OpGen Data Predicting Phenotypic Antimicrobial Susceptibility Published in Diagnostic Microbiology & Infectious Disease Journal

In an analysis of K. pneumoniae bacterial isolates, an overall agreement of 95.6% was observed between phenotypic antimicrobial susceptibility and genotypic prediction by OpGen’s Acuitas Lighthouse® platform using whole genome sequencing data

GAITHERSBURG, Md., March 23, 2020 (GLOBE NEWSWIRE) -- OpGen, Inc. (Nasdaq: OPGN) announced today that its Acuitas Lighthouse® was used in a study conducted by the Mayo Clinic to predict phenotypic resistance and antimicrobial susceptibility among clinical isolates from the Antimicrobial Resistance Leadership Group (ARLG). The findings were published in Diagnostic Microbiology & Infectious Disease, a peer-reviewed scientific journal providing the latest developments in clinical microbiology and the diagnosis and treatment of infectious diseases.

The manuscript titled ‘Core genome MLST and resistome analysis of Klebsiella pneumoniae using a clinically-amenable workflow,’ was authored by a team of researchers at Mayo Clinic and others in the ARLG.

The manuscript showcases the use of core genome multi locus sequence typing (cgMLST) and whole genome sequencing (WGS) data, analyzed by OpGen’s Acuitas Lighthouse Software to predict phenotypic antimicrobial susceptibility (AST). The analysis was performed on forty (40), K. pneumoniae bacterial isolates from the ARLG isolate collection. The overall agreement between phenotypic AST and genotypic prediction was 95.6%.

“This research study is another important milestone for OpGen, demonstrating the capabilities of Acuitas Lighthouse using Mayo Clinic’s WGS data to predict phenotypic AST,” said Evan Jones, CEO of OpGen. “Our Acuitas Lighthouse is versatile and has now been shown to have utility with WGS data in addition to PCR test results.”
