| Study Title | The growth and virulence of S. aureus is inhibited by C. striatum by inhibiting its arginine biosynthesis pathway |
| Study Summary | Background: Patients with chronic rhinosinusitis (CRS) exhibit signs of nasal microbiota dysbiosis, specifically manifested by an increase in the relative abundance of Staphylococcus species and a decrease in the relative abundance of Corynebacterium species. This alteration may be closely associated with the pathogenesis of CRS. Understanding how commensal bacteria interact with pathogenic bacteria can help us reconstruct the homeostasis of nasal microbiota and promote nasal health. Method and Results: We conducted an in vitro co-culture model of Staphylococcus aureus and Corynebacterium striatum. Through metabolomic analysis, we discovered that the metabolic pathways of S. aureus were downregulated considerably during co-culture, especially for the arginine biosynthesis pathway. We later conducted validation experiments involving arginine supplementation and air-liquid interface culture of human nasal epithelial cells. Conclusion: The growth and virulence of S. aureus is inhibited by C. striatum by inhibiting its arginine biosynthesis pathway. |
