This report presents a semisolid agar antifungal susceptibility (SAAS) method for the rapid susceptibility screening of yeasts and molds. The reproducibility and accuracy of the SAAS method were assessed by comparing the MICs of amphotericin B and fluconazole obtained for 10 candidate quality control (QC) American Type Culture Collection yeast strains in >/=15 replicates with those found by six...

Background & Aims of the Study: Rhodococci according to possess large genome, their active metabolism and survival under extreme conditions, are highly regarded for biodegradation and bioremediation of different pollutants especially heavy metals in the environment. Biofilms are more resistant to heavy metals than free-swimming organisms. The aim of this study was biofilm forma...

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 dissolved methane which diffused through the walls of the tubing from t...

conclusions: the results showed that silver nanoparticles have an antimicrobial effect against intramacrophage b. abortus 544. results: the well diffusion agar study showed that silver nanoparticles have an antimicrobial effect on b. abortus 544. the mic and mbc of silver nanoparticles against b. abortus 544 were; 6 ppm and 8 ppm, respectively. the silver nanoparticles showed antibacterial effe...

The MTT method for rifampicin and isoniazid susceptibility testing of Mycobacterium tuberculosis was developed by using bacterial suspension prepared from colonies on solid media. The MTT tube assay in 1 ml Middlebrook 7H9 broth was completed within 4 days for rifampicin (RMP) and within 7 days for isoniazid (INH). When MTT assay results with 279 M. tuberculosis clinical isolates were compared ...

Broth (Albimi) containing 2 per cent "M" peptone, 0.1 per cent glucose, 0.2 per cent yeast autolysate, 0.5 per cent NaCl, and 0.01 per cent sodium bisulfite was the medium used. Four and one-half ml of medium were added to each tube, sterilized for 15 min at 15 lb pressure, and the tubes of media, after inoculation, were incubated at 37 C in air or under varying amounts of carbon dioxide. Three...
