background and objective: reliable methods of detection of antimicrobial resistance are of paramount importance in the treatment and management of infections caused by coagulase negative staphylococci (cons). the objective of the present study was to compare and evaluate the performance of disc diffusion and e test (epsilometer test) methods for antimicrobial testing of coagulase negative staph...

a series of curcumin derivatives containing heterocyclic moiety have been synthesized and evaluated for their antibacterial activities. the chemical structures of the synthesized compounds were verified on the basis of spectral data and elemental analyses. investigation of antimicrobial activity of the derivatives demonstrated the ability to inhibit gram-positive microorganisms with zone of inh...

Two hundred and fifty tracheal aspirates were subjected to direct antimicrobial susceptibility testing by disk diffusion, Etest and inoculation on antibiotic-enriched MacConkey agar plates. Results were compared with those obtained using an automated system on microorganisms recovered from standard quantitative culture. A total of 255 microorganisms were isolated from 194 positive samples by th...

OBJECTIVE Many species of plants present noticeable potency against human bacterial and fungal pathogens. MATERIALS AND METHODS In the current study, antimicrobial activity of the fresh fruits of 4 cultivars (A to D) of Malus domestica cultivated in the Qamsar area of Kashan, Iran was investigated. The disk diffusion and minimal inhibitory concentration (MIC) evaluation antimicrobial activity...

A number of experimental methods in biology depend on the kinetics of diffusion of a substance through a gel. This paper reviews the diffusion equations, gives the experimental limitations for some useful cases, and presents computer simulations for cases that cannot be treated analytically. While double diffusion is not considered, three single-diffusion situations are treated. (1) Systems for...

antibiotic resistance of intensive care unit (icu) born aerobic gram-negative bacteria was evaluated during a six months period at a teaching hospital in tehran, and determination of the validity of the results obtained from disc diffusion tests, using discs manufactured in iran. disc susceptibility tests using iranian and standard discs (diffusion discs available in international markets) were...

disk diffusion test is the usual applicable method for assessing the antimicrobial susceptibility pattern in most institutions and hospitals. the aim of this study was to determine the reliability of resistant-reported results of disk diffusion test for 6 routinely used antibiotics against gram-positive microorganisms of nosocomial origin, using e-test method.    over a 1-year period, clinical ...

Haemophilus test medium (HTM) was developed recently for dilution and disk diffusion antimicrobial agent susceptibility testing of Haemophilus influenzae. The application of HTM to the testing of other, less frequently encountered Haemophilus species recovered from humans was evaluated in this study by using commercially prepared HTM (BBL Microbiology Systems, Cockeysville, Md.) in broth microd...
