Summary
A team of scientists at the Cambridge University Hospitals NHS Foundation Trust, University of Cambridge, Wellcome Sanger Institute and the London School of Hygiene and Tropical Medicine have gone a step forward by establishing the agreement between culture-based laboratory methods and genome sequencing for antibiotic resistance determination in Enterococcus faecium, one of the top 10 bacterial pathogens with the highest mortality burden globally. The team curated a set of over 200 genetic markers that most accurately predict resistance to 12 different, clinically relevant antibiotics in a collection of over 4,000 E. faecium strains. For key antibiotics such as ampicillin, ciprofloxacin, vancomycin and linezolid, the team reported very high diagnostic accuracy, and improved accuracy for the detection of resistance to other antibiotics compared to previous state-of-the-art predictive methods. In addition, the authors implemented the antibiotic resistance predictions on Pathogenwatch
