Súhrn: Staphylococcus aureus is the most common food pathogen associated with biofilm formation. Matrix adhesion genes related to the biofilm formation isdB and sdrE was detected in two strains or in three strains. Genes hla and isdA were occurred in all staphylococcal strains. The objective of this study is to compare the stainless steel and microtiter plate surfaces for testing the antibiofilm activity of cell-free supernatant from lactobacilli and plant extracts in four milk Staphylococcus aureus. The results showed high biofilm formation of Staphylococcus aureus on stainless steel surfaces and anti-biofilm effect of Lactobacillus supernatant and plant extracts.
