Abstract
Staphylococcus aureus showed a significant increase in relative abundance in CRSwNP patients following endoscopic sinus surgery compared to pre-surgery samples. Other Staphylococcus species were found to correlate positively with S. aureus in patients with nasal polyps; among those, S. caprae correlated strongly while being the most represented in samples. Patients with recurrent nasal polyp growth exhibited a substantially greater postoperative increase in the relative abundance of S. aureus.
