Gene Expression and Cell Culture Assays Reveal Cheese Isolate Lactococcus Lactis MC5 May Influence the Virulence of Staphylococcus Aureus
Brazilian Journal of Microbiology(2023)
摘要
Staphylococcus aureus (SA) can thrive in a wide variety of hosts and environments, causing clinical infections and foodborne intoxications. In Brazil, SA is commonly isolated from traditional soft cheeses, especially those prepared from unpasteurized milk. In this research, the isolate S. aureus SABRC1 was evaluated for virulence traits under different conditions, including co-inoculation with Lactococcus lactis MC5 (isolated from “Fresh Minas Cheese”), which produces antibacterial peptides. Results from experiments with Caco-2 culture indicated S. aureus SABRC1 was able to adhere (42.83 ± 1.79
