Hg/Pt hemispherical ultramicroelectrodes (UMEs) (25-microm diameter) were prepared either by electrodeposition from a mercuric ion solution or by simple contact of the Pt disk to a hanging mercury drop electrode. The two methods produced equivalent tips. Optical inspection and electrochemical characterization of these Hg tips with methyl viologen, cobalt sepulchrate trichloride, and hexaminerut...

Background and Objectives: Infection is the most common problem following burn injury. Selection and dissemination of intrinsic and acquired resistance mechanisms increase the probability of burn wound colonization by resistant species including Pseudomonas aeruginosa. Multi-drug resistant Pseudomonas ae...

Three extracts of Pulicaria dysenterica were examined for antibacterial activity using the agar disk-diffusion method against six bacterial strains. Some of these extracts were found to be active against some bacterial strains. The methanolic extract exhibited a superior level of antibacterial activity. All of the extracts were active against Vibrio chlorea.

Detection of Methicillin Resistant Staphylococcus aureus (MRSA) by CHROMagar Versus Cefoxitin Disk Diffusion Method

 Abstract Background: The disk diffusion method for identification of yeasts species was performed based on different but distinct susceptibilities of yeasts spp. to chemicals: janus green, ethidium bromide, 2,3,5-triphenyltetrazolium chloride, brilliant green, cycloheximide and rhodamine 6G. Methods: Atotal of 568 Iranian soldiers went under study for isolation and identification of Yeast spec...

Background & Aims of the Study: Methicillin-resistant staphylococcus aureus (MRSA) is considered as a major pathogen in public health concern. The objectives of this study were to firstly determine antibiotic sensitivity among Staphylococcus aureus isolated from traditional Iranian white cheese during 2015 from Hamedan province of Iran; and secondly to estimate the presence of ...

Studies were conducted to compare and evaluate antimicrobial susceptibility test results for enterococci obtained by six national committee disk diffusion procedures. Variations in the incidence of isolates in resistance categories and errors were associated with the use of ciprofloxacin, gentamicin, nitrofurantoin, rifampin, and teicoplanin in a number of committee procedures. Results indicate...

Two simultaneous Klebsiella pneumoniae outbreaks resistant to multiple antibiotics are reported. The closely related strains were distinguished by comparing the zone diameters obtained by disk diffusion susceptibility testing but not by interpretations of susceptible, resistant, or intermediate. Similar conclusions were made when minimal inhibitory concentrations were considered. The separation...
