Rapid AST in bloodcultures ITC precipitation after thaw-freeze cycles during transport 207776-1 the most probable explanation. Previous versions of documents Veterinary Susceptibility Testing A multicenter study was conducted to assess the accuracy of the ISO standard and the serial 2-fold dilution procedures for antifungal susceptibility testing. Comparisons between results obtained by the tray preparation method were done uso using analysis of variance ANOVA.

This article has been cited by other articles in PMC. However, preparation of ITC trays for antimicrobial susceptibility testing AST microdilution tests is associated with a significant lack of reproducibility, particularly after freezing and shipping, independent of which dilution method was followed.

Steering Committee to Presentations and statistics The greatest discrepancy was observed for the lowest concentrations and for the dilutions prepared outside Spain and shipped for concentration determinations.

Where clinical data is lacking! Projects and data submission Considering only data for dilution series prepared in Spain, no systematic difference was detected between ISO dilution and serial dilution. Calibration and validation – archive Our data showed similar precision and accuracy within each laboratory of the three procedures used for FLC microplate preparation. Development and validation of a high-performance liquid chromatography assay for posaconazole utilizing solid-phase extraction.


Quality control procedures of AST should be implemented in order to minimize the inaccuracy of dilution methods and lack of reproducibility when hydrophobic compounds such as ITC are tested.

Reference method for testing the in vitro activity of antimicrobial agents against rapidly growing aerobic bacteria involved in infectious diseases.

In addition, MIC distributions can be used to define wild type or non-wild type bacterial populations. Susceptibility testing of infectious agents and evaluation of performance of antimicrobial susceptibility testing devices. Susceptibility testing of pathogenic fungi with itraconazole: Prevalidation statistical design to assess analytical methods. This azole compound can only be ionized and solubilized in water at a very low pH, and also 207776-1 studies have indicated that poor solubilization can have a significant influence on generated MIC values You may find similar items within these categories by selecting from the choices below:.
