Bruker Announces Acquisition of MERLIN to Add Selected Antibiotic Resistance and Susceptibility Testing to its MALDI Biotyper® Microbial Identification Platform

BREMEN, Germany, Sept. 26, 2017 /PRNewswire/ — Bruker today announced the closing of its acquisition of MERLIN Diagnostika GmbH, located near Bonn, Germany.  MERLIN has in-depth expertise in products, services and consulting in the fields of antibiotic resistance testing (ART) and antibiotic susceptibility testing (AST).  MERLIN’s technology and product portfolio for human and veterinary antibiotic resistance and specialty susceptibility testing further expands Bruker´s microbiology business, which is based on rapid, broad-based microbial identification using Bruker’s market-leading MALDI Biotyper(MBT) platform for proteomic fingerprinting.  Financial details were not disclosed. 

The principle of the MERLIN MICRONAUT™ system for specialty susceptibility testing is the phenotypic detection of microbial growth inhibition in the presence of antibiotics.  Its microdilution procedure is a standardized, globally accepted reference method for the determination of minimal inhibitory concentrations (MICs).  Standard and special AST plates are available for in-vitro diagnostic use according to the EU directive EC/98/79 for a wide spectrum of clinically important microorganisms.  MERLIN’s focus is on the detection of major resistance phenotypes, i.e. MRSA, VRE, MBL, ESBL, KPC, AMP-C, and OXA-48.  In addition, MERLIN has the ability to customize antibiograms for more than 200 antibiotics.  Due to this flexibility, the MICRONAUT system enables laboratories to adjust their testing profiles to the rapid spread of certain new resistances.  MICRONAUT software for identification and susceptibility testing includes an expert plausibility check, and has for several years already offered an interface to Bruker´s MALDI Biotyper.

MERLIN is a member of the German Diagnostic Industry Association (VDGH) and the Paul-Ehrlich-Society for Chemotherapy (, and MERLIN is involved in various studies related to antibiotic resistance, e.g. the monitoring of…
