BACKGROUND & OBJECTIVE Conventional methods to detect methicillin resistance in Staphylococcus aureus are inadequate as expression of resistance is subject to environmental and conditional expression of PBP2a antigen. The objective of the present study was to determine methicillin resistance in S. aureus by conventional susceptibility (oxacillin disc diffusion and oxacillin MIC) and molecular m...

The present study aimed to evaluate antimicrobial activity of tigecydcline against 84 multidrug resistant (MDR) Acinetobacter spp. strains by disc diffusion and E-test methods. The results of disc diffusion test were compared according to two different interpretation ways. In addition, E-test results and the disc diffusion results that interpreted by both the methods were checked for compatibil...

The emergence of new infectious diseases, the resurgence of several infections that appeared to have been controlled and the increase in bacterial resistance have created the necessity for studies directed towards the development of new antimicrobials. Considering the failure to acquire new molecules with antimicrobial properties from microorganisms, the optimization for screening methods used ...

Background: Once identified as Staphylococcus aureus, it is imperative to understand their methicillin resistance status for institution of appropriate therapy. Conventional disc diffusion tests may not accurately identify MRSA strains and may not be in concordance with PCR results. Objectives: Relative abilities of phenotypic and molecular methods to detect MRSA strains was evaluated to unders...

introduction : due to the importance of laser light penetration and propagation in biological tissues, many researchers have proposed several numerical methods such as monte carlo, finite element and green function methods. among them, the monte carlo method is an accurate method which can be applied for different tissues. however, because of its statistical nature, monte carlo simulation requi...

Ampicillin-sulbactam (A/S) and amoxicillin-clavulanic acid (AUG) are thought to be equally efficacious clinically against the Enterobacteriaceae family. In this study, the in vitro activities of the A/S and AUG were evaluated and compared against Escherichia coli and Klebsiella spp. Antimicrobial susceptibility tests were performed by standard agar dilution and disc diffusion techniques accordi...

BACKGROUND Detailed fluorescein angiographic findings in the disc circumference may be useful for evaluating the possible relation of the circumference to glaucomatous nerve damage. METHODS Fluorescein angiograms of 25 eyes of 25 subjects with primary open angle glaucoma were observed after they had undertaken Octopus perimetry. Based on the retinotopic projection, disc sectors and correspond...
