifungal susceptibility testing of yeasts in positive blood cultures was evaluated. The CM used the same test conditions as those recommended by the National Committee for Clinical Laboratory Standards. After direct inoculation of positive culture broths into module wells (Bactometer; bioMérieux, Inc., Hazelwood, Mo.), the end-poin...

Penicillium chrysogenum was isolated from three subsequent cerebrospinal fluid (CSF) specimens of a 73-year-old male patient without immunological compromise. The isolated was tested against five antifungal agents according to the NCCLS M38-P macrodilution method. MICs were determined as follows: amphotericin B (AMB), 2 microg ml(-1); fluconazole (FLZ), 8 microg ml(-1); itraconazole (ITZ), 1 mi...

A 25-microg fluconazole disk diffusion test using a Mueller-Hinton agar plate containing 2% glucose and 5 microg of methylene blue/ml (GM-MH) was compared to the macrodilution reference method for 210 Candida species. The GM-MH agar plate was read at 24 h. The predictive values of disks with susceptible, intermediate, and resistant results on the GM-MH agar plate at 24 h were 97.1, 56.3, and 76...

the adsorption study was conducted on three japanese soils with different soil properties to characterize the adsorption pattern of arsenic (as). double tube method was used to find out the effect of soil moisture levels on as adsorption. for this study, besides double tube method, conventional batch method also was used. the as adsorption showed two phase kinetics. an initial and rapid adsorpt...

This study evaluated the following methods for determining nitrate utilization: Wickerham broth, a special nitrate broth, Delft plate, and nitrate strip. With 236 isolates of cryptococci as test organisms, the special nitrate broth method gave 99% correct results and the Wickerham broth method gave 98%. The nitrate strip and Delft plate methods gave correct results in 94 and 86% of tests, respe...

A new medium designated as D streptococcus-enterococcus broth was formulated and evaluated for the enrichment and isolation of strains of serological group D streptococci. This medium was made by modifying Todd-Hewitt broth. Most-probable-number multiple-tube and membrane filter techniques were employed to estimate the numbers of enterococci in known cultures, wastewater, and other samples. Pre...

A dissolved methane sensor based on silicone tube was designed, constructed and optimized.The silicone tube diameter, silicone tube length and helium flow rate (as the carrier gas(were considered as process parameters to be optimized.A continuous stream of helium (50 mL/min) was directed through the tubing, sweeping out the...

Introduction: Hemolytic streptococci are one of the most frequent human pathogens capable of producing a variety of diseases ranging from pharyngitis, impetigo, to more severe and life threatening diseases like Toxic Shock Syndrome, neonatal sepsis, pneumonia and meningitis. Though they are still susceptible to commonly used antibiotics, resistance is increasingly reported. Materials and Method...
