MIC Test Strips

DESCRIPTION

MTS™ is a quantitative assay for determining the Minimum   Inhibitory Concentration (MIC) of antimicrobial agents against   microorganisms and for detecting the resistance mechanisms. MTS™ are paper strips with special features* that are impregnated with a predefifined concentration gradient of antibiotic, across 15 two-fold dilutions of a conventional MIC method.  On one side of the strip is indicated a MIC scale in μg/mL and a   code that identify the antimicrobial agent. For ESBL (Extended Spectrum Beta Lactamase) and MBL (Metallo Beta Lactamase) detection, the double-sided gradient carries the appropriate diagnostic reagents.   

MTS™ are available in a large variety of confifigurations.   Each confifiguration is available in packages of 10, 30 and 100 tests.

METHOD PRINCIPLE

When the MTS™ is applied onto an inoculated agar surface, the   preformed exponential gradient of antimicrobial agent is   transferred to the agar matrix.

After 18 hours incubation or longer, a symmetrical inhibition ellipse centered along the strip is formed. The MIC is read directly from the scale in terms of μg/mL at the point where the edge of the inhibition ellipse intersects the strip MTS™.

Other growth/inhibition patterns may also be seen for resistance   detection methods.
