Dialogue between Staphylococcus aureus SA15 and Lactococcus garvieae strains experiencing oxidative stress.

ABSTRACT:

Background

Staphylococcus aureus is an important foodborne pathogen. Lactococcus garvieae is a lactic acid bacterium found in dairy products; some of its strains are able to inhibit S. aureus growth by producing H₂O₂. Three strains of L. garvieae from different origins were tested for their ability to inhibit S. aureus SA15 growth. Two conditions were tested, one in which H₂O₂ was produced (high aeration) and another one in which it was not detected (low aeration). Several S. aureus genes related to stress, H₂O₂-response and virulence were examined in order to compare their level of expression depending on the inoculated L. garvieae strain.
