Biofilm formation by Salmonella Typhimurium and Staphylococcus aureus on stainless steel under either mono- or dual-species multi-strain conditions and resistance of sessile communities to sub-lethal chemical disinfection
S. enterica and S. aureus formed mono- and dual-species biofilms on stainless steel. Both bacterial species formed less biofilm (ca. 10-fold) under co-culture. Resistance of each species was not influenced by interspecies interactions. Bacterial interactions influenced both dominance and resistance of each strain. Inter-and intra-species interactions must be considered in the study of biofilms.
