The MIC reflects the activity of the drug under the described test conditions, and can be interpreted for clinical management purposes by taking into account other factors, such as drug pharmacology or bacterial resistance mechanisms.

Fifty microliters of the resultant mix was injected directly into the HPLC system.

The presence and concentration of FLC or ITC in each well was determined by comparing the chromatographic signal peak area, retention time, and a UV spectral pattern of between and nm from the sample and from standard solutions. Methode de reference pour la determination de la sensibilite in vitro aux agents microbiens des uso aerobies a croissance rapide impliquees dans les maladies infectieuses. Susceptibility testing of infectious agents and evaluation of performance of antimicrobial susceptibility test devices.

In summary, our data suggest that microdilution trays for hydrophilic drugs such as FLC can be accurately prepared following the ISO recommendations or the serial 2-fold dilution schemes. Calibration and validation – archive ISO documents of relevance to antimicrobial susceptibility testing These documents are available for purchase from ISO or national standards organisations.

Susceptibility testing of moulds According to those standards and the ISO recommendations, the 2-fold dilutions of compounds should be performed in a multistep, rather complex, and time-consuming fashion, avoiding serial dilutions in order to prevent the izo of a systematic error being induced, for instance, by an imprecise pipette 9.

In vitro susceptibility tests are performed on microorganisms suspected of causing disease, particularly if the organism is thought to belong to a species that may exhibit resistance to frequently used antimicrobial agents.

Abstract A multicenter study was conducted to assess the accuracy of the ISO standard and the serial 2-fold dilution procedures for antifungal susceptibility testing.

The greatest discrepancy was observed for the lowest concentrations and for the dilutions prepared outside Spain and shipped for concentration determinations.
