| Outline of Final Research Achievements |
We addressed the possible involvement of quorum sensing (QS) molecules, 3-oxo-C12-HSL and C4-HSL, from Pseudomonas aeruginosa to inhibition of methicillin-resistant Staphylococcus aureus (MRSA). We used Vancomycin (VCM) as a positive control. More than 10% Dimethyl sulfoxide (DMSO) had the effect of inhibition of MRSA, but on the other hand QS molecules had not that effect. In addition, the MRSA growth did not affect by the stimulation of 3-oxo-C12-HSL and
C4-HSL at the same time. Minimum inhibitory concentration of VCM showed 1 μg/ml. These results suggest that QS molecules, 3-oxo-C12-HSL and C4-HSL, have not effect to inhibition of MRSA.
