Whole genome sequencing for surveillance of bacterial infectious illnesses

Abstract

This review summarises the current knowledge of whole genome sequencing (WGS) which has become the standard method for genetic characterisation of bacteria in surveillance and outbreak investigation. Although the method offers many advantages, its use in outbreak investigations is hampered by the relatively slow turn-around time. Using new approaches to perform WGS, typing and gene detection can now be completed within one day. This break-through allows clinical consequences to be taken almost immediately after detection of relevant bacteria and may have a huge impact on the future prevention of transmission of infectious diseases.
