Summary, in English

A variety of pathogenic bacteria can infect humans and the increase in bacteria resistant to common antibiotics is a large threat to human health worldwide. This work presents a method, based on optical DNA mapping (ODM) in nanofluidic channels, that can detect the type of bacterial present in a sample by matching the obtained maps of large DNA molecules to a database of fully assembled bacterial genomes. The extraction and labelling protocol has been designed to work for both Gram-positive and Gram-negative bacteria, not requiring any prior knowledge about the sample content.
