Superbug Genome Sequenced - Drug Discovery and Development

The genome of a newly-emerging superbug, commonly known as Steno, has just been sequenced. The results reveal an organism with a remarkable capacity for drug resistance. The research was carried out by scientists at the Wellcome Trust Sanger Institute near Cambridge and the University of Bristol. Understanding the genome of this bacterium will help researchers discover how to deal with this particularly resistant organism. The paper will be published in Genome Biology.

Dr Matthew Avison from the University of Bristol, and senior author on the paper said: “This is the latest in an ever-increasing list of antibiotic-resistant hospital superbugs. The degree of resistance it shows is very worrying. Strains are now emerging that are resistant to all available antibiotics, and no new drugs capable of combating these ‘pan-resistant’ strains are currently in development.”

Pan-resistant Steno infections are at least as hard to treat as MRSA and C.diff infections. But although it is common in the environment, Steno infections are rarer than MRSA and C.diff infections and are exclusively hospital-acquired.
