Impact of whole genome sequencing in Public Health reference laboratories

Abstract

Public Health Microbiology reference laboratories fulfil a critical role in providing overarching testing and surveillance for notifiable, emerging and important pathogens. These duties require the laboratory to possess an extensive repertoire of validated assays and the ability to rapidly respond to novel threats and outbreaks. For these, among other reasons, the ‘one stop shop' approach of whole genome sequencing (WGS) has been embraced by microbiology reference laboratories. The ability to replace multiple labour-intensive assays with a single technique of superior typeability and discrimination at an often competitive price, although not without its challenges, has already begun to change the workflow of Public Health reference laboratories.
