Isolates were identified using matrix\u2010assisted laser desorption\/ionisation time\u2010of\u2010flight mass spectrometry, and antimicrobial susceptibility testing was performed by gradient diffusion. Whole\u2010genome sequencing with multilocus sequence typing (MLST) characterised\n \n Staphylococcus aureus<\/jats:italic>\n <\/jats:styled-content>\n lineages.\n In silico<\/jats:italic>\n PCR differentiated Group A and Group B\n \n Staphylococcus delphini<\/jats:italic>\n <\/jats:styled-content>\n . Sampling site sensitivity was calculated using a multisite composite reference. Mixed\u2010effects logistic regression evaluated associations between demographic factors and carriage.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Carriage of any staphylococcal species occurred in 111 of 150 (74%) horses:\n \n S. aureus<\/jats:italic>\n <\/jats:styled-content>\n 28 of 150 horses (18.7%) and\n \n S.\u00a0delphini<\/jats:italic>\n <\/jats:styled-content>\n 23 of 150 horses (15.3%). Increasing age was associated with decreased odds of CoPS isolation (odds ratio 0.92\/year; 95% confidence interval 0.86\u20130.98). The nares were the most sensitive single sampling site, whereas multisite sampling improved detection. Meticillin\u2013resistance was absent in all CoPS isolates, and\n \n S. delphini<\/jats:italic>\n <\/jats:styled-content>\n isolates were fully susceptible to all antimicrobials tested. MLST revealed multiple\n \n S. aureus<\/jats:italic>\n <\/jats:styled-content>\n sequence types, some of which were shared across multiple horses at some boarding facilities. Both groups of\n \n S. delphini<\/jats:italic>\n <\/jats:styled-content>\n lineage were identified, although many isolates were nontypable.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions and Clinical Relevance<\/jats:title>\n \n Healthy horses harbour\n \n S. aureus<\/jats:italic>\n <\/jats:styled-content>\n and\n \n S. delphini<\/jats:italic>\n <\/jats:styled-content>\n , with minimal antimicrobial resistance.
