NGD Publications

Recent publications from our first deployments, where prospective WGS detected transmission and enabled outbreak to be prevented.

February 2023

Machine-Learning Model for Prediction of Cefepime Susceptibility in Escherichia coli from Whole-Genome Sequencing Data - Humphries et. al. February 2023, Journal of Clinical Microbiology

Blind validation of NGD's WGS-base machine learning model determining resistance to cefepime in E. coli.  At 97% accuracy, the model's results were found to be more accurate than that of the standard of care.  The paper reports among the most accurate WGS-based models for the determination of resistance in Gram negative bacteria.

February 2020

Evaluation of a fully automated bioinformatics tool to predict antibiotic resistance from MRSA genomes — Kumar et. al. February 2020, Journal of Antimicrobial Chemotherapy

A validation of the NGD susceptibility prediction system, against 798 distinct strains, versus VITEK2.  All discords, initially approximately 3.5%, were retested, with most reversing to accord with the sequence-based prediction.  Finds validated accuracy of 99.7% for the NGD susceptibility diagnostic, establishing that sequence is the new standard for the determination of S. aureus susceptibility.

November 2019

Pilot Evaluation of a Fully Automated Bioinformatics System for Analysis of Methicillin-Resistant Staphylococcus aureus Genomes and Detection of Outbreaks — Brown et. al. November 2019, Journal of Clinical Microbiology

The first use of prospective, consecutive WGS to catch transmission and prevent outbreak.  Documents the first case where transmission in a diabetic foot clinic, mediated by a caregiver, was discovered by prospective WGS, enabling prompt and effective intervention.
