Evaluation of Etest for susceptibility testing of multidrug-resistant isolates of Mycobacterium tuberculosis.
To prescribe effective treatment schemes for patients with tuberculosis, more-efficient susceptibility testing techniques for Mycobacterium tuberculosis are needed, especially in regions with multidrug resistance. Etest (AB BIODISK, Solna, Sweden) is a simple technique that provides quantitative drug susceptibility results for M. tuberculosis in 5 to 10 days from a culture grown at low cost. Th...
متن کاملMultisite reproducibility of Etest for susceptibility testing of Mycobacterium abscessus, Mycobacterium chelonae, and Mycobacterium fortuitum.
A multicenter study was conducted to assess the inter- and intralaboratory reproducibility of the Etest for susceptibility testing of the rapidly growing mycobacteria. The accuracy also was evaluated by comparing Etest results to those obtained by broth microdilution. Ten isolates (four of the Mycobacterium fortuitum group, three of Mycobacterium abscessus, and three of Mycobacterium chelonae) ...
متن کاملEvaluation of Etest for susceptibility testing of rapidly growing mycobacteria.
MICs of amikacin, cefoxitin, ciprofloxacin, clarithromycin, doxycycline, and imipenem were determined by Etest for 100 clinical strains of rapidly growing mycobacteria and compared with MICs determined by a reference agar dilution method. Etest MICs were also determined by an alternative inoculum application (agar overlay) method and compared with MICs determined by the inoculum application met...
متن کاملEvaluation of Etest for rapid susceptibility testing of Mycobacterium chelonae and M. fortuitum.
Etest is a new concept for MIC determinations for antimicrobial agents that is based on a predefined antibiotic gradient on a plastic strip calibrated with a continuous logarithmic MIC scale covering 15 twofold dilutions. Etest was compared with a reference agar dilution method for susceptibility testing of clinical isolates of Mycobacterium chelonae and M. fortuitum. Results read after 3 days ...
متن کاملEvaluation of the Etest for susceptibility testing of anaerobic bacteria.
We compared the susceptibility test results of 220 anaerobes against 14 antimicrobials using the Etest (AB Biodisk, Solna, Sweden) with those using the National Committee for Clinical Laboratory Standards (NCCLS) standard agar dilution method (Wadsworth version). The Etest medium was brucella blood (whole) agar and the inoculum size was equivalent to a no. 1 McFarland standard. Thirty-six perce...
