At the 28th European Congress of Clinical Microbiology and Infectious Diseases (ECCMID 2018), Bruker introduces new diagnostic workflow solutions for rapid and cost-effective microbial identification and antibiotic resistance testing from positive blood cultures – called the integratedBologna Workflow. Bruker also launches additional molecular assays for comprehensive and fast invasive fungal disease (IFD) testing in blood, without the need for any culturing step.

Rapid and cost-effective positive blood culture (PBC) testing, including broad species identification (ID) and testing for the most important antibiotic resistance mechanisms, are urgent priorities in clinical microbiology, which require routine adoption for optimized patient benefits. The integratedBologna Workflowfor bloodstream infections has recently been introduced at the S. Orsola-Malpighi University Hospital in Bologna, Italy. The spread of resistance against third-generation Cephalosporins and Carbapenems among Gram-negative bacteria poses a high burden on the Italian healthcare system, and this problem is also rapidly increasing elsewhere in Europe. Starting from a PBC in hospital testing for bloodstream infections, Bruker's new, simplifiedFast Sepsitypersolution for theMALDI Biotyper(MBT)platform further reduces hands-on time and decreases time-to-result.

TheBologna Workflowcombines rapid ID with broad species coverage with theMBT STAR-Carbaassay for fast carbapenem-resistance testing, all within 60-90 minutes. An automated warning for carbapenem-resistantKlebsiella pneumoniae (KPC), associated with theblaKPCgene, is performed with an optional MBT subtyping module. For the S. Orsola-Malpighi University Hospital this makes up the majority ofKPCcases.KPC-subtyping occurs simultaneously with microbial ID, and a warning is displayed in the research-use-only version (RUO) of the MBT software, which has been validated by the hospital for internal use.

TheBologna Workflowis now further enhanced by the addition of the newMBT STAR-Cephakit (CE-IVD) for a MALDI-MS-based functional resistance test against third generation cephalosporins.

Due to the continuous expansion and refinements of theMALDI Biotyperreference library (CE-IVD), theBologna Workflowcan now also detect very rare species in a positive blood culture. Bruker is introducing a MBT reference library update at ECCMID, which adds another 239 species across 24 microbial genera. The library update also improves the coverage of biological diversity for many species. For example, it further improves the identification ofCandida auris,这是越来越causing fungal infections in critically ill hospital patients.Candida aurisis resistant against a number of antifungal agents and can cause blood stream infections, urinary tract infections and wound infections. Bruker is also introducing theMBT Filamentous Fungi Library 2.0as a RUO-version with 26 new species.

Miriam Cordovana, in the department of Bacteriology and Mycobacteriology of the S. Orsola-Malpighi University Hospital in Bologna, Italy, stated: "Using theMALDI BiotyperPositive Blood Culture (PBC) workflow, it is now possible to get fast and accurate microorganism identification and resistance detection within 60-90 minutes after a PBC alert, enabling a significantly shorter reporting time in comparison with current routine methods."

In addition, Bruker is launching the new RUOFungiplex普遍kit for broad-coverage, real-time PCR testing covering 23 filamentous fungi genera, which complements the existing more specific CE-IVDFungiplex Candidaspecies ID kit. As a complement to the existing CE-IVDFungiplex Aspergillusspecies ID kit, the newFungiplex Aspergillus Azole-R(CE-IVD) kit now also detects Azole-resistance. All Fungiplex assays are done directly on blood and without any need for cultures, which often grow very slowly, if at all.

This unique and powerful combination of fourFungiplexkits with fast time-to-result within 2-4 hours can now provide infectious disease doctors with a phased, comprehensive workflow for Invasive Fungal Disease (IFD) testing of critically ill patients in the hospital.

Wolfgang Pusch, Executive Vice President for Microbiology & Diagnostics at Bruker Daltonics, commented: "We now offer a very fast, compelling and cost-effective workflow for identification with extremely broad species coverage from positive blood cultures, integrated with rapid functional testing for resistance against carbapenems and cephalosporins, all on the established MALDI Biotyper platform. In contrast to competing syndromic panels for BSI, theBologna Workflowis cost-effective and suitable for broad clinical adoption. It covers identification of more than 2,700 microbial species, and two of the most important resistance mechanisms for Gram-negative bacteria, all in only 60-90 minutes after the blood culture has been flagged as positive. Optional RUOKPC-subtyping, simultaneous with ID and without additional cost, can provide resistance gene alerts that need to be validated by other methods."

About the BrukerMALDI Biotyper(MBT) Platform

TheMALDI Biotyperenables molecular identification of bacteria, yeasts and fungi. Classification and identification of microorganisms is achieved reliably and quickly using proteomic fingerprinting by high-throughput MALDI-TOF mass spectrometry. TheMALDI Biotyperuses a molecular approach based on specific proteomic fingerprints from bacterial strains. Many published studies have highlighted the greater accuracy and lower cost, as well as the typically much faster time-to-result (TTR).

Applications of variousMALDI Biotypersolutions include clinical routine microbial identification, environmental and pharmaceutical analysis, taxonomical research, food and consumer product safety and quality control, as well as marine microbiology. In many European and international laboratories theMALDI Biotyperhas replaced classical biochemical testing for bacterial identification in the past few years due to the accuracy, speed, extensive species coverage, ease of use and cost effectiveness of the system. Traditional biochemical techniques detect different metabolic properties of microorganisms, can take many hours or even days for completion, and they often lack specificity.

The robustMALDI Biotyperrequires minimal sample preparation and offers low consumables cost. The products of theMALDI Biotyperfamily are available in a research-use-only (RUO) version, as the U.S. FDA-clearedMALDI Biotyper CA System, or in an IVD-CE version according to EU directive EC/98/79. TheMALDI Biotyperalso has medical device registrations in numerous other countries.

RUO versions of theMALDI Biotypersoftware allow selected, high-value antimicrobial resistance tests. The CE-IVDMBTSTAR®-Cephakit now allows rapid, functional antibiotic resistance testing againstCephalosporins,and the CE-IVDMBT STAR-Carbakit is for fastCarbapenem为测试.
