Direct Disk Diffusion Susceptibility Testing for Staphylococcus aureus from Blood Cultures: Diagnostic Accuracy and Impact on Antimicrobial Stewardship

Direct Disk Diffusion Susceptibility Testing for Gram-negative Bacteria from Blood Cultures: Diagnostic Accuracy and Impact on Antimicrobial Stewardship

Antimicrobial Susceptibility Pattern of Staphylococcus aureus Strains Isolated from Hospitalized Patients in Tehran, Iran

     Staphylococcus aureus is a major bacterial pathogen that causes different community- and hospital-acquired infections. Over time, strains of S. aureus have become resistant to different antibiotics including penicillinase-resistant penicillins. Having data on the local antimicrobial susceptibility pattern of this pathogen is necessary for selection of appropriate...

Comparison of Disc Diffusion and E test methods for Antimicrobial Susceptibility Testing Of Vancomycin in Coagulase Negative Staphylococcus Isolated from Blood Culture

  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 ne...

Frequency of Pathogens and Antimicrobial Susceptibility of Bacteria Isolated from Bloodstream Infections

  Background and Objectives: Blood stream infections cause significant morbidity and mortality in the world. In this study, we aimed at describing the organisms responsible for septicemia in 2006-2007 and their antimicrobial susceptibility that might lead to proper selection of antimicrobial agents in hospitalized patients with suspected sepsis. Materials and Methods: Microbiology reports of ...

Reliability of Disk Diffusion Test Results for the Antimicrobial Susceptibility Testing of Nosocomial Gram-positive Microorganisms: Is E-test Method Better?

   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, clinic...
