The carrier strain of S. aureus displays greater attachment to NEC than the non-carrier strain. Nasal epithelial cell layers, which had been cultured at the air–liquid interphase in antibiotic-free medium, were inoculated with 38 ± 4 (mean ± SEM) bacteria/well to assess bacterial growth dynamics. The organisms used were S. aureus D30 (SA D30), S. aureus 930918 (SA 930918), and S. epidermidis (SE). The apical surface of the NEC layers was washed after 4 hr and then sonicated to detach bacteria, which were subsequently enumerated on TSA. The results are expressed as CFU and represent the mean ± SEM of quadruplicate experiments.
