At the 112th General Meeting of the American Society of Microbiology (ASM) in San Francisco, Bruker announces a new collaboration with JMI Laboratories in the field of fungal identification by proteomics fingerprinting. JMI Laboratories is applying the Bruker MALDI Biotyper™ to a wide variety of international antimicrobial resistance surveillance studies utilizing the SENTRY Program platform (>300 sites in more than 40 countries and six continents). Among these programs, comprehensive sampling of invasive fungal infections involves nearly 2,000 samples of yeast and moulds, each requiring the highest quality of identifications, and currently requiring gene amplification and sequencing. The Bruker MALDI Biotyper will streamline reference-quality identifications via its rapidly evolving library of clinically important fungi.
“Contemporary understanding of emerging resistances among antifungal agents requires companion use of reference susceptibility test methods such as CLSI and EUCAST and molecular-level reference-quality organism identifications. The Bruker MALDI Biotyper provides us with an evolving degree of species identification certainty and processing value.”
Invasive fungal infections are associated with high morbidity and mortality while prompt diagnosis can result in more optimized therapy reducing both mortality and costs of treatment. Current methods for identification of fungi include biochemical, phenotypic, microscopic and molecular methods. Numerous peer-reviewed studies have examined the capabilities of the MALDI Biotyper for fungal identification and Bruker recently launched a separate RUO library of filamentous fungi at ECCMID 2012. MALDI Biotyper testing can be completed in hours and therefore has the potential to produce more rapid results than traditional microbiological testing methods.
The goals of this collaboration include the validation and expansion of the MALDI Biotyper database of protein fingerprint profiles for identification of unusual filamentous fungi, and the expansion of protein fingerprint profiles for identification of unusual yeast species. It therefore will enhance the MALDI Biotyper database as well as determine if the Bruker MALDI Biotyper platform can partially or fully replace the laborious traditional biochemical testing currently used by JMI Laboratories.
