The test principle of the MICRONAUT system for antimicrobial susceptibility testing (AST) is based on phenotypic detection of resistance as expressed by microbial growth in presence of antibiotic compounds. This micro dilution procedure is a standardized method and a worldwide accepted reference system for determination of the minimal inhibitory concentration (MIC).

For all MICRONAUT AST systems the various antibiotics are placed with or without broth in a dehydrated form into the wells of the microtitration plates and are dissolved by adding bacterial suspensions. After 6 hours (rapid AST) or 18-24 hours of incubation at 35-37°C the AST plate is measured in the photometer and the test is evaluated with the MICRONAUT software or read visually.

Choose your preferred standard like EUCAST or CLSI and compose your own customised antibiogram from more than 200 antibiotics. Otherwise you can select from a wide variety of standard layouts. Take your choice, whether it’s breakpoint procedure, MIC testing or a combination of both.
