Comparative Analysis of Gradient Diffusion and Disk Diffusion with Agar Dilution for Susceptibility Testing of Elizabethkingia anophelis

Correlation of netilmicin disk diffusion susceptibility and agar dilution susceptibility.

The minimal inhibitory concentration of netilmicin determined by the agar dilution method was correlated with the disk diffusion zone of inhibition against 322 clinical isolates. Regression line analysis revealed good correlation, r = -0.90, and suggested that isolates with zone sizes </=14 mm should be considered resistant.

Comparison of Disk Diffusion, Agar Dilution, and Broth Microdilution for Antimicrobial Susceptibility Testing of Five Chitosans

ii Acknowledgements I would like to express my deep appreciation to my advisors Drs. Beilei Ge and Witoon Prinyawiwatkul, for their support, encouragement, and helpful guidance throughout my M. S. study. Their intelligence, enthusiasm, inspiration and academic perspectives impressed me immensely. Also I want to thank Dr. Zhimin Xu, as my committee member, who gave me valuable suggestions and su...

Agar-based disk diffusion assay for susceptibility testing of dermatophytes.

Currently, no agar-based susceptibility testing method has been standardized for testing dermatophytes. We describe a newly developed agar-based method employing disk diffusion assay to test the susceptibility of 47 isolates of dermatophytes against 8 antifungals. Our results show that the method is reproducible, is simple, and could be used to determine the antifungal susceptibility of dermato...

Comparison of Disk Diffusion and E-Test with the Reference Method of Microbroth Dilution for Susceptibility Testing of Acinetobacter baumannii Isolates to Tetracyclines

Abstract &nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 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 b...
