The antibiotic susceptibility test (AST) in Clinical Microbiology laboratories is still time-consuming, and most procedures take 24h to yield results. In this study, a rapid antimicrobial susceptibility test using ATP-bioluminescence has been developed. The design of method was performed using five ATCC collection strains of known susceptibility. This procedure was then validated against standa...

The BIOGRAM (Difco Laboratories, Detroit, Mich.) system, which is designed to calculate MICs from disk diffusion zone diameters, was compared with two commercial microdilution antimicrobial susceptibility systems. A total of 111 clinical isolates were evaluated with each test system. Six additional isolates were tested in a comparison between BIOGRAM and Sceptor (Johnston Laboratories, Inc. Tow...

Standard broth microdilution (with and without bovine serum albumin [BSA] supplementation), tube dilution, and agar dilution susceptibility tests were compared for determining ramoplanin MICs. With a data base of 246 clinical isolates of gram-positive bacteria from 33 U.S. sites, it was shown that (i) agar and tube dilution susceptibility tests gave essentially the same results (93.9% of the te...

A stepped impedance resonator (SIR) based wideband bandpass filter (BPF) with a good rejection level in the extended upper stopband is presented in this article. The proposed SIR is found to have the ability to introduce two transmission poles in the passband. By appropriately selecting the impedance ratio and length ratio (α) of the SIRs, the BPF can provide a wide passband and a sharp rejecti...

Authors have proposed a new immunity/susceptibility test method. The paper describes an overview of the proposed method and some estimation results. In the method, electromagnetic fields of low-rate-rotating polarization controlled electrically and continuously in a two-dimensional plane, so that radiated immunity/susceptibility characteristics depicted threedimensionally can be obtained by usi...

abstract       background and objective: due to the continuous increase of multidrug-resistant acinetobacter baumannii strains around the world, decision making for an effective treatment of infections caused by this organism depends on the results of antimicrobial susceptibility tests. in this study, the validity of disk diffusion and e-test methods was assessed by their comparison with the re...

1. Introduction Several kinds of RF (radio frequency) radiated immunity/susceptibility test methods have been proposed, and put to practical use. The test methods using transverse electromagnetic (TEM) devices such as TEM cell and GTEM cell have already been standardized. By using these methods, the immunity/susceptibility characteristics to the electromagnetic (EM) field in a fixed direction o...
