MAST® ICT – Indirect Carbapenemase Test

Carbapenemases are found in organisms that reside in the bowel and are often associated with high mortality rates. They are highly transmissible in healthcare settings and detection is imperative for infection control purposes. Although there are commercial solutions for the detection of carbapenemases in Enterobacteriaceae, options for Pseudomonas and Acinetobacter spp. remain limited.

MAST® has developed MAST®ICT; a paper test device, based on the principles of the Indirect

Carbapenemase Test (ICT). The ICT method utilises a cell permeabilising agent to release carbapenemase enzyme from a Carbapenemase-Producing-Organism (CPO) to hydrolyse an indicator antibiotic in the test system. This allows a normally carbapenem susceptible reporter organism to grow where antibiotic has been hydrolysed, thus producing a distorted zone of inhibition. If the test organism produces no carbapenemase, the reporter organism will form a regular, circular zone of inhibition around the indicator tip.

Features and Benefits

Detects the (Big-5-Carbapenemases)

MAST® ICT is a reliable screening tool for OXA,KPC,DNM,IMP and VIM enzymes—also known as the ‘Big-5-Carbapenemases’

Convenient format

Each device provided individually wrapped with its own desiccant, allowing the product to be used according to your personal laboratory demand.

Suitable for use with Acinetobacter, Pseudomonas spp. and Enterobacteriaceae

Simple assay for screening of problematic carbapenemase-producers, that is easy to perform and cost-effective.

Interpretation by simple observation

Distortion of the zone around Tip 3 indicates carbarpenemase-production.  No specialist equipment for interpretation.
