Effect of the 59 non-aureus Staphylococcus (NAS) isolates on S. aureus (S. a.) biofilm formation (CFU/mL of the biofilm fraction). For dual-species biofilms, S. aureus 8325-4 (agr +) was co-cultured 24 h together with A S. chromogenes (S. c.), S. epidermidis (S. e.) and S. simulans (S. s.); B originating from milk or teat apices (TA); C harboring biofilm-related genes (BG) or not (NBG); D with the capacity to produce biofilm themselves (BP) or not (NBP); E with the capacity to inhibit the growth of S. aureus (GI) or not (NGI) and compared to biofilm formed by S. aureus alone (black bars).
