Laboratory evaluation of phenotypic detection methods of methicillin-resistant Staphylococcus aureus

Biomedical Journal, 2014
Although conventional antibiotic susceptibility tests are most commonly performed for methicillin-resistant Staphylococcus aureus (MRSA), the results of these phenotypic tests are dependent on the standardization of the culture conditions. The aim of the

In Vitro Susceptibility Testing of Rifampin Against Acinetobacter Baumannii: Comparison of Disk Diffusion, Agar Dilution, and E-test

Erciyes Medical Journal, 2019
Objective: Resistance against a wide variety of antibiotics is one of the prominent characteristics of Acinetobacter baumannii. The purpose of this study was to investigate the in vitro susceptibility testing of A.

A Simple Disk-Diffusion Test for Differentiation of Yeast Species [PDF]

Journal of Medical Microbiology, 1985
A disk-diffusion method for identification of yeasts was developed that depended on their different but distinct susceptibilities to the following chemicals: janus green, ethidium bromide, 2, 3, 5-triphenyltetrazolium chloride, brilliant green, cycloheximide and rhodamine 6G.

A simple disk pre-diffusion test to predict in vitro aztreonam/avibactam activity against NDM-producing Klebsiella pneumoniae complex

Journal of Global Antimicrobial Resistance, 2022
: Objectives: The aim of this study was to describe a simple test to predict in vitro efficacy of aztreonam/avibactam (ATM-AVI) combination based on a pre-diffusion assay involving routinely available ceftazidime/avibactam (CAZ-AVI) and aztreonam (ATM ...

Prevalence of ESBL and AmpC genes in E. coli isolates from urinary tract infections in the north of Iran

New Microbes and New Infections, 2022
Beta-lactam resistance in Gram-negative bacteria, especially Escherichia coli, is a main clinical problem. It is often caused by the production of β-lactamases, particularly extended-spectrum β-lactamases (ESBLs) or AmpC enzymes.

Fluconazole Disk Diffusion Susceptibility Testing of Candida Species [PDF]

Journal of Clinical Microbiology, 1998
ABSTRACT We describe a simple procedure for detecting fluconazole-resistant yeasts by a disk diffusion method. Forty clinical Candida sp. isolates were tested on RPMI-glucose agar with either 25- or 50-μg fluconazole disks. With 25-μg disks, zones of inhibition of ≥20 mm at 24 h accurately identified 29 of

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Minimum inhibitory concentration values and problematic disk break points of tigecycline against vancomycin and/or high-level aminoglycoside-resistant enterococci

Alexandria Journal of Medicine, 2016
Background: Tigecycline is a new, semisynthetic glycylcycline. It is active against important multidrug resistant pathogens. Aim: The purpose of this study was to investigate the sensitivity of multidrug-resistant enterococci to tigecycline, and to test ...

Comparative Evaluation of Disc Diffusion and E-test with Broth Micro-dilution in Susceptibility testing of Amphotericin B, Voriconazole and Caspofungin against Clinical Aspergillus isolates [PDF]

Journal of Clinical and Diagnostic Research, 2015
Background: Clinical importance of Aspergillus has increased over the past few decades because of rise in immunosuppressive drugs and immune-modulating diseases.

Problems with the disk diffusion test for detection of vancomycin resistance in enterococci [PDF]

Journal of Clinical Microbiology, 1989
A total of 53 strains of enterococci, including recently isolated strains with high-level resistance to vancomycin, were tested for vancomycin susceptibility by broth microdilution and disk diffusion using Mueller-Hinton media with and without supplementation with 5% blood.
