Large-scale characterisation of the nasal microbiome redefines Staphylococcus aureus colonisation status.

ABSTRACT: Staphylococcus aureus colonises the nose in humans, with individuals defined as persistent, intermittent or non-carriers. Unlike the gut microbiome, the nasal microbiome has not been studied in large numbers of people. Here, we define the nasal microbiome in ~1100 individuals from the CARRIAGE study (ISRCTN: ISRCTN10474633) and combine with S. aureus culture data. We identify seven community state types (CST), including two CSTs more common in females. Approximately 70% of those who are persistently colonised with S. aureus have a CST dominated by S. aureus, while non-carriers are distributed across the other six CSTs. Intermittent carriers are not a unique state but have microbiomes that resemble non- or persistent carriers. Persistent carriage is positively associated with S. aureus abun
