[Infectious diseases in the genomic era].

Next generation sequencing (NGS) technologies have arrived, changing research and infectious disease research into a new era, the “genomic era”. Currently, the developed world is introducing NGS in a number of applications, including clinical diagnostics, epidemiology, and microbiology. In developing countries NGS is being progressively introduced. Technologies currently available allow to sequence the whole genome of bacterial and viral strains for an approximate cost of $100 USD, which is highly cost savings compared to old-technologies for genome sequencing. Here we review recent publication of whole genome sequencing used for, (i) tracking of foodborne outbreaks, with emphasis in Salmonella and Listeria monocytogenes, (ii) building genomic databases for Governments, (iii) investigating nosocomial infections, and (iv) clinical diagnosis. The genomic era is here to stay and researchers should use these “massive databases” generated by this technology to decrease infectious diseases and thus improve health of humans and animals.
