Scientists from Greifswald Throw Light on Outbreak of Multidrug Resistant Bacteria in Vorpommern

    Scientists from the University of Greifswald and University Medicine Greifswald have collaborated with the Robert Koch Institute (RKI) and various institutions from across Germany to analyse an outbreak of particularly multidrug resistant bacteria belonging to the species Klebsiella pneumoniae. The results have been published in the journal Genome Medicine (DOI: 10.1186/s13073-020-00814-6). The team, which was led by Dr. Katharina Schaufler, was able to prove that the bacteria clone was a dangerous subtype, which was resistant against various kinds of medication, including two important drugs of last resort.

    Multidrug resistant Klebsiella pneumoniae are a major cause of infections caught at and outside of hospitals that include sepsis (so-called ‘blood poisoning’), liver abscesses, urinary tract infections and pneumonia. Infections with these multidrug resistant bacteria often lead to severe or even fatal courses of illness. An outbreak of this kind of bacteria was registered in medical facilities in Vorpommern from June to October 2019.

    Scientists from Greifswald have been able to determine and analyse the full genotype of these bacteria and functional experiments were also performed in a laboratory. They observed that the bacteria showed extensive resistance and even remained stable against two so-called drugs of last resort, Colistin and Meropenem. These antibiotics are only used very sparingly, for example for treating severe courses of illness. In addition to their distinct multidrug resistance, these bacteria have characteristics that make them even more resilient and dangerous than other members of the same species of bacteria. This is one of the possible reasons why they were able to spread among various patients in the district of Vorpommern-Greifswald in summer 2019.

    Thanks to the immediate intervention of Vorpommern’s medical facilities and the public health system, their close collaboration in the regional network for combatting multidrug resistant pathogens KOMPASS e. V., as well as the interdisciplinary collaboration between scientists at University Medicine, the University of Greifswald, and the RKI, it was possible to successfully contain the outbreak within a short amount of time. The study helped improve the microbiological and epidemiological understanding of the bacteria clone and can help to make sure that more consideration is given to the occurrence of dangerous bacterial subtypes and that these are identified faster when implementing control measures and monitoring strategies in the future.
