Antibiotic resistances spread faster than so far thought

By studying fish raised in aquaculture, researchers from the Helmholtz Zentrum München, the University of Copenhagen and the University of Campinas in Brazil have shed new light on the mechanisms by which antibiotic resistance genes are transferred between bacteria. According to the study published in the journal 'Microbiome', those mechanisms are more varied than previously thought.  "In the past 70 years, the use of antibiotics in human and veterinary medicine has steadily increased, leading to a dramatic rise in resistant microorganisms," says Prof. Dr. Michael Schloter, head of the Research Unit for Comparative Microbiome Analyses (COMI) at Helmholtz Zentrum München. It is especially alarming that many microorganisms are resistant not just to one antibiotic, but to a whole range of different substances, states the corresponding author of the recent study. This poses particular problems in the treatment of infectious diseases. "We therefore set out to discover the mechanisms responsible for resistance development," he says.  Read more...
